It was also used to replace gunpowder as a low-order explosive in mining and other applications. The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose.
The quality of the cellulose is important. Hemicellulose, lignin, pentosans, and mineral salts give inferior nitrocelluloses.
In precise chemical terms, nitrocellulose is not a nitro compound , but a nitrate ester. The glucose repeat unit anhydroglucose within the cellulose chain has three OH groups, each of which can form a nitrate ester.
Thus, nitrocellulose can denote mononitrocellulose , dinitrocellulose , and trinitrocellulose , or a mixture thereof. With fewer OH groups than the parent cellulose, nitrocelluloses do not aggregate by hydrogen bonding.
The overarching consequence is the nitrocellulose is soluble in organic solvents. Most lacquers are prepared from the dinitrate whereas explosives are mainly the trinitrate.
The principal use of cellulose nitrate is for the production of explosives, lacquers , and celluloid. The explosive applications are discussed below.
In terms of lacquers, nitrocellulose dissolves readily in organic solvents, which upon evaporation leaves a colorless, transparent, flexible films.
Around Christian Friedrich Schönbein , a German-Swiss chemist, discovered a more practical formulation. He reached for the nearest cloth, a cotton apron, and wiped it up.
He hung the apron on the stove door to dry, and as soon as it was dry, a flash occurred as the apron ignited.
His preparation method was the first to be widely used. The method was to immerse one part of fine cotton in 15 parts of an equal blend of sulfuric acid and nitric acid.
After two minutes, the cotton was removed and washed in cold water to set the esterification level and to remove all acid residue.
Schönbein collaborated with the Frankfurt professor Rudolf Christian Böttger , who had discovered the process independently in the same year.
By coincidence, a third chemist, the Brunswick professor F. Otto had also produced guncotton in and was the first to publish the process, much to the disappointment of Schönbein and Böttger.
The manufacturing process was not properly understood and few safety measures were put in place. A serious explosion that July killed almost two dozen workers, resulting in the immediate closure of the plant.
Guncotton manufacture ceased for over 15 years until a safer procedure could be developed. The British chemist Frederick Augustus Abel developed the first safe process for guncotton manufacture, which he patented in The washing and drying times of the nitrocellulose were both extended to 48 hours and repeated eight times over.
The acid mixture was changed to two parts sulfuric acid to one part nitric. Nitration can be controlled by adjusting acid concentrations and reaction temperature.
Soluble nitrocellulose, or a solution thereof, is sometimes called collodion. More-stable and slower-burning collodion mixtures were eventually prepared using less-concentrated acids at lower temperatures for smokeless powder in firearms.
The first practical smokeless powder made from nitrocellulose, for firearms and artillery ammunition, was invented by French chemist Paul Vieille in Jules Verne viewed the development of guncotton with optimism.
He referred to the substance several times in his novels. His adventurers carried firearms employing this substance. In his From the Earth to the Moon , guncotton was used to launch a projectile into space.
Because of their fluffy and nearly white appearance, nitrocellulose products are often referred to as cottons, e. Guncotton was originally made from cotton as the source of cellulose but contemporary methods use highly processed cellulose from wood pulp.
While guncotton is dangerous to store, the hazards it presents can be reduced by storing it dampened with various liquids, such as alcohol. For this reason, accounts of guncotton usage dating from the early 20th century refer to "wet guncotton.
The power of guncotton made it suitable for blasting. As a projectile driver, it had around six times the gas generation of an equal volume of black powder and produced less smoke and less heating.
Further research indicated the importance of washing the acidified cotton. Unwashed nitrocellulose sometimes called pyrocellulose may spontaneously ignite and explode at room temperature , as the evaporation of water results in the concentration of unreacted acid.
Cellulose is treated with sulfuric acid and potassium nitrate to give cellulose mononitrate. This was used commercially as 'celluloid', a highly flammable plastic used until the midth century for lacquers and photographic film.
On May 2, , Hannibal Goodwin filed a patent for "a photographic pellicle and process of producing same Nitrocellulose was used as the first flexible film base , beginning with Eastman Kodak products in August, Camphor is used as a plasticizer for nitrocellulose film, often called nitrate film.
Nitrate film was used for X-ray photography for some time, where its hazardous nature was most acute, thus in , became disused for such purposes, along with its uses for motion-picture films in , when it was replaced by cellulose acetate film commonly known as safety film.
Nitrocellulose X-ray film ignition was the cause of the Cleveland Clinic fire of in Cleveland, Ohio , which claimed the lives of people during the fire and of a number who were rescued but died several days later due to inhalation of toxic smoke.
The use of nitrocellulose film for motion pictures led to the requirement for fireproof projection rooms with wall coverings made of asbestos.
A training film for projectionists included footage of a controlled ignition of a reel of nitrate film, which continued to burn when fully submerged in water.
Unlike many other flammable materials, nitrocellulose does not need air to continue burning, as the material contains sufficient oxygen within its molecular structure.
For this reason, immersing burning film in water may not extinguish it, and could actually increase the amount of smoke produced.
Cinema fires caused by ignition of nitrocellulose film stock were the cause of the Dromcolliher cinema tragedy in County Limerick in which 48 people died and the Glen Cinema disaster in Paisley, Scotland , which killed 69 children.
Today, nitrate film projection is rare and normally highly regulated and requires extensive precautionary measures including extra projectionist health and safety training.
Projectors certified to run nitrate films have many precautions, among them the chambering of the feed and takeup reels in thick metal covers with small slits to allow the film to run through.
The projector is modified to accommodate several fire extinguishers with nozzles aimed at the film gate. The extinguishers automatically trigger if a piece of flammable fabric placed near the gate starts to burn.
While this triggering would likely damage or destroy a significant portion of the projection components, it would prevent a fire which could cause far greater damage.
Projection rooms may be required to have automatic metal covers for the projection windows, preventing the spread of fire to the auditorium.
The Dryden Theatre at the George Eastman Museum is one of a few theaters in the world that is capable of safely projecting nitrate films,  and regularly screens films to the public.
Nitrocellulose was found to gradually decompose, releasing nitric acid and further catalyzing the decomposition eventually into a flammable powder.
Decades later, storage at low temperatures was discovered as a means of delaying these reactions indefinitely.
The great majority of films produced during the early 20th century are thought to have been lost either through this accelerating, self-catalyzed disintegration or through studio warehouse fires.
Salvaging old films is a major problem for film archivists see film preservation. Nitrocellulose film base manufactured by Kodak can be identified by the presence of the word 'nitrate' in dark letters along one edge; the word only in clear letters on a dark background indicates derivation from a nitrate base original negative or projection print, but the film in hand itself may be a later print or copy negative, made on safety film.
Acetate film manufactured during the era when nitrate films were still in use was marked 'Safety' or 'Safety Film' along one edge in dark letters.
While cellulose acetate-based so-called "safety film", notably cellulose diacetate and cellulose acetate propionate, was produced in the gauge for small-scale use in niche applications such as printing advertisements and other short films to enable them to be sent through the mails without the need for fire safety precautions , the early generations of safety film base had two major disadvantages relative to nitrate: it was much more expensive to manufacture, and considerably less durable in repeated projection.
The cost of the safety precautions associated with the use of nitrate was significantly lower than the cost of using any of the safety bases available before These drawbacks were eventually overcome with the launch of cellulose triacetate base film by Eastman Kodak in The crucial advantage cellulose triacetate had over nitrate was that it was no more of a fire risk than paper the stock is often referred to as "non-flam": this is true—but it is combustible, just not in as volatile or as dangerous a way as nitrate , while it almost matched the cost and durability of nitrate.
Polyester is much more resistant to polymer degradation than either nitrate or triacetate. Although triacetate does not decompose in as dangerous a way as nitrate does, it is still subject to a process known as deacetylation, often nicknamed "vinegar syndrome" due to the acetic acid smell of decomposing film by archivists, which causes the film to shrink, deform, become brittle and eventually unusable.
Triacetate remains in use for most camera negative stocks because it can be "invisibly" spliced using solvents during negative assembly, while polyester film can only be spliced using adhesive tape patches or ultrasonically, both of which leave visible marks in the frame area.
Also, polyester film is so strong, it will not break under tension and may cause serious damage to expensive camera or projector mechanisms in the event of a film jam, whereas triacetate film breaks easily, reducing the risk of damage.
Many were opposed to the use of polyester for release prints for precisely this reason, and because ultrasonic splicers are very expensive items, beyond the budgets of many smaller theaters.
In practice, though, this has not proved to be as much of a problem as was feared. Rather, with the increased use of automated long-play systems in cinemas, the greater strength of polyester has been a significant advantage in lessening the risk of a film performance being interrupted by a film break.
Despite its self-oxidizing hazards, nitrate is still regarded highly as the stock is more transparent than replacement stocks, and older films used denser silver in the emulsion.
The combination results in a notably more luminous image with a high contrast ratio. Because of its explosive nature, not all applications of nitrocellulose were successful.
John Wesley Hyatt created the winning replacement, which he created with a new material he invented called camphored nitrocellulose—the first thermoplastic , better known as celluloid.
The invention enjoyed a brief popularity, but the Hyatt balls were extremely flammable, and sometimes portions of the outer shell would explode upon impact.
An owner of a billiard saloon in Colorado wrote to Hyatt about the explosive tendencies, saying that he did not mind very much personally but for the fact that every man in his saloon immediately pulled a gun at the sound.
Pressure was applied to the liquid in the cylinder, which resulted in a uniform compression on the nitrocellulose mass, compressing it into a uniform sphere as the heat vaporized the solvents.
