What is guncotton used for?

Guncotton, or nitrocellulose (also known as trinitrocellulose and cellulose nitrate) is a mild explosive, used in rockets, propellants, printing ink bases, leather finishing, and celluloid (a mixture of nitrocellulose and camphor; first used to manufacture billiard balls).

What is nitrocellulose made of?

Nitrocellulose is made by treating cellulose with a mixture of sulfuric and nitric acids. This changes the hydroxyl groups (–OH) in the cellulose to nitro groups (–NO3) as shown in Fig. 13.4. Nitrocellulose, also know as gun cotton and the main ingredient of smokeless gunpowder, decomposes explosively.

Is nitrocellulose a plastic?

Nitrocellulose plastics are quite resistant to common acid and alkali attack at ambient temperatures, are noncompressible, transparent in thin laminae, dif- ficult to twist, and extremely resistant to tearing.

How can I make nitric acid at home?

Dissolve 80 grams (2.8 oz) of nitrate salt in 50 millilitres (1.7 fl oz) of water. Start by portioning out your nitrate salt into a small glass mixing container. Then, pour in all of the water at once. Swirl the mixture around inside the container to help it dissolve faster.

How is guncotton made?

Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid.

Is Guncotton still used?

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 1865.

What is nitrocellulose plastic?

Nitrocellulose (NC), also called cellulose nitrate, is the oldest thermoplastic. NC’s with about 2 nitrate groups per glucose repeat unit are often chosen in plastics and laquers. A higher nitrate content is used in explosives.

What is the use of guncotton?

Guncotton is employed in gunpowders, solid rocket propellants, and explosives. In explosive: Nitrocellulosic explosives (guncotton) in 1845 by dipping cotton in a mixture of nitric and sulfuric acids and then removing the acids by washing with water, he hoped to obtain a propellant for military weapons.

When was guncotton first used as an explosive?

Safe and sustained production of guncotton began at the Waltham Abbey Royal Gunpowder Mills in the 1860s, and the material rapidly became the dominant explosive, becoming the standard for military warheads, although it remained too potent to be used as a propellant.

What happens when you heat guncotton?

Guncotton is unstable to heat, and even carefully prepared samples will ignite on a brief heating to temperatures in excess of 150 °C (300 °F). Guncotton is employed in gunpowders, solid rocket propellants, and explosives. Moderately nitrated cellulose (containing approximately 10.5 to 12.5 percent… It proved, however, to be too fast and violent.
