why is acetylene gas dissolved in liquid acetone and shipped in cylinders filled with a porous filler
it keeps acetylene from reaching its critical point
Acetylene gas is highly unstable and can decompose explosively if it is subjected to shock, friction, or high temperatures. Therefore, it is dissolved in liquid acetone (C3H6O) to stabilize it and make it easier to transport and handle. When acetylene molecules are dissolved in acetone, the acetone molecules surround and stabilize them, ensuring that they do not come into contact with air or any other oxidizing substances.
The acetylene gas is shipped in cylinders filled with a porous filler such as diatomaceous earth or activated charcoal. The porous filler helps to increase the surface area of the acetone, thereby enhancing the amount of acetylene that can be dissolved. The filler also helps to prevent the acetone from sloshing around in the cylinder during transport, which could cause the cylinder to rupture.
The porous filler also acts as a safety device in case of a cylinder leak. If a cylinder develops a leak, the acetylene gas will be released slowly and mix with the surrounding air. This could create an explosive mixture if the concentration of acetylene in the air reaches a certain level. However, the porous filler will act as a flame arrestor, preventing any sparks or flames from igniting the acetylene gas. This makes the transport and handling of acetylene gas much safer.
