Pyrolized dissolved technical acetylene
The formula - C2H2
Relative molecular weight (on the international nuclear weights of 1987) - 26,04
Acetylene density at 0°C and 0,1 МPa - 1,173 kg/m3
Acetylene dissolved technical, received by pyrolysis of hydrocarbons, represents being under pressure in a cylinder an acetylene solution in the acetone, equally spaced in porous bulk. The dissolved acetylene is intended for gas-flame processing of metals, supply of lighting equipment, laboratory work and other purposes.
