Abstract
The invention comprises a solution of acetylene in a N-alkyl-1-pyrrolidone, the alkyl radical of which is a saturated hydrocarbon radical not containing more than 3 carbon atoms, and a process for the removal of acetylene from a gaseous mixture containing the same which consists in treating with a N-alkyl-1-pyrrolidone, the alkyl radical of which has the significance indicated above, to absorb the acetylene. The gaseous mixture may be treated under pressure, and the acetylene may be recovered from the solution by releasing the pressure or raising the temperature. N-methyl-1-pyrrolidone is particularly referred to.
