Abstract
Process for the purification of concentrated acetylene obtained by thermal decomposition of hydrocarbons to remove them from small quantities of unsaturated hydrocarbons with more than 2 carbon atoms removed in the previous treatment of this acetylene depuration, because this acetylene concentrate is washed by means of a mixture constituted by sulfuric acid and p-toluenesulfonic acid in the latter in an amount not exceeding 5% of the volume of sulfuric acid.
