Abstract

Acetylene obtained from hydrocarbons, e.g. by partial combustion or electric arc cracking is purified by contact with 85-90% sulphuric acid at 30-40 DEG C. to remove other unsaturated and organic or inorganic sulphur compounds. The purification is preferably effected by countercurrent contact, e.g. in a tower packed with Raschig rings.
