Abstract
An oxidative aqueous solution for the purification of carbide acetylene that is acetylene, containing hydrogen phosphide and hydrogen sulphide admixtures, comprising cupric chloride, mercuric chloride and hydrochloric acid. The proposed solution has a high activity and the ability of purifying a great amount of acetylene in one purification cycle before regeneration. One liter of the solution before regeneration purifies 300 - 6000 liters of carbide acetylene, that is, acetylene at a space velocity of 30 to 80 min.sup..sup.-1. The solution is noted for its stability. In case of alternating the cycles of acetylene purification and solution regeneration 1 liter of this solution purifies 10000 to 30000 liters of acetylene without the additional introduction of the initial components into the solution.
