Claims (4)

1. Способ гидролиза карбида кальция, заключающийся в разложении карбида кальция водой, отличающийся тем, что для гидролиза готовят гидролизный раствор из смеси воды и инертного растворителя, а после гидролиза пары инертного растворителя конденсируют, получая товарные продукты ацетилен, безводный инертный растворитель и известь.1. The method of hydrolysis of calcium carbide, which consists in the decomposition of calcium carbide with water, characterized in that a hydrolysis solution is prepared from a mixture of water and an inert solvent for hydrolysis, and after hydrolysis, the inert solvent vapor is condensed to produce acetylene, anhydrous inert solvent and lime. 2. Способ по п.1, отличающийся тем, что инертный растворитель отделяют от получаемой извести отстаиванием, центрифугированием и др.2. The method according to claim 1, characterized in that the inert solvent is separated from the lime obtained by sedimentation, centrifugation, etc. 3. Способ по п.1, отличающийся тем, что для гидролизного раствора в качестве инертного растворителя используют этиловый спирт в количестве 68%≤(Сспирт)<100%, остальное вода, где (Cспирт) - концентрация спирта, мас.%.3. The method according to claim 1, characterized in that for the hydrolysis solution, ethyl alcohol in the amount of 68% ≤ (C alcohol ) <100%, the rest is water, where (C alcohol ) is the alcohol concentration, wt.% . 4.
