Abstract
Procedimiento par ala fabricación de clorhidrinas olefínicas, partiendo de gas con bajo contenido de olefinas, caracterizado por el hecho de que la reacción en fase acuosa entre el cloro y una mezcla conteniendo olefinas, se efectua en presencia de un exceso de cloro sobre la cantidad necesaria par ala reacción y en que, el exceso de cloro es absorvido por medio de bases alcalinas para obtener soluciones de hipocloritos alcalinos, que son retornadas al ciclo donde producen ácido hipocloroso propio para reaccionar todavía con la olefina.Process for the manufacture of olefinic chlorohydrins, starting from gas with a low olefin content, characterized by the fact that the reaction in aqueous phase between chlorine and a mixture containing olefins is carried out in the presence of an excess of chlorine over the necessary quantity For the reaction and in that, the excess of chlorine is absorbed by means of alkaline bases to obtain solutions of alkaline hypochlorites, which are returned to the cycle where they produce their own hypochlorous acid to still react with the olefin.
