Abstract
Способ выделения перхлорвиниловой смолы из раствора в хлорорганическом растворителе, включающий распыление раствора в циркулирующую в высадительной колонне воду и обработку водяным паром, отличающийся тем, что, с целью повышения производительности способа и снижения содержания растворителя в получаемой крошке смолы, раствор смолы приводят в контакт на 0,02 - 0,8 с с водяным паром с температурой 120 - 330C на стадии распыления раствора перед подачей его в воду, причем отношение количества пара к раствору смолы составляет от 1,2 до 3,5.A method for separating perchlorovinyl resin from a solution in an organochlorine solvent, including spraying the solution into water circulating in the drop tower and steam treatment, characterized in that, in order to increase the productivity of the method and reduce the solvent content in the resulting crumb of the resin, the resin solution is brought into contact with , 02 - 0.8 with steam with a temperature of 120 - 330C at the stage of spraying the solution before feeding it into the water, and the ratio of the amount of steam to the resin solution is from 1.2 to 3.5.
