Description
Ы-0/сс«-диэтилен-2-бензтиазолсульфенамид вл етс ускорителем вулканизации каучука.B-0 / cc ' -dietylene-2-benzthiazole sulfenamide is a rubber vulcanization accelerator.
Известен способ получени М-ол:си-диэтилен-2-бензтиазолсульфенамида путем взаимодействи меркаптобензтиазола с морфолнном в органическом растворителе.A known method for the preparation of M-ol: C-diethylene-2-benzthiazole sulfenamide is obtained by reacting mercaptobenzthiazole with morphite in an organic solvent.
Способ сложен в технологическом оформлении, так как св зан с регенерацией растворител .The process is difficult to process, since it is associated with the regeneration of the solvent.
Предложен способ получени целевого продукта путем взаимодействи морфолина, меркаптобензотиазола и газообразного хлора в присутствии воды и щелочи.A method for the production of the desired product by reacting morpholine, mercaptobenzothiazole and chlorine gas in the presence of water and alkali is proposed.
Способ состоит в том, что процесс провод т в одну стадию, действием на раствор газообразного меркаптобензотиазола в морфолине в присутствии небольшого количества воды и щелочи.The method consists in the fact that the process is carried out in one stage by the action of a solution of gaseous mercaptobenzothiazole in morpholine in the presence of a small amount of water and alkali.
Пример. Приготовл ют раствор из 48 вес. ч. морфолина, 5 вес. ч. поды и 6 вес. ч. едкого натра, к раствору прибавл ют в течение 1 час раствор из 21 вес. ч. меркаптобензтиазола в 12 вес. ч. воды и 6 вес. ч. едкого натри при одновременном пропускании газообразного хлора над поверхностью реакционной массы, поддержива температуру около 30°С.Example. Prepare a solution of 48 wt. including morpholine, 5 wt. h. and 6 wt. weight. including caustic soda, to the solution was added within 1 hour a solution of 21 wt. including mercaptobenzthiazole in 12 wt. including water and 6 wt. including sodium hydroxide while passing gaseous chlorine above the surface of the reaction mass, maintaining a temperature of about 30 ° C.
Конец реакции провер ют качественной реакцией на исчезновение лтеркаптобензоназола, например, с азотнокислым висмутом.The end of the reaction is checked by qualitative reaction to the disappearance of ltercaptobenzonazole, for example, with bismuth nitrate.
Выпавший сульфенамид отфильтровывают, промывают водой и сушат.Sulfenamide precipitated is filtered off, washed with water and dried.
Выход 96-990/0 (от теоретического), т. пл. 79-81°С. Избыточный ыорфолин реге ерируют из фильтрата и промывных вод.Output 96-990 / 0 (from theoretical), so pl. 79-81 ° C. Excessive chyorpholine is recovered from the filtrate and wash water.
