Description
Известен способ получени хлористого винила хлорированием этилена в присутствии хлористого винила при температуре 400- 450°С, соотношении хлор - этилен - хлорвинил , равном 1 : 2,8 : 2,2, и времени реакции 5 сек. Выход продукта составл ет 93-98%.A known method of producing vinyl chloride by chlorination of ethylene in the presence of vinyl chloride at a temperature of 400-450 ° C, a ratio of chlorine to ethylene-chlorovinyl is 1: 2.8: 2.2, and the reaction time is 5 seconds. The product yield is 93-98%.
Цель изобретени - упростить процесс. Достигаетс это тем, что хлорирование этилена ведут в присутсгвии вод ного пара, что исключает возможность сажеобразовани и необходимость циркул ции непрореагировавших и избыточных газов, а также сокращает врем реакции, аппаратурное оформление значительно упрощаетс .The purpose of the invention is to simplify the process. This is achieved by the fact that the chlorination of ethylene is carried out in the presence of water vapor, which eliminates the possibility of soot formation and the need for the circulation of unreacted and excess gases, and also shortens the reaction time, the instrumentation is greatly simplified.
Способ заключаетс в хлорировании этилена в присутствии вод ного пара. Соотношение этилен - хлор - вод ной пар равно 1:1: 4- 5. Выход продукта составл ет 95%.The method involves the chlorination of ethylene in the presence of water vapor. The ratio of ethylene to chlorine water vapor is 1: 1: 4-5. The product yield is 95%.
Пример. В реакционный аппарат, представл ющий собой полую трубку, снабженную электрообогревом, ввод т предварительно подогретый до температуры реакции этилен и смесь хлора с вод ным паром. ТемпературуExample. Preheated to the reaction temperature ethylene and a mixture of chlorine with steam are introduced into the reaction apparatus, which is a hollow tube, equipped with electrical heating. Temperature
реакции поддерживают в пределах 400- 450°С. Мол рное соотношение реагентов этилен- хлор - вод ной пар 1:1:4,5, врем пребывани смеси в зоне реакции 2-3 сек.the reaction is maintained within 400-450 ° C. The molar ratio of the reactants ethylene chlorine to water vapor is 1: 1: 4.5, the residence time of the mixture in the reaction zone is 2-3 seconds.
Реакционные газы на выходе из хлоратора проход т холодильник, где коиденсируетс вод ной пар и образуетс 25-28%-на сол на кислота. Затем газы промывают раствором щелочи, сушат хлористым кальцием и едким кали и конденсируют. Выход хлористого винила составл ет 90-95% от вступившего в реакцию хлора или этилена. Конверси хлора за проход составл ет lOOVoПредмет изобретени The reaction gases at the outlet of the chlorinator pass through a cooler where water vapor is co-sensitized and 25-28% hydrochloric acid is formed. Then the gases are washed with alkali solution, dried with calcium chloride and potassium hydroxide and condensed. The yield of vinyl chloride is 90-95% of the chlorine or ethylene reacted. The chlorine conversion per pass is lOOVo.
