Description
вавшегос 1,1-ДИХлорэтана. Перед началом опыта в реактор загружают 1,1-дихлорэтан и катализатор, реактор термостатируют и включают подачу исходных газов. Хлористый водород и винилхлорид подают в смеситель и затем через барботер - в нижнюю часть реактора. Образующийс в результате реакции 1,1-дихлорэтан уноситс из реактора избыточным хлористым водородом и улавливаетс в ловуи1ках. Непрореагировавший хлористый водород поглощают водой в абсорбционной колонке. Скон.:1.енсировавщийс 1,дихлорэтан и реакционный раствор из реактора анализируют хроматографически. Количество смолы в реакционном растворе определ ют после отгонки 1,1-дихлорэтана.all-1,1-dichloroethane. Before the start of the experiment, 1,1-dichloroethane and the catalyst are loaded into the reactor, the reactor is thermostatic and the feed gas is turned on. Hydrogen chloride and vinyl chloride are fed to the mixer and then through the sparger to the bottom of the reactor. The resulting 1,1-dichloroethane resulting from the reaction is carried away from the reactor by excess hydrogen chloride and trapped in traps. Unreacted hydrogen chloride is absorbed by water in an absorption column. Scan: 1. Sensing 1, dichloroethane and the reaction solution from the reactor are analyzed by chromatography. The amount of resin in the reaction solution is determined after distilling 1,1-dichloroethane.
Результаты опытов по гидрохлорированию винилхлорида в присутствии хлористого алюмини при различных параметрах процесса, времени реакции, температуре и соотношении исходных газов приведены в таблице. В этой же таблице дл сравнени приведены данные по гидрохлорированию винилхлорида в услови х известного способа.The results of the experiments on the hydrochlorination of vinyl chloride in the presence of aluminum chloride at different parameters of the process, reaction time, temperature and the ratio of the source gases are given in the table. In the same table for comparison, data on the hydrochlorination of vinyl chloride under the conditions of a known method are given.
Предмет изобретени Subject invention
Способ получени 1,1-дихлорэтана гидрохлорированием винилхлорида в жидкой фазе хлористым водородом в присутствии катализатора-хлорида металла с последующим выделением целевого цродукта известными приемами , отличающийс тем, что, с целью уменьщени образовани смолообразных продуктов реакции и усовершенствовани технологического процесса, последний ведут при температуре не выще 22°С и мол рном соотношении винилхлорида и хлористого водорода 1 : 3,5-4,5.The method of producing 1,1-dichloroethane by hydrochlorinating vinyl chloride in the liquid phase with hydrogen chloride in the presence of a metal-chloride catalyst, followed by separation of the desired product by known methods, characterized in that the temperature of the resinous reaction products is reduced and the process is improved above 22 ° C and a molar ratio of vinyl chloride to hydrogen chloride is 1: 3.5–4.5.
