Abstract

Ишда симм-дихлорэтан (1,2-дихлорэтан)дан водород хлориднинг ажралиб чиқиш реакциясида турли катализаторларнинг фаоллиги ва селективлиги ҳақидаги маълумотлар келтирилди. Экспериментал тадқиқотлар натижасида симм-дихлорэтан (1,2-дихлорэтансинтези жараёнини моделлаш учун унинг асосий кинетик параметрлари аниқландиКинетик тадқиқотлар 300-350 оC ҳарорат оралиғида, идеал жой алмаштирувчи, оқимли ўт ўтказгичда ўтказилди, унда реакция симм-дихлорэтан (1,2-дихлорэтан)  нинг 70%дан кўп бўлмаган конверсияси билан давом этди.
