Description
Известный в промышленности способ получени гексахлорэтана основан на хлорировании дихлорэтана или аддитивном хлорировании пер (лорэтилена. Известно также получение гексахлор0утадиена путем пиролиза гексахло()бутана.The method of producing hexachloroethane known in the industry is based on the chlorination of dichloroethane or the additive chlorination of per (lorethylene). It is also known to obtain hexachlorotutadiene by pyrolysis of hexachlo () butane.
Предлагаемый способ одновременного получени гексахлорбутадиена н гекспхлорэтетпа путем пиролиза хлорпроизводных углеводородов отличлетс тем, что в качестве исходного хлорпроизводпого примен ют тетрахлорэтилси, который подверга-ют пиролизу при давлении 800- 1200 атм и температуре 300- 350° (в отсутствии катализаторов). Получаемые при этом продукты реакции состо т из примерно одинаковых количеств гекса.хлорэтана н гексахлорбутадиена (по 20-25 вес% ОТ загруженного тетрахлорэтилена), непрореагировавшего тетрахлорэтилена (около 50%) и смолистых веществ (до 3%); свободный хлор образуетс в весьма небольших количествах .The proposed method for the simultaneous production of hexachlorobutadiene and hexachloroethane by pyrolysis of chlorine derivatives of hydrocarbons is different in that tetrachloroethylsis is used as the initial chlorine production, which is pyrolyzed at a pressure of 800-1200 atm and a temperature of 300-350 ° (in the absence of catalysts). The resulting reaction products consist of approximately equal amounts of hexa.chloroethane n hexachlorobutadiene (20-25% by weight of loaded tetrachlorethylene), unreacted tetrachlorethylene (about 50%) and resinous substances (up to 3%); free chlorine is produced in very small amounts.
Разделение продуктов реакции производ т следующим образом.The separation of the reaction products is as follows.
Сначала при атмосферном давлении или в вакууме отгон ют непрореагировавший тетрахлорэтилен. Затем остаток фильтруют дл отделени от гексахлорэтана, после чего от фильтрата отгон ют, также при атмосферном или пониженном давлении , сначала смесь гексахлорэтана с гексахлорбутадиеном, а затем один гексахлорбутадиен. Выделение гексахлорэтана из смеси его с гексахлорбутадиеном производ т путемг вымораживани первого охлаждением смеси до-15,-20.Unreacted tetrachlorethylene is distilled off at atmospheric pressure or in vacuum. The residue is then filtered to separate it from hexachloroethane, after which the mixture is distilled off, also under atmospheric or reduced pressure, first with a mixture of hexachloroethane and hexachlorobutadiene, and then with one hexachlorobutadiene. The extraction of hexachloroethane from its mixture with hexachlorobutadiene is carried out by freezing the first one by cooling the mixture to -15, -20.
