Description

Существующий способ производства технического гексахлорциклогексана (гексахлорана) основан на фотохимическом хлорировании бензола . Получающийс  при этом гексахлоран содержит сравнительно незначительное количество Y-гексахлорциклогексана (10-12%).The existing method for the production of technical hexachlorocyclohexane (hexachlorane) is based on the photochemical chlorination of benzene. The resulting hexachlorane contains a comparatively small amount of Y-hexachlorocyclohexane (10-12%).

Описываемый способ в отличие от известного повышает содержапие 7-гексахлорциклогексана в продукте. Это достигаетс  тем, что хлорирование ведут при добавлении 1% борнилхлорида от веса бензола обычными приемами.The described method in contrast to the known increases the content of 7-hexachlorocyclohexane in the product. This is achieved by the fact that chlorination is carried out with the addition of 1% bornyl chloride by weight of benzene by conventional methods.

Пример. В реактор фотохимического хлорировани , работаюпип по непрерывной или периодической схеме, заливают бензол, содержащий 1% борнилхлорида. Хлорирование этого бензольного раствора газообразным хлором ведут при световом облучении реакционно среды ,и при 40-60° до удельного веса 1,2. Получающийс  бензольны раствор в дальнейщем подвергают прин тым в технолог и производства гексахлорана операц 1 м, т. е. не вошедший в реакцию бензол отгон ют вод ным паром, а остаток (плав гексахлорана) кристалл1 зу от и промывают водой. Борнилхлорид и проду ть его |Хлорирован   при отгонке бензола вод ным паром частично улетучиваютс  i собираютс  в конденсате, частично остаютс  в гексахлоране, усилива  его нсектисидные качества. Готовый продукт содержит 30-32% у-гекса.хлорциклогексана .Example. Benzene containing 1% of bornyl chloride is poured into the photochemical chlorination reactor, operating in a continuous or batch manner. Chlorination of this benzene solution with chlorine gas is carried out under light irradiation of the reaction medium, and at 40-60 ° to a specific weight of 1.2. The resulting benzene solution is subsequently subjected to 1 m of processors used in hexachloran production and operational, i.e., unreacted benzene is distilled off with water vapor, and the residue (melt of hexachlorane) is crystallized from and washed with water. Bornyl chloride and purge it | Chlorinated by distillation of benzene with water vapor partially evaporate and are collected in a condensate, partially remaining in hexachlorane, enhancing its insecticidal properties. The finished product contains 30-32% y-hexa.chlorocyclohexane.

Предмет изобретени Subject invention

Способ получени  гексахлорана фотохим 1ческим хлорированием бензола, отличающийс  тем, что, с целью повышени  содержани  в получающемс  гексахлоране т-гексахлорциклогексана, хлорирование ведут обычным способом, но при добавлении 1% борнилхлорида от веса бензола.The method for producing hexachlororane photochemically by 1 chlorination of benzene, characterized in that, in order to increase the content of t-hexachlorocyclohexane in the resulting hexachlorane, chlorination is carried out in the usual way, but with the addition of 1% bornyl chloride by weight of benzene.
