Description
Известен способ получени диметилдихлорсилана взаимодействием кремнемедного сплава с хлористым метилом с применением в качестве промотора сурьмы и выходом щелевого продукта 48-55%.A known method for producing dimethyldichlorosilane by the interaction of a silicon-copper alloy with methyl chloride using antimony as a promoter and a gap yield of 48-55%.
Предложенный способ отличаетс от известного применением в качестве промотора мышь ка, что дает возможность иовысить выход целевого продукта на 10% при одновременном увеличении производительности до 140-180 г/час с 1 кг сплава и снижени температуры синтеза до 290-310°.The proposed method differs from the known use as a mouse promoter, which makes it possible to improve the yield of the target product by 10% while simultaneously increasing the productivity to 140-180 g / hour with 1 kg of alloy and lowering the synthesis temperature to 290-310 °.
Предлагаемый способ получени диметилдихлорсилана заключаетс во взаимодействии кремнемедного сплава с хлористым метилом в течение 8,5 час при температуре 290-310° и применении в качестве промотора мышь ка в количестве 0,1-1,0%.The proposed method for the preparation of dimethyldichlorosilane consists in the interaction of a silicon-copper alloy with methyl chloride for 8.5 hours at a temperature of 290–310 ° and using a mouse in an amount of 0.1-1.0% as a promoter.
Пример. В реактор диаметром 50 мм загружают 150 г порошка кремнемедного сплава состава: Си - 10%, As - 0,16%, остальное-Si. При взаимодействии с хлористым метилом в течение 8,5 час при температуре 290-310° получено 140 г смеси метилхлорсиланов следуюш.его состава: метилдихлорсилан - 68%, метилтрихлорсилан - 28,4%, триметилхлорсилан - 3,0%, четыреххлористый кремний - 0,8%, диметилхлорсилан - 1,3%, трихлорсилан - 0,5%.Example. Into the reactor with a diameter of 50 mm load 150 g of a powder of a siliceous alloy of composition: Cu - 10%, As - 0.16%, the rest is Si. When interacting with methyl chloride for 8.5 hours at a temperature of 290-310 °, 140 g of a mixture of methylchlorosilanes were obtained following composition: methyldichlorosilane - 68%, methyltrichlorosilane - 28.4%, trimethylchlorosilane - 3.0%, silicon tetrachloride - 0 , 8%, dimethylchlorosilane - 1.3%, trichlorosilane - 0.5%.
По заключению о промышленной полезности способ после испытани в заводских услови х рекомендуетс дл Внедрени в производство.According to the industrial utility, the method after factory testing is recommended for the introduction into production.
