Изобретение относитс к -химии кремнийсодержащих соединений, а именно к улучшенному способу получени oi -окисей кремнийсодержащих олефи-. нов.This invention relates to the chemistry of silicon-containing compounds, namely to an improved process for the preparation of oi-oxides of silicon-containing olefins. new
ОС -Окиси кремнийсодержащих олефинов используют в качестве исходных веществ дл синтеза кремнийорганических полимеров, о&ладающих высокой термостойкостью и хорошими механическими , диэлектрическими свойствами.OS-Oxides of silicon-containing olefins are used as starting materials for the synthesis of organosilicon polymers, with a high temperature resistance and good mechanical, dielectric properties.
Известен способ получени х -окисей кремнийсодержащих олефинов /взаимодействием алкокси(ацатокси)силанов или галоидсиланов с глицидолом flj. Этот способ требует применени довольно высоких температур.A known method for producing x-oxides of silicon-containing olefins / by reacting alkoxy (atsatoxy) silanes or halo-silanes with glycidol flj. This method requires the use of rather high temperatures.
Известен также способ получени об -окисей кремнийсодержащих олефиноб окислением кремнийсодержащих олефинов органическими надкислотами в среде органического растворител при Р-20С 2.There is also known a method for producing o-oxides of silicon-containing olefins by oxidizing silicon-containing olefins with organic peracids in an organic solvent medium at P-20C 2.
Однако выход целевого продукта не превышает 60%, Кроме того, процесс длителен (в зависимости от олефйна и примен емой надкислоты от нескольких часов до нескольких суток).However, the yield of the target product does not exceed 60%. In addition, the process is lengthy (depending on the olefin and the peracid used, from several hours to several days).
Целью изобретени вл етс повышение выхода продукта и ускорение процесса.The aim of the invention is to increase the yield of the product and accelerate the process.
Указанна цель достигаетс тем, что окисление кремнийсодержащих олефинов провод т органическими гидроперекис ми например алкил-, аралкилили алкоксигидроперекис ми, в присутствии каталитических количеств соединений молибдена или ванади ,например гексакарбонила молибдена Mo(CO) пентахлорида молибдена МоС , ацетилацетоната ванади .This goal is achieved by the oxidation of silicon-containing olefins by organic hydroperoxides, for example alkyl-, aralkyl or alkoxyhydroperexides, in the presence of catalytic amounts of molybdenum or vanadium compounds, for example, molybdenum hexacarbonyl Mo (CO) molybdenum pentachloride MoC, acetylacetone vanadium.
Процесс провод т в среде органического растворител , например бензола , желательно при температуре 2080 С ..- The process is carried out in the medium of an organic solvent, for example benzene, preferably at a temperature of 2080 ° C ..-
Окисление заканчиваетс в течение 2-4 ч. Целевые продукты выдел ют известными приемами. Выход 70-84%.The oxidation is completed within 2-4 hours. The desired products are recovered by known techniques. The yield of 70-84%.
Пример. К раствору 4,1 Г (6,029 моль) триметилсилил-2-пентена в 30 мл сухого бензола прибавл ют 0,05 г Мо(СО) и 3,57 г (0,035 моль) гидроперекиси трет-амила. Смесь выдерживают 3 ч при . Реакционную массу промывают водой, сушат сульфат натри , бензол отгон ют в вакууме, создаваемом водоструйным насосом. Вакуумной разгонкой выдел ют 3,3 г (74.%)Example. To a solution of 4.1 g (6.029 mol) of trimethylsilyl-2-pentene in 30 ml of dry benzene, 0.05 g of Mo (CO) and 3.57 g (0.035 mol) of tert-amyl hydroperoxide were added. The mixture is kept for 3 h at. The reaction mass is washed with water, dried sodium sulfate, the benzene is distilled off in a vacuum, created by a water-jet pump. 3.3 g (74.%) were isolated by vacuum distillation.
