SU276958A1 - The method of obtaining organosilicon epoxy monomers aromatic - Google Patents

Description

The invention of OTHIXIHTCH for the synthesis of silicon organic epoxy monomers of the aromatic row of common formula

G /

I

where R is alkyl, and 1-3.

 The resulting monomers MotuT can be used to synthesize resins with high thermo-JQ

; stability

I A known method of producing these compounds is by adding silicon hydrides to an unsaturated of. -ox m in the presence of platinum catalysts, OAHH-JJ ko this method is multi-stage and not technological enough.

In order to simplify the process, it is proposed to prepare organosilicon epoxy monomers of the aromatic series with the action of silicon containing 1 aromatic hydrocarbons with epichlorohydrin in the presence of aluminum chloride) and as a catalyst, followed by dehydrochlorination of the chlorohydrines thus formed.

Example 1. In a reactor with a stirrer and a thermometer, 128 g of t-methyl, benzylsilane and 34.6 g of x-lorous nickel. The mixture is cooled to 0 ° C, and then 24 g of chlorohydrin glide are gradually added in a stream of dry nitrogen. At the end of the filing; The epichlorohydrin mixture is stirred at room temperature for another 3 hours and decomposed with water. The aqueous layer is separated from the org -

Claims of Invention A method for producing organosilicon epoxy monomers of an aromatic series by the interaction of crc ory; compounds with, N — oxides in the presence of a catalyst, followed by isolation of the target product by known methods, are distinguished by the fact that, in order to simplify the process, silicon-containing aromatic carbons (oi-oxides — epidorods) are used as scientific research institutes, and the chlorohydrin — the process lead in the presence of catalytic quantities of aluminum chloride i aluminum followed by dehydrochlorinated chlorhydrins. /
