Description
Предлагают способ получени виниловых зфиров 0,0-дналкил-О-оксиалкилтиофосфатов, состо щий в том, что диалкилфинилоксиалкилфосфат подвергают взанмодейств 1Ю с серой с последующим выделением целевого продукта известпым способом.A method is proposed for the preparation of the vinyl esters of 0,0-dinalkyl-O-hydroxyalkyl thiophosphates, in which the dialkyl-phenyloxyalkyl phosphate is exposed to sulfur with sulfur followed by isolation of the desired product by the lime method.
Пример 1. Синтез О.О-диэтил-О-винилоксиэтилтиофосфата . К 8,0 г диэтилвипилоксиэтилфосфита прибавл ют 1,2 г порошковой серы. Происходгг экзотермическа реакци , в результате которой темнература поднимаетс до 120°С, а сера полностью раствор етс . Полученный прозрачный слегка желтоватый продукт достаточно чист дл осуидествлепи превращений по винильной группе. Дл целей полимеризации продукт очищают перегонкой . Получают 9,1 г (выход 99,б5/о от теоретического ) 0,0-диэтил-О-вииилоксиэтилтиофосфата; т. кип. 80°С, по 1,4667; df 1,1097; MRo 60,04; MRo 60,42.Example 1. Synthesis of OO-diethyl-O-vinyloxyethyl thiophosphate. To 8.0 g of diethylvipyloxyethylphosphite was added 1.2 g of powdered sulfur. The exothermic reaction takes place, as a result of which the temneture rises to 120 ° C and the sulfur completely dissolves. The resulting clear, slightly yellowish product is sufficiently pure to transform into the vinyl group. For polymerization purposes, the product is purified by distillation. 9.1 g are obtained (yield 99, b5 / o from the theoretical) 0,0-diethyl-O-viiiyloxyethyl thiophosphate; m.p. 80 ° C, 1.4667 each; df 1.1097; MRo 60.04; MRo 60.42.
