Description
Изобретение касаетс способа получени трихлорфосфазоацилов.This invention relates to a process for the preparation of trichlorophosphazoacyls.
Известен способ получени трихлорфосфазоацилов взаимодействием амидов кислот с п тихлористым фосфором.A method of producing trichlorophosphazoacyls by reacting acid amides with phosphorus penichloride is known.
Предлагаемый способ отличаетс от известного тем, что амиды кислот подвергают взаимодействию с треххлористым фосфором и хлором в бензоле или четыреххлористом углероде при нагревании до 70-80°С.The proposed method differs from that in that the amides of the acids are reacted with phosphorus trichloride and chlorine in benzene or carbon tetrachloride when heated to 70-80 ° C.
Применение треххлористого фосфора упрощает процесс, что делает его пригодным дл промышленного использовани , а также повышает выход целевого продукта.The use of phosphorus trichloride simplifies the process, making it suitable for industrial use, and also increases the yield of the target product.
Пример. Смесь 0,1 г-моль амида кислоты , 0,11 г моль треххлористого фосфора н 80 мл бензола или четыреххлористого углерода нагревают при перемешивании до 70-Example. A mixture of 0.1 g mol of amide acid, 0.11 g mol of phosphorus trichloride n 80 ml of benzene or carbon tetrachloride is heated with stirring to 70-
85°С и пропускают хлор до полного раствореии амида (30-35 1шн).85 ° C and chlorine is passed until the amide is completely dissolved (30-35 1 shn).
Растворитель отгон ют в вакууме. В остатке получают трихлорфосфазоацил.The solvent is distilled off in vacuo. Trichlorophosphazoacyl is obtained in the residue.
