Description
РГзвестен способ получени хлорофоса, заключающийс во взаимодействии метанола с треххлористым фосфором и хлоралем в четыреххлористом углероде при температуре О- 60°С.The PH method is known for producing chlorophos, which consists in the interaction of methanol with phosphorus trichloride and chloral in carbon tetrachloride at a temperature of 0-60 ° C.
Предложенный способ отличаетс тем, что диметилфосфат подвергают взаимодействию с хлоральгидратом в присутствии стабилизатора основного характера - органических аминов , например триэтиламина. Процесс ведут при температуре до 60°С. Способ расшир ет сырьевую базу, а также дает возможность получить продукт с выходом не менее 90%.The proposed method is characterized in that dimethyl phosphate is reacted with chloral hydrate in the presence of a basic stabilizer, organic amines, for example triethylamine. The process is conducted at temperatures up to 60 ° C. The method expands the raw material base and also makes it possible to obtain a product with a yield of at least 90%.
Пример. Смесь 0,5 моль хлоральгидрата, 0,5 моль диметилфосфита и 1,5 мл триэтиламина нагревают до 60°С и при перемешивании выдерживают 1 час, после чего полученный сырец отпаривают при остаточном вакууме доExample. A mixture of 0.5 mol of chloral hydrate, 0.5 mol of dimethyl phosphite and 1.5 ml of triethylamine is heated to 60 ° C and kept under stirring for 1 hour, after which the resulting raw material is stripped under residual vacuum to
прекращени отгона. Из куба выгружают при 70°С 127 г хлорофоса с содержанием действующего начала 97%. Выход 100%-кого продукта в пересчете на диметилфосфористую кислоту не менее 90%,.stop distillation. 127 g of chlorophos with an active content of 97% is discharged from the cube at 70 ° С. The yield of 100% product in terms of dimethylphosphorous acid is not less than 90%.
