Description
Известен способ получени диалкилхлорфосфатов взаимолействием.хлора или хлористого сульфурила с диалкилфосфитами.A known method of producing dialkyl chlorophosphates by the mutual interaction of chlorine or sulfuryl chloride with dialkyl phosphites.
При осуществлении способа необходимо применение абсолютно сухих реагентов и тщательной защиты от влаги, так как в противном случае образуютс кислые фосфаты, которые разлагают целевые продукты.In carrying out the method, it is necessary to use absolutely dry reagents and careful protection against moisture, since otherwise acidic phosphates are formed, which decompose the target products.
Дл повышени выхода целевого продукта предлагаетс массу после хлорировани обрабатывать реагентами, способными превраа,ать кислые фосфаты в соответстпуюга .ие хлорангидриды, например тионилхлоридом , треххлорисгым фосчфором и хлором, фосгеном, н тихлористым фосфором. Эти реагенты добавл ют в количестве 0,01 - ОЛ моль на 1 ноль фосфита.To increase the yield of the target product, it is proposed to treat the mass after chlorination with reagents capable of converting acidic phosphates to appropriate chlorides, for example, thionyl chloride, trichlorine phosphorus and chlorine, phosphine, and phosphorus chloride. These reagents are added in an amount of 0.01 to OL mol per 1 zero of phosphite.
Пример 1. К 02 моль ;и1бутилфосфита при перемешивании, охлаждении и непрерывном продувании сухого воз;г.уха прибавл ют по капл м 0,22 моль хлористого сульфурил., поддержива температуру реакционной массы в пределах О-5°С. Затем в емесь при перемешивании барботируют 002 моль фосгена, выдерживают при 20°С 3-5 час, снова продувают в течение часа воздух н нерегоикой выдел ют дибутилхлорфосфат с т. кип. 125-127С (10 выход 96% теопетического.Example 1. To 02 mol; i1butylphosphite with stirring, cooling and continuous blowing of dry air, a drop of 0.22 mol of sulfuryl chloride is added dropwise, keeping the temperature of the reaction mass in the range of -5 ° C. Then, 002 mol of phosgene is bubbled into the mixture with stirring, kept at 20 ° C for 3-5 hours, the dibutyl chlorophosphate is recovered from the boil over an hour again, and the boil is stirred. 125-127С (10 is the yield of 96% of theopetic.

В тех же услови х без обработки фосгеном дибутилхлорфосфат получен с выходом УЗо/о. Пример 2. В 0,2 моль дибутилфосфита при перемешивании и охлаждении барботируют хлор до по влени желтой окраски, поддержива температуру не выше 5°С. Затем к смест прибавл ют 0,015 моль треххлористого фосфора и снова хлорируют в тех же усло;л-1 х до желтой окраски. Температуру смесн довод т до компатиой, основную массу хлористого водорода удал ют продуванием сухого поздуха и перегонкой выдел ют дибутилхлорфосфат с т. кип. 127-129°С (11 мм) 1,ыход, теоретического.Under the same conditions, without dibutyl chlorophosphate treatment with phosgene, it was obtained with a yield of UZO / o. Example 2. 0.2 mole of dibutylphosphite is bubbled with stirring and cooling until a yellow color appears, maintaining the temperature not higher than 5 ° C. Then, 0.015 moles of phosphorus trichloride are added to the displacements and again chlorinated under the same conditions; l -1 x to a yellow color. The temperature of the mixture is adjusted to compati, the bulk of the hydrogen chloride is removed by blowing dry dry and the dibutyl chlorophosphate is boiled off with boiling water. 127-129 ° С (11 mm) 1, yield, theoretical.
В а ;алогичных услови х без обработки треххлористым фосфором и хлором дибутилхлорфОсфат нолучеп с выходом .Under aa; illogical conditions, without treatment with phosphorus trichloride and chlorine, dibutylchlorophosphate does not get worse with yield.
Пример 3. Раствор 0., 15 моль дибутилфосфита в двукратном объеме невысушенного хлороформа обрабатывают 0,17 моль хлористого сульоЬурила, а затем 0,015 моль хлористого тиоцила в услови х примера 1.Example 3. Solution of 0., 15 mol of dibutyl phosphite in two times the volume of undried chloroform is treated with 0.17 mol of sulburyl chloride, and then 0.015 mol of thiocyl chloride under the conditions of example 1.
