Это соединение используетс дл производства фосфорорганических термостабилизаторов полимеров и огнестойких добавок к различным веществам.This compound is used to produce organophosphorus thermostabilizers for polymers and flame retardants for various substances.
Известен способ получени трис-(2-хлорэтил )-фосфита взаимодействием треххлористого фосфора с окисью этилена; про1дукт образуетс с высоким выходом, но почти неизменно содержит относительноA known method for producing tris- (2-chloroethyl) phosphite by reacting phosphorus trichloride with ethylene oxide; The product is formed with a high yield, but almost invariably contains relatively
высокое количество (более 5%) фосфонастов в качестве побочных продуктов реакции . Эти примеси трудно отделить от трис (2-хлорэтил)-фосфита, поэтому они остаютс и в продуктах переработки, используемых в промышленности, и оказывают неблагопри тное действие на свойства этих продуктов.high amount (more than 5%) of phosphonasts as by-products of the reaction. These impurities are difficult to separate from tris (2-chloroethyl) phosphite, therefore they remain in the processed products used in industry and have an adverse effect on the properties of these products.
С целью повышени чистоты продукта ПJpoцecc взаимодействи треххлористого фосIn order to increase the purity of the product PJpocecc, the interaction of phosphorus trichloride
фора с окисью этилена провод т в среде дихлорэтана. Этот растворитель позвол ет понизить содержание побочных продуктов в трис-(2-хлорэтил)-фосфата до уровн ниже 5%.The ethylene oxide cortice is carried out in dichloroethane. This solvent allows the content of by-products in Tris (2-chloroethyl) phosphate to be reduced to a level below 5%.
Реагенты ввод т обычно в стехиометрическом количестве но можно примен ть небольшой избыток или недостаток окиси этилена. Реакци лучше всего идет при температуре, не превышающей 45 С.The reagents are usually introduced in stoichiometric amounts, but a slight excess or deficiency of ethylene oxide can be used. The reaction goes best at a temperature not exceeding 45 C.
Процесс желательно проводить путем растворени треххлористого фосфора в дихлорэтане , затем постепенно добавл к нему окись этилена. Последнюю можно вводить в виде раствора в дихлорэтане,The process is preferably carried out by dissolving phosphorus trichloride in dichloroethane, then gradually adding ethylene oxide to it. The latter can be introduced in the form of a solution in dichloroethane,
Добавление окиси этилена должно производитьс быстро и позвол ть поддерживать температуру реакционной среды в желаемых пределах. Предпочтительно заканчивать добавление окиси этилена не больше п ти часов, лучше всего не дольше одного часа.The addition of ethylene oxide should be carried out quickly and keep the temperature of the reaction medium within the desired limits. It is preferable to finish adding ethylene oxide for no more than five hours, preferably no longer than one hour.
Дихлорэтан можно добавл ть в любом количестве, однако лучше от 50 до 10ОО вес. ч. на каждые 1ОО вес. ч. общего коDichloroethane can be added in any amount, however, preferably from 50 to 10OO weight. hours for every 1OO weight. h. general co
