где п - целое число 3 или 4.where n is an integer 3 or 4.
Эти соединени могут найти применение в качестве физиологически активных веществ , антипиренов, комплексообразователей , пластификаторов, присадок к смазочным маслам, а также в качестве полупродуктов фосфорорганического синтеза.These compounds can be used as physiologically active substances, flame retardants, complexing agents, plasticizers, lubricant additives, as well as organic phosphorus intermediates.
Известен способ получени 0-(2-хлорэтил ) -алкоксиметилфосфонатов взаимодействием этиленхлорфосфита с диалкилформалем при 110-160°С 1.A known method for producing 0- (2-chloroethyl) -alkoxymethylphosphonates by reacting ethylene chlorophosphite with dialkylformal at 110-160 ° C 1.
Известен.также способ получени неопентилен - алкилфосфонатов нагреванием- неопентилен-алкилфосфитов до 100-250°С в присутствии катализатора - йодистого или бромистого алкила 2.A known method of producing neopentylene alkylphosphonates by heating neopentylene alkyl phosphites to 100-250 ° C in the presence of a catalyst, iodide or alkyl bromide 2.
Однако способ получени 0,0-неопентилен-ш-хлоралкоксиметилфосфонатов , а также сами соединени в литературе не описаны и вл ютс новыми.However, the process for the preparation of 0,0-neopentylene-w-chloroalkoxymethylphosphonates, as well as the compounds themselves, are not described in the literature and are new.
Целью изобретени вл етс разработка способа получени 0,0-неопентилен-ш-хлоралкоксиметилфосфонатов .The aim of the invention is to develop a process for the preparation of 0,0-neopentylene-w-chloroalkoxymethylphosphonates.
Поставленна цель достигаетс описываемым способом получени 0,0-неопентиленw-хлоралкоксиметилфосфонатов формулы (I), который заключаетс в том, что неопентиленхлорфосфит подвергают взаимодействию с формалем соответствующего диола JQ при нагревании до 120-150°С.This goal is achieved by the described method for the preparation of 0,0-neopentylen-w-chloroalkoxymethylphosphonates of formula (I), which consists in reacting neopentylen-chlorophosphite with the formal of the corresponding diol JQ when heated to 120-150 ° C.
Процесс ведут при атмосферном или повышенном давлении. Описываемый способ вл етс новым, характеризуетс простотой и доступностью исходных реагентов и осуществл етс без разрыва алкиленового The process is conducted at atmospheric or elevated pressure. The described method is new, is characterized by simplicity and availability of initial reagents and is carried out without breaking the alkylene one.
15 цикла в отличие от получени 0-(2-хлорэтил ) -алкоксиметилфосфонатов.15 cycles in contrast to the production of 0- (2-chloroethyl) alkoxymethylphosphonates.
Целевые продукты выдел ют перегонкой в вакууме. Они представл ют собой масл нистые жидкости, растворимые в органиче20 ских растворител х и не растворимые в воде.The desired products are recovered by vacuum distillation. They are oily liquids soluble in organic solvents and insoluble in water.
Необходимые дл реализации описываемого способа полупродукты вполне доступны и могут производитьс в промышленном The intermediate products required for the implementation of the described method are quite accessible and can be produced in industrial
