СПОСОБ ПОЛУЧЕНИЯ КИСЛЫХ ЦИКЛИЧЕСКИХ ФОСФИТОВMETHOD OF OBTAINING ACID CYCLIC PHOSPHITES
1one
Изобретение относитс к области химии фосфорорганических соединений, а именно к новому способу получени кислых циклических фосфитов общей формулыThe invention relates to the field of chemistry of organophosphorus compounds, namely to a new method for producing acidic cyclic phosphites of the general formula
, о н , he
где 41 - алкилен нормального или изостроени или фенилен, которые з л ютс реакционноспособными соединени ми и наход т применение в качестве полупродуктов фосфорорганического синтеза.where 41 is normal alkylene or iso-construction or phenylene, which is toxic to reactive compounds and finds use as an intermediate for organophosphorus synthesis.
Известен способ получени кислых циклических фосфитов ацидолиэом амидофосфитов 1.A known method for producing acid cyclic phosphites is acidolyamide amidophosphites 1.
Прототипом изобретени вл етс способ получени кислых циклических фосфитов в среде органического растворител в присутствии органических оснований 2.The prototype of the invention is a method for producing acidic cyclic phosphites in an organic solvent medium in the presence of organic bases 2.
Недостаток способа - использование акцептора хлористого водорода, больших количеств растворител , а также введение дополнительных операций , св занных с отделением сол нокислых оснований, и удалением растворител ..The disadvantage of this method is the use of a hydrogen chloride acceptor, large quantities of solvent, as well as the introduction of additional operations associated with the separation of hydrochloric acid bases and the removal of solvents ..
Цель изобретени - упрощение процесса получени кислых циклических фосфитов.The purpose of the invention is to simplify the process of obtaining acidic cyclic phosphites.
Это достигаетс тем, что циклический хлорфосфит подвергают взаимо действию с Н «триметилсилилацетамИ дом, желательно, при температуре 20 - . This is achieved by reacting cyclic chlorophosphite with H < 3 > trimethylsilylacetam and, preferably, at a temperature of 20 -.
Синтез ведут в колбе с нисход щим холодильником с отгонкой триметилхлорсилана при 100-140®С. Контр .оль за ходом реакции ведут„- по количеству выдел ющегос хлорси ана.Synthesis is carried out in a flask with a descending cooler with distilling off trimethylchlorosilane at 100-140 ° C. The control over the course of the reaction is carried out - by the amount of chlorine released.
В р де случаевf целевые продукты вл ютс кристаллическими веществами , они с количественным выходом образуютс при простом смешенин реагентов.In a number of cases, the target products are crystalline substances, they are formed in quantitative yield with simple mixing of the reagents.
Отличительным признаком способа вл етс использование И -трюйетилЬилилацетамида , который взаимодействует с циклическим хлорфосфитом в вышеуказанном режиме.A distinctive feature of the method is the use of AND -truyethyl or acetyl-amtamide, which reacts with cyclic chlorophosphite in the above mode.
