(54) СПОСОБ ПОЛУЧЕНИЯ ДИАРИЛ-2-ХЛОРАЛКИЛФОСФАТОВ(54) METHOD OF OBTAINING DIARYL-2-CHLORALKYL PHOSPHATES
1one
Изобретение относитс к химии эфиров фосфорной кислоты, конкретно к новому способу получени диарил-2-хлоралкилфосфатов общей формулыThis invention relates to the chemistry of phosphoric acid esters, specifically to a new process for the preparation of diaryl-2-chloroalkyl phosphates of the general formula
{АгоЦок О{Agotzok O
где Аг - ароматический радикал, R - 2-хлоралкильный радикал.where Ar is an aromatic radical, R is a 2-chloroalkyl radical.
Эти соединени обладают фунгицидной, бактерицидной, инсектицидной и акарицидной активностью и наход т или могут найти применение дл борьбы с болезн ми и вредител ми сельско-хоз йственных растений. Кроме того, они представл ют интерес дл изучени в качестве антивоспламенительных добавок к органическим материалам, присадок к топливу и смазочным маслам.These compounds possess fungicidal, bactericidal, insecticidal and acaricidal activity and are or can be used to combat diseases and pests of agricultural plants. In addition, they are of interest for studying as anti-inflammatory additives to organic materials, fuel additives and lubricants.
Известны способы получени диарил-2хлоралкилфосфатов реакцией 2-хлоралкилдихлорфосфатов с фенолами или диарилхлорфосфатов с алкиленхлоргидринами в присутствии третичных аминов в качестве акцептора хлористого водорода 1, 2. Этим способам присущи недостатки, характерные дл всех акцепторных способов получени эфиров кислот фосфора и св занные с трудност ми удалени хлористоводородной соли акцептора и регенерации акцептора.There are known methods for producing diaryl-2-chloroalkyl phosphates by reacting 2-chloroalkyldichlorophosphates with phenols or diaryl-chlorophosphates with alkylene chlorohydrins in the presence of tertiary amines as a source of hydrogen chloride, 2, 2, 2, 2, 2, 2-chloroalkyl chlorohydrin phosphates, and the same methods that are used in manganese the hydrochloride salt of the acceptor and the regeneration of the acceptor.
Более рационален способ получени диарил-2-хлоралкилфосфатов взаимодействием диарилфосфитов с четыреххлористым углеродом и окис ми алкиленов при температуре около 100°С 3. Однако выход продукта реакции очень низок.A more rational method is to obtain diaryl-2-chloroalkyl phosphates by reacting diaryl phosphites with carbon tetrachloride and alkylene oxides at a temperature of about 100 ° C. However, the yield of the reaction product is very low.
Одними из наиболее простых и рациональных способов синтеза триорганофосфатов вл ютс способы, основанные на окислении соответствующих триорганофосфитов, если они доступны. Однако известно, что жирноароматические фосфиты кислородом не окисл ютс 4.One of the most simple and rational methods for the synthesis of triorganophosphates is based on the oxidation of the corresponding triorganophosphites, if available. However, it is known that fatty-aromatic phosphites are not oxidized by oxygen 4.
Цель изобретени - повыщение выхода продукта.The purpose of the invention is to increase the yield of the product.
Достигаетс это предлагаемым способом получени диарил-2-хлоралкилфосфатов, основанном на окислении диарил-2-хлоралкилфосфитов .This is achieved by the proposed method for the preparation of diaryl-2-chloroalkyl phosphates, based on the oxidation of diaryl-2-chloroalkyl phosphites.
Согласно изобретению, диарил-2-хлоралкилфосфиты окисл ют перекисью водорода в двухфазной щелочно-органической, например щелочно-бензольной, среде в присутствии каталитических количеств четвертичного аммонийгалогенида, например триэтилбензиламмонийхлорида , при температуре 20-30°С. Процесс провод т прибавлением водного раствора перекиси водорода к интенсивноAccording to the invention, diaryl-2-chloroalkyl phosphites are oxidized with hydrogen peroxide in a two-phase alkali-organic, e.g. alkaline-benzene, medium in the presence of catalytic amounts of a quaternary ammonium halide, for example triethylbenzylammonium chloride, at a temperature of 20-30 ° C. The process is carried out by adding an aqueous solution of hydrogen peroxide to an intensive
