Description
Известен способ получени эфнров алкилхлорфосфинистых кислот путем взаимодействи алкиленоксндов с алкнлдихлорфосфинами.A known method for producing alkyl chlorophosphinic acid esters by reacting alkylene oxides with alkynyl chlorophosphines.
Дл расширени ассортимента эфиров алкилхлорфосфинистых кислот предлагаетс способ получени последних, заключающийс в том, что алкнлднхлорфосфины подвергают взаимодействию со спиртами в присутствии оснований.In order to expand the range of alkyl chlorophosphinic acid esters, a method is proposed for preparing the latter, in which the alknold chlorophosphines are reacted with alcohols in the presence of bases.
Способ осуществл ют следуюш,нм образом. Раствор алкилднхлорфосфнна в инертном растворителе при охлаждении перемешивают с эквимолекул рными количествами спирта и диэтиланилина (или другого инертного растворител ). Осадок хлоргидрата основани отфильтровывают и в вакууме дтгон ют растворитель .The method is carried out in the following, nm manner. The solution of alkyl dichlorophosphine in an inert solvent is stirred with cooling with equimolecular amounts of alcohol and diethylaniline (or another inert solvent). The base hydrochloride precipitate is filtered off and the solvent is distilled under vacuum.
Пример. В трехгорлую колбу помета гот 0,2 мол алкилдихлорфосфнна в 200 мл сухого инертного растворител . При перемешнпанни и до 0°С медленно прилипают смесь экзимол рных колнчеств спирта и днэтнланнлнна (или другого нмертного растворител ), затем реакционную смесь псремешивают в течение 2 часов. Осадок хлоргидрата основани отфильтровывают и в вакууме отгон ют растворитель. Остаток перегон ют в вакууме . Все операции провод т в атмосфере азота. Выделенные эфиры алкнлхлорфосфиннстых кислот и их физические константы приведены в таблице. Предмет изобретени Опособ получени эфиров алкилхлорфосфинистых кислот на основе алкилдихлорфосфинов , отличающийс тем, что, с целью расширени ассортимента эфиров, алкилдихлорфосфины подвергают взаимодействию со спиртами в присутствии оснований.Example. In a three-necked litter flask gota 0.2 mol of alkyl dichlorophosphine in 200 ml of dry inert solvent. With stirring and to 0 ° C, a mixture of eximolar alcohol and danethnolnn (or other deadly solvent) slowly adheres, then the reaction mixture is stirred for 2 hours. The base hydrochloride precipitate is filtered off and the solvent is distilled off in vacuo. The residue is distilled in vacuo. All operations are carried out in a nitrogen atmosphere. The selected esters of alkyl chlorophosphine acids and their physical constants are listed in the table. A method for producing alkyl chlorophosphinic acid esters based on alkyl dichlorophosphines, characterized in that, in order to expand the range of esters, alkyl dichlorophosphines are reacted with alcohols in the presence of bases.
