1. Способ получения диалкилфосфитов общей формулы
(RO)2Р(O)H,
где R - незамещенный или замещенный алкил или аралкил,
с использованием фосфортрихлорида и соответствующего алканола, отличающийся тем, что, с целью повышения выхода целевых веществ и рационального использования реагентов, фосфортрихлорид подвергают взаимодействию с трет-бутанолом с последующей обработкой продуктов реакции алканолом.1. The method of obtaining dialkylphosphites of General formula
(RO) 2 P (O) H,
where R is unsubstituted or substituted alkyl or aralkyl,
using phosphorotrichloride and the corresponding alkanol, characterized in that, in order to increase the yield of target substances and the rational use of reagents, phosphorotrichloride is subjected to interaction with tert-butanol, followed by treatment of the reaction products with alkanol. 2. Способ по п. 1, отличающийся тем, что фосфортрихлорид, трет-бутанол и алканол берут в молярных соотношениях 1:1:2 соответственно. 2. The method according to p. 1, characterized in that phosphorotrichloride, tert-butanol and alkanol are taken in molar ratios of 1: 1: 2, respectively. 3. Способ по п. 1, отличающийся тем, что процесс ведут в среде трет-бутилхлорида и завершают кипячением реакционной массы до прекращения выделения хлороводорода. 3. The method according to p. 1, characterized in that the process is conducted in an environment of tert-butyl chloride and is completed by boiling the reaction mass until the termination of the release of hydrogen chloride.
