Description
3 Предмет изобретени 1. Способ получени высших диалкилфосфитов взаимодействием высшего спирта с производным фосфористой кислоты, отличаю-5 щ и и с тем, что, с целью упрощени процесса , в качестве производного фосфористой кислоты используют продукты взаимодействи 4 треххлористого фосфора с метанолом при мольном соотношении , полученные при кип чении реакционной смеси, 2. Способ но п. 1, отличающийс тем, что процесс провод т е органическом растворителе , например ксилоле, при азеотропной отгонке воды.3 The subject matter of the invention 1. A method of producing higher dialkylphosphites by reacting a higher alcohol with a phosphorous acid derivative, distinguishes-5 y and in that, in order to simplify the process, the products of the interaction of 4 phosphorous phosphorus with methanol at a mole ratio obtained by boiling the reaction mixture; 2. Method of claim 1, characterized in that the process is carried out with an organic solvent, for example xylene, with azeotropic distillation of water.
