Abstract

Способ получения оксида пропилена из пероксида водорода и пропилена в растворителе - метаноле при температуре 20-70°С на гетерогенном титан-силикалитном катализаторе в двухстадийном синтезе с промежуточной отгонкой оксида пропилена, отличающийся тем, что процесс осуществляется в режиме пленочного течения жидкости до конверсии пероксида водорода 70-85% в первом реакторе смешения при температуре на выходе не выше 55°С, реакционная смесь из первого реактора после выделения из нее образовавшегося оксида пропилена поступает для завершения реакции во второй пленочный реактор, работающий в вытеснительном режиме при температуре на выходе из реактора не выше 70°С. The method of producing propylene oxide from hydrogen peroxide and propylene in a solvent - methanol at a temperature of 20-70 ° C on a heterogeneous titanium-silicalite catalyst in a two-stage synthesis with intermediate distillation of propylene oxide, characterized in that the process is carried out in the mode of film flow of liquid to the conversion of hydrogen peroxide 70-85% in the first mixing reactor at the outlet temperature not higher than 55 ° C, the reaction mixture from the first reactor after the separation of the formed propylene oxide from it is fed to complete the reaction tion in the second film reactor operating in the displacing mode at an outlet temperature from the reactor is not higher than 70 ° C.
