Пример. К 193 г смеси, содержащей 146 г а-пропиленхлоргидрина и 48 г |: -пропилеихлоргидрина , добавл ют 20 /э-ную водную суспензию, содержащую 186 г гидрата окиси никел . Продукт реакции подвергают перегонке. В дистилл те наход т 28 г пропионового альдегида и 5,5 г окиси пропилена , в остатке-134 г. неизменного а-пропиленхлоргидрина, не реагирующего с гидратом окиси никел , но при взаимодействии сExample. To 193 g of a mixture containing 146 g of a-propylene chlorohydrin and 48 g of |: -propylene-hydrochloride, add 20 / e aqueous suspension, containing 186 g of nickel hydroxide. The reaction product is subjected to distillation. In the distillate, 28 g of propionaldehyde and 5.5 g of propylene oxide are found, the remainder is 134 g of unchanged a-propylene chlorohydrin, which does not react with nickel hydroxide, but interacting with
гидратом окиси кальци образующего окись пропилена.calcium oxide hydrate forming propylene oxide.
Предмет изобретени Subject invention
Способ выделени а-пропиленхлоргидрина из смеси его с S-npoпилеихлоргидрином , о т л и чающийс тем, что, с ,елью упрощени процесса, на смесь а-и З-пропиленхлоргидринов воздействуют кип щей водной суспензией гидроокиси никел с отгонкой продуктов реакции.The method of separating a-propylene chlorohydrin from its mixture with S-propylene-hydrochloride, is made in that, with a simplification of the process, the mixture of a-and 3-propylene chlorohydrins is affected by boiling aqueous suspension of nickel hydroxide and stripping the reaction products.
