Title:
ジアンヒドロヘキシトールのジアルキルカーボネートを調製するための方法
Document Type and Number:
Japanese Patent JP2013506645
Kind Code:
A
Abstract:
A method for preparing dialkyl carbonates of dianhydrohexitol, includes the following steps: (a) preparing an initial reaction mixture containing at least one dianhydrohexitol, at least two mole equivalents of a dialkyl carbonate of formula and a transesterification catalyst; (b) heating the reaction mixture to a temperature greater than or equal to the boiling temperature of the formed alcohol, or of the azeotrope thereof, in a reaction chamber preferably provided with a rectification column including a sufficient number of theoretical distillation plates to separate the resulting alcohol from the reaction mixture. Certain dialkyl carbonates of dianhydrohexitols produced by the method and the use thereof for synthesizing synthetic polymers are also described.
