摘要： The invention concerns a method for preparing a dianhydrohexitol diester composition, characterized in that it comprises a step which consists in esterifying a dianhydrohexitol composition with a carboxylic acid in the presence of an acid catalyst and hypophosphorous acid. Preferably, the hypophosphorous acid is introduced in an amount ranging between 0.05 and 2 wt. % of dianhydrohexitol, and in a hypophosphorous acid/acid catalyst weight ratio less than 1/1. Said method enables novel dianhydrohexitol diester compositions, for example isosorbide diesters, isomannide and/or isoidide richer in diester(s) and/or less coloured, useful in numerous industrial applications, in particular in plastic compositions, to be obtained.

摘要： The present invention relates to a method for preparing dialkyl carbonates of dianhydrohexitol, said method including 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 comprising a sufficient number of theoretical distillation plates to separate the resulting alcohol from the reaction mixture. The invention also relates to certain dialkyl carbonates of dianhydrohexitols produced by said method and to the use thereof for synthesising synthetic polymers.
