Abstract

The present invention relates to a method for preparing a dialkyloxydianhyrohexitol (dimethylisosorbide) composition by etherification of dianhydrohexitol (isosorbide). The aim of the invention is to achieve a 'clean' method that avoids the use of a methylation agent such as dimethyl sulfate or methyl chloride which generate stoechiometric quantities of salts or expensive dialkyl carbonates wherein only one of the two methyl groups participates in the preparation of mixed isosorbide ethers. Said method involves using at least one O alkylation agent and a catalyst including an acid or an acid salt preferably a catalyst having Lewis or BrØnsted acid properties. The present invention further relates to a device for carrying out the method according to at least one of the previous claims characterized in that said device includes a vaporization oven and a reaction oven.
