20150203507 | METHOD FOR PREPARING DIALKYLOXYDIANHYROHEXITOL BY ETHERIFICATION OF DIANHYDROHEXITOL USING A LIGHT ALCOHOL, IN THE PRESENCE OF AN ACIDIC CATALYST - A method for preparing a dialkyloxydianhyrohexitol (dimethylisosorbide) composition by etherification of dianhydrohexitol (isosorbide). The aim is to achieve a “clean” method that avoids the use of a methylation agent such as dimethyl sulfate or methyl chloride, which generates stoechiometric quantities of salts, or expensive dialkyl-carbonates, wherein only one of the two methyl groups participates in the preparation of mixed isosorbide ethers. The 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. A device for carrying out the method wherein the device includes a vaporization oven and a reaction oven is also described. | 07-23-2015 |
