| titleOfInvention | Method for preparing methyl lactate |
| abstract | The present invention relates to a process for the preparation of methyl lactate comprising subjecting an aqueous liquid comprising lactic acid, methanol and at least 5% by weight of a dissolved chloride salt selected from magnesium chloride, calcium chloride and zinc chloride to reaction conditions, Providing an extraction agent to the reaction mixture before and / or after the formation of and / or after formation of the tartrate, and - providing the reaction mixture to a liquid-liquid separation step, wherein the methyl lactate and the extractant Comprising separating the organic phase from the aqueous phase comprising the dissolved chloride salt. The extractant preferably comprises one or more compounds selected from C5 + ketones and C3-C10 ethers, especially C5-C8 ketones, more particularly methyl isobutyl ketone. It has been found that the process according to the invention makes it possible to prepare methyllactate efficiently and in high yield. |
