| titleOfInvention | The method for preparing methyl lactate |
| abstract | The present invention relates to a kind of method for preparing methyl lactate, it the described method comprises the following steps：By containing lactic acid, methanol and at least liquid, aqueous introducing reaction condition of the hydrochloride of 5wt% dissolving, it is derived from methyl lactate, the hydrochloride is selected from magnesium chloride, calcium chloride and zinc chloride, wherein extractant is provided to reactant mixture before, during and/or after methyl lactate is formed, reactant mixture is set to undergo Liquid liquid Separation step, wherein by the aqueous phase separation of the organic phase containing methyl lactate and extractant and the hydrochloride containing dissolving.Extractant preferably includes one or more compounds selected from C5+ ketone and C3 C10 ethers, particularly C5 C8 ketone, more particularly methyl iso-butyl ketone (MIBK).It has been found that the method for the present invention can be effectively and to prepare methyl lactate in high yield. |
