乳酸甲酯

Methyl lactate, also known as lactic acid methyl ester, is a monobasic ester formed from lactic acid and methanol, commonly used as a solvent. Methyl lactate belongs to the lactate ester group of compounds that are considered nontoxic and highly and readily biodegradable.

生产方法
精制方法:乳酸甲酯易水解,常含有游离的乳酸、甲醇和水等杂质。游离的酸可用碱中和后洗涤除去。水分可通过与苯组成的共沸混合物进行共沸蒸馏除去。然后在减压下蒸馏精制。由于氯化钙等与乳酸甲酯形成分子化合物,故不能用作干燥剂。乳酸甲酯与水混合时,可用苯、乙醚等萃取回收。与其他液体混合时,一般用蒸馏的方法回收。 1.可作为高沸点溶剂、洗净剂、合成原料等。用作硝酸纤维素、醋酸纤维素、醋酸丁酸纤维素、醋酸丙酸纤维素以及纤维素醚的溶剂。作硝酸纤维素漆和涂料的溶剂时,可提高涂料的抗发白性和延展性。
