Lactococcus nitrile France

Method lactonitrile
lactic acid powder is the acetaldehyde and hydrogen cyanide cold milk continuously fed to the reactor to generate a nitrile (or directly with the milk as raw material nitrile), with a pump into the milk nitrile hydrolysis reactor, into sulfuric acid and water to make milk nitrilase to give the crude acid. And then give it away crude lactic acid esterification reactor, adding ethanol esterification, distillation, concentration, lactic acid decomposition was fine. American Sterling Chemical Company and Japan Zinc lactate Chemical companies are adopting this synthesis of lactic acid.
