查询词典 distillation

The source and formation mechanism of methyl carbamate in liquor covered the followings:①methyl carbamate formed by spontaneous chemical reaction of carbamide and methanol in fermented and undistilled alcoholic beverage;②in alcohol produced by grains as raw materials, cyanide precursor of grains formed into cyanate during fermentation and distillation, which further developed into methyl carbamate in alcohol.
