氰化物

Automatic screening algorithm of abnormal data for linear regression calculation, improved algorithm for kinetic analysis and temperature calibration algorithm for enzyme analysis were successfully used in the portable spectrometer. 4. More than ten kinds of chemical reagent kits for rapid determination of environment monitoring and food safety coupled with the portable spectrometer were studied, such as Cr, Pb, Cd, NO2-,,NO3-, formaldehyde, sodium formaldehyde sulfoxylate, COD, NH4+, PO43+, CN-, F, Cl2, etc.

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.

白酒中氨基甲酸甲酯的来源和形成机理主要有：①在已发酵的和未蒸馏的酒精饮料中尿素和甲醇自发的化学反应生成氨基甲酸甲酯；②以谷物为原料生产的酒精中，氨基甲酸甲酯形成的途径来源于谷物的氰化物前体在发酵和蒸馏时反应形成的氰酸盐，氰酸盐在酒精中转化为氨基甲酸甲酯。
