At present, among the dozens of carbamate insecticides that form commodities in various countries in the world, 1-naphthyl N-methylcarbamate is a relatively large-scale and widely-used product. The insecticide synthesis method reported in the literature more, of which methyl isocyanate synthesis method or methyl carbamoyl chloride esterification method
