Production process of N-(N-cyclohexylamide-N', N'-dmethyl amidine)-N-methyl ethyl carbamate

Abstract

The invention relates to a production process of N-(N-cyclohexylamide-N', N'-dmethyl amidine)-N-methyl ethyl carbamate. The process consists of: taking cyanamide, ethyl chloroformate, dimethyl sulfate, dimethylamine, cyclohexyl isocyanate and the like are adopted as the main raw materials, and carrying out condensation, synthesis, alkaline hydrolysis, synthesis and other reactions so as to obtain N-(N-cyclohexylamide-N', N'-dmethyl amidine)-N-methyl ethyl carbamate. With yield up to 85%, the production process has the advantages of short technological process, simple preparation, production safety and good prospects, and is suitable for large-scale plant production.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis, in particular to a production process of N-(N-cyclohexylamide-N',N'-dimethylamidine)-N-methylurethane. Background technique [0002] Triazine herbicides mainly use D1 protein as the target of photosynthetic system Ⅱ (PSⅡ) to inhibit the photosynthesis of plants and play a big role in agriculture. Among them, N-(N-cyclohexylamide-N', N'-dimethylamidine)-N-methylcarbamate is an intermediate of triazine herbicides, which plays a very important role in making triazine herbicides, but the existing N-( The production process of N-cyclohexylamide-N', N'-dimethylamidine)-N-methyl urethane is relatively complex, cumbersome to operate, high in production cost, and low in efficiency. Contents of the invention [0003] The present invention provides a kind of N-(N-cyclohexyl amide-N', N'-dimethylamidine)-N-methyl urethane production technology for solving above-mentioned deficiency, makes its t...
