Abstract
Description
[0001] Field:
[0002] The invention belongs to a method for synthesizing methyl carbamate. Background technique:
[0003] Methyl Carbomate (MC for short), also known as urethane, is an intermediate in organic synthesis, mainly used in the manufacture of herbicides, pesticides and plastic processing, and can also be used in the synthesis of sleeping pills, sedatives, and nux. Alkali, resorcinol antidotes, injections, cosolvents and coloring agents in the printing and dyeing industry can also be used as biochemical reagents for biochemical research. At the same time, methyl carbamate is the reaction raw material for the synthesis of dimethyl carbonate.
[0004] Early methyl carbamate was mainly produced by the reaction of amines and phosgene or chloroformate, which not only seriously polluted the environment but also had high production costs. In recent years, foreign countries have successively developed a new process for preparing methyl carbamate from the reaction of carbo...
