Butyl carbamate is one of important organic compounds, can be used as the intermediate of organic synthesis to compound a series of compounds, such as aliphatic carbamate compound and phosphoric dipeptide, or to compound dibutyl carbonate to further synthesize diphenyl carbonate, and also can be used as cement anti-shrinking agent, textile finishing agent and crease-resistance agent. Polyacrylate modified from butyl carbamate has excellent transparence and acid rain corrosion resistance, and can be used for automotive coating.
