CARBAMATES. When heated to
decomposition it emits toxic fumes of NOx | | Synthesis | GENERAL STEPS: First, the catalyst was prepared by calcining Yb(NO3)3-6H2O in air at 350 °C for 4 hours. Subsequently, 48.0 g of n-butanol, 6.0 g of urea and 0.75 g of the above prepared catalyst were added to an autoclave. The reaction was carried out at 180°C for 6 hours under autogenous pressure (about 8.5 atm). At the end of the reaction, the yields of dibutyl carbonate (DBC) and butyl carbamate (BC) were 43.1% by weight and 12.8% by weight, respectively. | | References | [1] RSC Advances, 2015, vol. 5, # 25, p. 19534 - 19540
