Synthesis of Long Chain Aliphatic Carbonic Esters by Catalytic Alcoholysis of Urea
Abstract:
Some metal oxides, organic and inorganic salts were studied as catalyst for synthesis of aliphatic carbonic ester by alcoholysis of urea. It is found that ZnO has higher catalytic activity in the catalysts tested with diisoamyl carbonate yield 58.3%~76.3%, when reaction is carried out at 160~200℃ for 8 h, the molar ratio of isoamyl alcohol to urea and mass fraction of catalyst are 3.3 and 0.85% respectively.
