| Abstract: | The activities of inorganic acids and bases on catalyzing synthesis of dimethyl carbonate by reacting methanol with glycol carbonate under atmospheric pressure were investigated. The result showed that bases performed more effectively than acids, which was related to the structures of substrates. The initial work of studying analogous catalytic activities of ammonium halides and inorganic halide salts on the reaction was finished and a mechanism was also suggested. |
