| Abstract: | The catalysts and reaction conditions have been studied for esterinterenange between propenyl carbonate and methanol to produce dimethyl carbonate (DMC).The results indicate that inorganic bases are suitable catalysts for the esterinterchange.Some strong bases, such as sodium hydroxide, sodium methoxide, and sodium carbonate, show high catalytic activities.The optimal reaction conditions for this process are as follows:temperature, 333 353 K; reaction time, 1h; catalyst content, 1.0～2.5%;the ratio or ester to methanol, 1/5. |
