| titleOfInvention | Method for preparing dimethyl carbonate by taking immobilized lipase as catalyst |
| abstract | The invention discloses a method for preparing dimethyl carbonate by taking immobilized lipase as a catalyst. The method comprises the following steps of immobilizing lipase by taking one or two of polyvinyl alcohol, carboxymethyl cellulose sodium and hydroxypropyl methyl cellulose as a matrix for supporting lipase; then, sequentially adding reactants, namely methanol and ethylene carbonate or methanol and propylene carbonate into a reaction device; adding the immobilized lipase into the reactants; finally, stirring for a transesterification reaction to obtain a product, namely dimethyl carbonate. According to the method disclosed by the invention, by adopting the immobilized lipase as a catalyst to catalyze the transesterification reaction between methanol and ethylene carbonate or methanol and propylene carbonate to obtain dimethyl carbonate, the preparation method realizes high conversion rate, high selectivity and high universality; moreover, the technology is simple, the reaction conditions are mild, the cost is lowered, the method is environment-friendly, the immobilized lipase can be recycled, and the application prospect is broad. |
