제목 Transesterification of Propylene Carbonate with Methanol Using Ionic Liquid Catalyst under Microwave Irradiation
초록 Microwaves gained considerable interest for driving chemical reactions during the past few years and found successful in the selective preparation of chemicals of interest. Along with high heat efficiency, microwave irradiation can accelerate the reaction rate and decrease the run time resulting in fewer by-products than by conventional heating. In this work we were successful in preparing DMC and propylene glycol from propylene carbonate and methanol using environmentally friendly ionic liquids (IL) as catalysts. Synthesis of DMC was performed under microwave irradiation in a Pyrex glass reactor. Several types of ionic liquids were screened as a catalyst for the transesterification of propylene carbonate with methanol under microwave irradiation. The effect of microwave power on the reaction was also studied. Comparative study for the microwave reaction with conventional method and effect of other type of ionic liquids were performed. Quaternary ammonium salt catalyst showed good catalytic activity than Imidazolium or pyridinium salts, towards the synthesis of DMC under microwave irradiation.
