The transesterification of di-Me carbonate with phenol to Me Ph carbonate (MPC) was investigated on novel catalysts such as titanium diisopropoxide bis(Et acetoacetate) and titanium dibutoxide bis(Et acetoacetate) in a closed batch reactor at 185-206°C under high pressure. The produced methanol could be removed efficiently by reactive distillation in order to overcome the equilibrium The prepared catalysts have higher resistance to water than titanium alkoxides. Phenol conversion as high as 86.4% with an MPC selectivity of 99.4% was achieved under optimal reaction conditions within 9 h. Most of the catalytic activity was retained after repeated use for ten times. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Formula: C13H10O3).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Formula: C13H10O3
