Qualitative and Quantitative Analysis of the Product and By-Products from Transesterification between Phenol and Dimethyl Carbonate

Figure 5

The effects of temperature (a), pressure (b), and ligands of organic tin catalyst (c) on the product and by-products from transesterification. Reaction conditions: (a) phenol: 10 g; n(phenol) = n(DMC); catalyst (dibutyltin oxide): 0.20 g; reaction time: 12 h; and reaction pressure: 0.3 MPa. (b) Phenol: 10 g; n(phenol) = n(DMC); catalyst (dibutyltin oxide): 0.20 g; reaction time: 12 h; and reaction temperature: 180°C. (c) Phenol: 10 g; n(phenol) = n(DMC); catalyst: 0.20 g; reaction time: 12 h; reaction temperature: 240°C; and reaction pressure: 0.5 MPa.
