| titleOfInvention | Heterogeneous azeotropic distillation method |
| abstract | A heterogeneous azeotropic distillation method, which requires only one distillation column, is provided. The distillation column includes a first distillation section and a second distillation section. The first distillation section is on top of the second section. In the disclosed heterogeneous azeotropic distillation method, a mixture which includes methyl methacrylate, methanol, and water is transported into the distillation column. The mixture is distilled at a temperature between 65 DEG C and 106 DEG C. A liquid stream in the end of the first section is drawn out and cooled down to form a water-rich phase and an organic-rich phase. Then, the organic-rich phase is transported back to the end of the first distillation section. In the heterogeneous azeotropic distillation method, only one distillation column is needed to obtain a high-purity methyl methacrylate. Hence the cost of the equipments and the floor space of plant site are both reduced. |
