| titleOfInvention | Solvent composition for separating m-methyl-ethylbenzene from p-methyl-ethylbenzene by extractive distillation and extractive distillation method |
| abstract | The invention discloses a solvent composition for separating m-methyl-ethylbenzene from p-methyl-ethylbenzene by extractive distillation and an extractive distillation method. The solvent composition comprises: 90-99 parts of phenylacetonitrile, and 1-10 parts of acetate. The acetate is sodium acetate or potassium acetate. The method is to separate m-methyl-ethylbenzene from p-methyl-ethylbenzene by performing extractive distillation of a mixture of m-methyl-ethylbenzene and p-methyl-ethylbenzene by using the solvent composition in an extractive distillation tower. With the solvent composition and the extractive distillation method of the invention, the separation efficiency of m-methyl-ethylbenzene and p-methyl-ethylbenzene is improved; the chemical thermal stability is good; the solvent composition is easy to recover; and the operation is low in energy consumption. |
