PROCESS FOR PRODUCING ARYL VINYL SULFONE SOLUTION AND USE THEREOF |
| 摘要 |
A process for producing a purified aryl vinyl sulfone solution, characterized by crystallizing an aryl vinyl sulfone from a crude organic solvent solution of the sulfone, removing the solution from the resultant mixture to obtain a wet aryl vinyl sulfone cake, and dissolving the cake in a solvent selected among C4-8 ethers, C6-10 aromatic hydrocarbons, C1-6 halogenated hydrocarbons, C3-8 ketones, C3-6 esters, and C2-6 nitriles.
