PROCESS FOR PRODUCING ARYL VINYL SULFONE SOLUTION AND USE THEREOF |
摘要 |
<p>A process for producing a purified aryl vinyl sulfone solution, characterized in that an aryl vinyl sulfone is crystallized from an organic solvent solution of a crude aryl vinyl sulfone to give a crystallization mixture, and a wet cake of the aryl vinyl sulfone obtained by the separation of the solution from the said mixture is dissolved in a solution-forming solvent selected from ethers of 4 to 8 carbon atoms, aromatic hydrocarbons of 6 to 10 carbon atoms, halogenated hydrocarbons of 1 to 6 carbon atoms, ketones of 3 to 8 carbon atoms, esters of 3 to 6 carbon atoms, and nitriles of 2 to 6 carbon atoms.</p> |
