| titleOfInvention | Procedure to produce a diphenylsulfone compound |
| abstract | Process for the preparation of a compound of formula (I) ** Formula ** (in which R1 and R2 are each independently halogen, alkyl having 1 to 8 carbons or alkenyl having 2 to 8 carbons; m and n are , each independently, 0 or an integer from 1 to 4; and R3 is alkyl having 1 to 8 carbons, alkenyl having 2 to 8 carbons, cycloalkyl having 3 to 8 carbons or optionally substituted aralkyl), characterized in that , in a process for producing a compound of formula (I) by reacting a compound of formula (II) ** Formula ** (in which R1, R2, myn are as defined above) with an excess of a compound of formula (III) R3-X (III) (in which R3 is as defined above and X is halogen) in a solvent in the presence of a base and the reaction obtained is purified, a process is provided for a part without react of the compound of formula (III) be removed from the solution n produced by the reaction of the compounds of formulas (II) and (III), in which the process for removing the compound of formula (III) is a process for removing the compound of formula (III) together with the reaction solvent from the reaction solution by distillation. |
