Abstract
Procedure for the preparation of sulfones derived from 2,5-dihydroxybenzene monosulfonic and 2,5-dihydroxybenzenedisulfonic acids, of general formula: ** (See formula) ** Wherein R is an aryl, alkanoaryl or arylalkan radical and B represents an unsubstituted or substituted, open chain or cyclic alkali metal, alkaline earth metal, ammonia or amine cation, consisting essentially of reacting a formula quinone: ** (See formula) ** where R1 is H, R2 can be H or -SO3.B and that when R1 is -SO3.B, R2 is H, with a sulfinic acid of formula: R-SO2H where R has the same meaning as described above.
