    Abstract: A process for treating an aqueous solution (A) derived from a method of producing a compound of formula (I), wherein R1 and R2 are identical or different and are chosen from among hydrogen and C1-C5 alkyl, wherein R1 and R2 together form a methylene group, and wherein R3, R4, R5 and R6, which are independently identical or different, are chosen from among: a hydrogen atom, a hydroxy group (—OH), an alkoxy group (—OR), an alcohol group (—ROH), an aldehyde group (—CHO), a ketone group (—C(═O)R), an acid group (—COOH), a nitrile group (—CN), a C1-C6 alkyl chain, linear or branched, saturated or unsaturated, potentially comprising one or a plurality of substitutes in a terminal or lateral position or one or more functions in said alkyl chain, R being a C1-C5 alkyl, wherein the aqueous solution (A) comprises at least one sulfate salt SO42−(S) rendered soluble and at least one aromatic organic compound (O) formed during the method for producing the compound (I), and wherein the process comprises at least one step (i) of recovering a solid sulfate salt (S) in an at least partially anhydride form separately from the aqueous solution (A).
