Abstract
The present invention relates to a process for producing phenol and a ketone of general formula R1COCH2R3 (I), in which R1 and R2 each independently represent an alkyl group having from 1 to 4 carbon atoms, said process comprising: in which R1 and R2 have the same meaning as in formula (I) and in which X represents a carbonyl (CO) group or a sulfonyl (SO2) group, n is 0, 1, 2, 3 or 4, R3 is one or several groups selected from a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an amino group and R4 is a hydrogen atom, an alkaline metal cation or an alkaline earth metal cation, or in the presence of N,N′,N″-trihydroxyisocyanuric acid (THICA), to produce a product comprising a hydroperoxide of general formula (IV)in which R1 and R2 have the same meaning as in formula (I), and
