Abstract

The process of the parent Specification is modified in that the concentration of sulphuric acid in the reaction medium is less than 0.05 per cent by weight. The reaction is preferably carried out in a medium which contains less than one per cent by weight of water, and at a temperature between 50 DEG and 90 DEG C. In examples: (1) a solution of isopropylbenzene hydroperoxide in isopropylbenzene was decomposed to phenol and acetone with a solution of sulphuric acid in acetone, the concentration of sulphuric acid in the reaction mixture being 0.04 per cent by weight; (2) as in (1) the concentration of sulphuric acid being 0.022 per cent by weight; (3) meta-di-isopropylbenzene dihydroperoxide was dissolved in acetone, added to a solution of sulphuric acid in acetone and the mixture refluxed to give resorcinol, the concentration of sulphuric acid being about 0.008 per cent by weight.
