Abstract
Hydroxy compounds of the formul <FORM:0653351/IV (b)/1> are manufactured by reacting 4-vinylcyclohexene dioxide with water, preferably in the presence of an inorganic acid (e.g. nitric, sulphuric or perchloric acid), as catalyst. The reaction may be carried out at 20-80 DEG C., e.g. for 20-30 minutes at 75-80 DEG C. The nature of the products depends on the pH of the reaction medium, one or both of the dihydroxy compounds being formed at about pH 4.0, the tetrahydroxy compound at about pH 2.5, and mixtures of di- and tetra-hydroxy compounds at intermediate values. Detailed examples are given. The products are useful as intermediates for further reactions, e.g. the tetrahydroxy compound forms a tetra-acetate by treatment with acetic anhydride. Specifications 648,456 and 651,797 are referred to.
