Abstract

In the manufacture of borneol by treating pinene or camphene with an acid and hydrolyzing the resulting ester, the acid employed is of the type COOH-R-CO-R1, in which R and R1 represent aromatic nuclei, their homologues and substitution products, e.g. o-benzoylbenzoic acid, o-naphthoylbenzoic acid, 2 : 3-dichlorobenzoylbenzoic acid, 3 : 4-dichlorobenzoylbenzoic acid, 2 : 4-dichlorobenzoylbenzoic acid, tetrachlorobenzoylbenzoic acid, naphthoyltetrachlorobenzoic acid, and their bromine, iodine, nitro, methyl, hydroxyl and alkoxyl derivatives, as well as mixtures thereof. The esters obtained are readily hydrolyzed with aqueous caustic soda. Examples are given of the use of o-benzoylbenzoic acid and naphthoylbenzoic acid for the preparation of borneol from turpentine.
