Abstract
253,542. Darrasse, L., Darrasse, E.., and Dupont, L. June 12, 1925, [Convention date]. Bornyl esters.-In a process as described in Specification 164,357, for the production of bornyl esters by heating together turpentine, oxalic acid, and a solvent, simple hydrocarbons such as benzene, toluene, and other hydrocarbons of this series or mixtures thereof are used instead of chlorinated hydrocarbons. As the reaction is slower the relative proportion of solvent used is increased. In an example dry oxalic acid, turpentine, and a mixture of toluene and benzene are heated together, the quantity of solvent being two or three times the quantity of turpentine. Specification 14408/08. [Class 2, Acids and salts, Organic &c.], also is referred to.
