ABSTRACT:
In a process for preparing terpene esters by reaction of camphene and a low molecular weight carboxylic acid over an acid ion exchanger as catalyst, the reactants are passed from below through the acid ion exchanger located in a column-shaped reactor at such a velocity that the ion exchanger is suspended to uniformly fill the reactor, i.e. gives a pseudofluid suspended bed. In the case of the preparation of isobornyl acetate, a high specific catalyst productivity, a high selectivity of the reaction with formation of small amounts of other esters, a high degree of conversion of the reaction component used in substoichiometric amount and a high total catalyst productivity are achieved.
