Abstract: Process for the preparation of camphene by the rearrangement of .alpha.-pinene In the preparation of camphene by the rearrangement of .alpha.- pinene, the reaction time can be shortened by carrying out the rearrangement under reflux. The heat of reaction produced is eliminated by evaporative cooling. The composition of the reaction mixture can be controlled by monitoring the temperature towards the end of the reaction.

Abstract: Terpene esters are prepd. by reacting C10H16 terpenes with a lower carboxylic acid, in molar ratio of terpene:acid of 0.2-2:1, at 25-60 deg.C, on an acid ion-exchanger as catalyst. The reactants are passed upwards through a tubular reactor contg. the catalyst, at a rate such that the ion-exchanger is held in uniform suspension in the reactor.
