Title:
PREPARATION OF CAMPHENE BY REARRANGEMENT OF ALPHA-PINENE
Document Type and Number:
Japanese Patent JPH05221883
Kind Code:
A
Abstract:
PURPOSE: To prepare camphene with a small amt. of a catalyst in a short reaction time while safely removing generated heat energy.
CONSTITUTION: When camphene is prepd. by rearranging α-pinene under the action of heat in the presence of a titanium dioxide hydrate catalyst, the rearrangement is carried out at 155-165°C under the reflux of the α-pinene and the generated heat of reaction is removed by vaporization cooling.
