Technical Document

Brief Overview
Beta pinene is a colorless liquid, soluble in alcohol, but not water. It has a woody-green pine-like smell. It occurs naturally in rosemary, parsley, dill, basil and rose, There are two structural isomers found in nature: a-pinene and β-pinene.
Manufacturing Process
Beta pinene is produced by putting alpha-pinene in a reaction kettle, adding a catalyst, raising the temperature to 120-180 degrees Celsius, and carrying out an isomerization reaction for 0.5-1 hour with a palladium catalyst using diatomite as a carrier. The invention discloses a method for isomerizing alpha-pinene into beta-pinene using a palladium catalyst and diatomite as the carrier, so that the method is simple in process and easy to operate, a catalyst method is simple, and high-purity beta-pinene is obtained; thus, the method provides a new idea for beta-pinene preparation.
