Process for producing borneol by adopting alpha-pinene

Abstract

The invention relates to borneol production process, in particular to a process for producing borneol by adopting alpha-pinene. The process comprises the following steps: (1) esterification; (2) washing; (3) light oil distilling; (4) saponification; (5) cooling; (6) centrifugal crushing; (7) coarse crystallization; (8) fine crystallization; (9) drying. According to the process, a green catalysis method is adopted to produce the borneol, the borneol production cycle is short, the production danger coefficient is small, the pollution level is low, and the quality of the product is high.

Description

technical field

[0001] The invention relates to a borneol production process, in particular to a process for producing borneol with α-pinene. Background technique

[0002] Borneol, also known as sliced ​​brain, orange slice, dipterocarp, plum blossom borneol, jiebuluoxiang, plum blossom brain, borneol, plum ice, etc., is the crystallization obtained by extracting the resin and volatile oil processed products of dipterocarp plant Dipterocarpa , is almost pure D-borneol. It can also be synthesized by chemical methods. It can be used for blindness due to closed syndrome, red eyes, swelling and pain, sore throat and mouth sores, swelling and pain of sores, non-constriction after ulceration, etc. Ice flakes are divided into natural ice flakes and machine-made ice flakes. Machine-made ice flakes are processed products synthesized by chemical methods. It is translucent flake crystal, with a diameter of 5-15 mm and a thickness of about 2-3 mm. White, with cracks like ice on the ...
