Embodiment 1

[0021] The invention provides a kind of borneol camphor camphor natural borneol separation process, comprising the following steps:

[0022] S1, select raw material, distinguish each part of camphor borneol, and choose the leaves of camphor borneol as raw material;

[0023] Raw material selects borneol camphor leaves, selects 270g of borneol camphor leaves, removes the petiole of borneol camphor leaves, and then cleans them with clear water; the natural borneol content in the borneol camphor leaves is the most, and the dried borneol camphor branches and leaves are divided, They are branch bark, branch xylem, terminal branches and leaves respectively, and then carry out rough extraction, and the extracted natural borneol mass fractions are respectively: 50.2%, 24.3%, 47.6% and 71.5%, and it is known that natural borneol in borneol camphor leaves The content is the most, choosing the leaves of borneol camphor tree as raw material can make it easier to increase natural borneol, a...

Abstract

The invention relates to the technical field of natural borneol manufacturing, in particular to a cinnamomum camphora natural borneol separation process which comprises the following steps: S1, selecting raw materials, and distinguishing various parts of cinnamomum camphora, wherein leaves of cinnamomum camphora are selected as the raw materials; S2, putting the cinnamomum camphora leaves into a crusher for crushing, and putting the crushed cinnamomum camphora leaves into water added with gasoline for soaking; S3, pouring the soaked borneol camphor tree leaf powder into an extraction tank for boiling, installing a guide pipe at the top of the extraction tank, and connecting the other end of the guide pipe with a crystallization chamber; and S4, installing a plurality of cotton ropes at the top end of the inner wall of the crystallization chamber, installing a condenser outside the crystallization chamber, and inputting argon into the crystallization chamber. By arranging the cotton rope and increasing the pressure intensity in the crystallization chamber, natural borneol can be crystallized on the surface of the cotton rope more quickly, crystallization of the natural borneol is accelerated, the forming time of the natural borneol is shortened, and the time for collecting crystals of the natural borneol is also shortened.

Description

technical field [0001] The invention relates to the technical field of natural borneol production, in particular to a separation process of borneol camphor natural borneol. Background technique [0002] Borneo camphor tree is a precious and rare medicinal material, a high-grade spice, and an important chemical raw material. Borneocampus is also a raw material for making natural borneol. Natural borneol is the name of a traditional Chinese medicine. It is extracted and processed from fresh branches and leaves of Lauraceae plants. Made, natural borneol is white crystalline powder or flaky crystal, fragrant, pungent, cool, volatile, thick smoke when ignited, and the flame is yellow. [0003] Nowadays, steam distillation is mostly used in the production of natural borneol. The operation is simple, the investment is low, and the purity of natural borneol is relatively high. However, the production takes a long time and the production efficiency is low, which needs to be improved....
