Apparatus for continuously cracking beta-pinene to produce laurene

Abstract

The invention discloses an apparatus for continuously cracking beta-pinene to produce laurene. The apparatus comprises a charging pump, a vaporizer, a cracker, a heat exchanger, a cooler and a product collector which are sequentially connected; the charging port of the charging pump is connected with a raw material tank, the discharging port of the charging pump is connected with the upper end of the vaporizer through a guide tube, a nonvolatile matter collector is connected below the vaporizer, a gas mixing chamber is arranged above the vaporizer, the heat conduction material inlet and the heat conduction material outlet of the vaporizer are respectively connected with an eduction tube in front of and behind the eduction tube valve of the cracker, the gas mixing chamber is connected with the heat conduction material inlet of the heat exchanger, the heat conduction material outlet of the heat exchanger is connected with the charging port of the cracker, the charging port of the heat exchanger is connected with the discharging port of the cracker through a valve, and the heat exchanger is connected with the product collector. The apparatus has the advantages of low energy consumption, high reaction efficiency, uniform heating, low cost, high laurene output and realization of continuous cracking production of laurene.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a device for continuously cracking β-pinene to produce myrcene. Background technique [0002] Myrcene is also known as myrcene, 7-methyl-3-methylene-1,6-octadiene, etc., and its molecular formula is: C 10 h 16 , Molecular weight: 136.23, there are two conjugated double bonds and a single double bond in the molecule, it is an important chemical raw material and intermediate in the fragrance industry, such as synthetic mint, citral, citronellol, geraniol, orange Flower alcohol and linalool etc. Myrcene is a colorless or light yellow oily liquid at room temperature, soluble in organic solvents such as ethanol, ether, and chloroform, and miscible with most spice intermediates. Myrcene has a strong fruity, floral, green, woody and lemony aroma. Because of its unique aroma quality, it is widely used in medicine, tobacco, food ingredients, perfume, cosmetics, soap, detergent a...

AI Technical Summary

Problems solved by technology

In recent years, researchers have done more research on myrcene production methods, but less research on its production equipment

In the device for cracking β-pinene to produce myrcene, there are still problems such as high energy consumption, high production cost, uneven heating, low output, and long reaction time.
