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...
