Abstract

The invention discloses a myrcene production system, comprising an alpha-pinene fractionator, a beta-pinene fractionator, a preheater, a pyrolytic device, a cooler, a vacuum buffer tank, a vacuum receiving tank, a vacuum gas storage tank and a vacuum pump; a feed port of the beta-pinene fractionator is connected with a beta-pinene mother liquid outlet of the alpha-pinene fractionator, a feed port of the preheater is connected with a beta-pinene discharge port of the beta-pinene fractionator, a discharge port of the preheater is connected with a feed port of the pyrolytic device through a first pipeline, a discharge port of the pyrolytic device is connected with a feed port of the cooler through a second pipeline, and the first pipeline and the second pipeline are jointly covered with an insulation layer. The multistage fractionators used herein cooperate with reflux action of a reflow pipe by means of multistage spraying, providing greatly improved fractionating effect, improving the purity of beta-pinene obtained by isolating and therefore ensuring the purity of finally isolated myrcene.

Description

technical field [0001] The invention relates to a production device in the field of fine chemical industry, in particular to a production system of myrcene. Background technique [0002] Myrcene is also known as myrcene, 7-methyl-3-methylene-1,6-octadiene, etc. Its molecular formula is: C10H16, its molecular weight is 136.23, and there are two conjugated double bonds and one single A double bond is an important chemical raw material and intermediate in the fragrance industry, such as the synthesis of mint, citral, citronellol, geraniol, nerol and linalool. 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 and other fields. There are two ways to o...
