Embodiment 1

[0011] The longifolene fragrance includes 65% longifolene and 17.6% longifolene by weight. The production of 1 ton of longifolene requires the following steps: use 2.9 tons of longifolene with a content of 24%, caryophyllene Heavy turpentine with a content of 6.3% enters a vacuum distillation tower for high-vacuum distillation, and when the pressure of the vacuum vacuum distillation is 1Kpa, the fraction whose tower top temperature of the distillation tower is 110°C to 118°C is taken, and finally obtained 1 ton of longifolene fragrance products with a longifolene content of 65% and a caryophyllene content of 17.6%. The longifolene fragrance is used in spices and has its own unique woody aroma. It has similarities with the longifolene flavor type with a longifolene content of more than 80%, and has its own characteristics. It has been widely used.

Embodiment 2

[0013] The longifolene fragrance includes 69% longifolene and 18% caryophyllene by weight, and the following steps are required to produce 1 ton of the longifolene fragrance: use 3 tons of longifolene with a content of 24%, caryophyllene The heavy turpentine with a content of 6.3% enters the vacuum distillation tower for high vacuum distillation, and the fraction with a top temperature of 110-118°C is taken under the pressure of the vacuum vacuum distillation at 1Kpa, and finally 1 A longifolene fragrance product with a longifolene content of 69% and a caryophyllene content of 18%. The invention is applied to spices and has its own unique woody aroma, which has similarities with the longifolene-flavor type with a longifolene content of more than 80%, and has its own characteristics, and has been widely used.

Embodiment 3

[0015] The longifolene fragrance includes 72% longifolene and 18.7% caryophyllene by weight. The production of 1 ton of longifolene needs to be carried out as follows: use 3.1 tons of longifolene with a content of 24% and caryophyllene. 6.3% of the heavy turpentine enters the vacuum distillation tower for high vacuum distillation, and the distillation tower top temperature is 110°C to 118°C when the pressure of the vacuum vacuum distillation is 1Kpa, and finally 1 The longifolene content is 72% per ton, and the longifolene content is 18.7%. The invention is applied to spices and has its own unique woody aroma, which has similarities with the longifolene-flavor type with a longifolene content of more than 80%, and has its own characteristics, and has been widely used.

Abstract

The invention discloses a longifolene perfume material and a preparation method thereof. The longifolene perfume material comprises longifolene with content being 65-75 percent and caryophyllene with content being more than 17 percent. The preparation method of the longifolene perfume material comprises the following steps of: putting heavy turpentine in a distillation tower, conducting high-vacuum depressurized distillation, and intercepting fraction with temperature being 110-118DEG C at the top of the distillation tower at high-vacuum depressurized distillation pressure being 1Kpa. Compared with the prior art, the problem of high production cost of the existing longifolene perfume material and the preparation method thereof can be solved.

Description

technical field [0001] The invention relates to the technical field of chemical turpentine deep processing, in particular to a longifolene with a spice content of about 60% longifolene and a preparation method thereof. Background technique [0002] Heavy turpentine Guangxi is one of the main turpentine producing areas in my country and Southeast Asia, with an annual output of more than 10,000 tons and rich resources. Heavy turpentine is a by-product of turpentine, accounting for about 20% to 30% of turpentine production. In recent years, many scholars at home and abroad have carried out research on isolating longifolene from heavy turpentine and then synthesizing isolongifolene and its series of products, and achieved many scientific research results. However, the longifolene extracted at present is actually a mixture of longifolene, β-caryophyllene and other sesquiterpenes, which are called longifolene spices, and the content of longifolene monomers is generally 60% to 78%...
