Problems solved by technology

However, when it is used alone in cigarettes, the fullness, roundness and fluency of the cigarette smoke obtained are not enough. On the other hand, the synthesis method of γ-valerolactone has relatively harsh conditions and high cost, which limits its application.

Abstract

The invention discloses a preparation method of a perfume composition, which comprises the following steps: taking levulinate as a raw material and taking secondary alcohol as a hydrogen source and a solvent, performing reaction under a catalytic action of aluminium isopropoxide to prepare gamma-valerolactone, and uniformly mixing prepared gamma-valerolactone, dihydroactinidiolide, menthyl acetate, coumarin, a compound for enhancement and a carrier to prepare the perfume composition. The raw material adopted by the preparation method is cheap; the preparation cost of the perfume composition is effectively lowered; and a preparation technology is mild in condition and easy to operate.

Description

[0001] Technical field: [0002] The invention relates to the field of fragrances, in particular to a method for preparing a fragrance composition. [0003] Background technique: [0004] As an important part of fine organic chemical industry, synthetic spices are widely used in food, cosmetics, textiles, medicine, rubber, plastics, feed, coatings, etc. There are many ways to develop synthetic fragrances. You can use cheap and easy-to-obtain natural fragrances or petroleum raw materials and intermediates to synthesize them, transform natural fragrances with complex structures that are difficult to synthesize, use new synthetic methods, and improve traditional processes. At present, there are more than 5,000 kinds of synthetic fragrances in the world, and there are more than 400 kinds of commonly used products. [0005] Among the many fragrances, ester fragrances are a very important class of fragrance essences, and ester fragrances are the most widely used and the most used ca...
