Production process of novel tricyclodecene esters

Abstract

The invention relates to the technical field of perfume production, in particular to a production process of novel tricyclodecene esters. The method comprises the following specific steps: 1) adding acid and removing water, 2) carrying out catalytic reaction, 3) filtering and recycling, and 4) treating the product. By adopting the supported solid catalyst, the catalyst can be recycled, and the neutralizing and washing step in the liquid acid catalyst process is reduced, so that the generation of a large amount of wastewater is reduced, and the smell of the perfume product can be greatly improved; the liquid acid in the step (1) is dewatered to remove moisture in the liquid acid, so that the activity of the catalyst is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of perfume production, in particular to a production process of novel tricyclodecenyl esters. Background technique [0002] A spice is a substance that can be smelled by the sense of smell or tasted by the sense of smell. It may be a "single body" or a "mixture". Spices can be divided into two categories: "natural spices" and "synthetic spices" according to the production method or raw materials. [0003] Natural spices refer to certain physiological organs of animals or plants (also collectively referred to as organisms) that contain aroma components, such as scent glands, sachets, flowers, leaves, branches, stems, etc. and secretions (such as gums, resins, incense, etc.) Ointments, etc.), and substances containing aroma components (such as essential oils, extracts, balsams, absolutes, etc.) that are processed and extracted from these tissues or secretions. [0004] Synthetic spices refer to those "single...

AI Technical Summary

Problems solved by technology

[0005] However, the problems existing in the processing and production process of existing synthetic spices are mainly manifested in: (1) in the production process, the catalyst generally cannot be recycled, resulting in an additional step in the liquid acid catalysis process: neutralization and washing steps, thereby producing a large amount of (2) Due to the presence of some moisture in the liquid acid, the moisture can easily destroy the activity of the catalyst, resulting in a reduction in the catalytic effect
