=============================================================================
Purpose:
Food industry: widely used as a food flavoring, added to cakes, ice cream, chocolate, candies, cookies and other foods to provide milk and vanilla aromas.
Daily chemical products: used in soap, toothpaste, perfume, face cream and other cosmetics as essence ingredients.
Pharmaceutical field: As a pharmaceutical intermediate, used for synthesizing other drugs.
Industrial applications: Can be used as electroplating varnish, rubber deodorizer, and as a flavoring agent in the tobacco industry.
Research and Analysis: Used as an analytical reagent, for testing substances such as proteins and nitrogen-containing indenes, and as a standard for organic trace ana========================================================================
There are several industrial methods for synthesizing routes, including:
Lignin route: Using lignosulfonate salts contained in the waste liquid of sulfite pulp in the paper industry as raw materials, high temperature and high pressure hydrolysis is carried out under alkaline conditions, followed by dehydration and oxidation to produce vanillin. Canada and the United States mainly use this method for production.

Guaiacol formaldehyde route (nitroso method): Guaiacol is used as the raw material to undergo condensation reaction with formaldehyde and para nitrosodimethylaniline in the presence of a catalyst, followed by extraction, distillation, and crystallization purification to obtain vanillin. The former Soviet Union and countries such as China mainly adopted this method.
one
The route of guaiacol glyoxylate: using guaiacol and glyoxylate as raw materials, vanillin is obtained through condensation, oxidation, decarboxylation and other steps. This route was developed by the French company Rhone Poulenc and has the advantages of easy availability of raw materials, fewer steps, and less pollution. It is considered a relatively suitable method at present.

In addition, vanillin can also be obtained by isomerization and oxidation of eugenol from natural vanilla extracts or plant sources such as clove oil, and such products are called "natural equivalent vanillin".
