Substitution reaction
It is one of the important reactions of most aroma chemicals, and more complex compounds can be synthesized from simple aroma chemicals through substitution reactions. The substitution reaction on the aromatic nucleus includes three types: electrophilic, nucleophilic, and free radical substitution. The most common one is electrophilic substitution, such as halogenation, nitration, sulfonation, alkylation, and acylation. aroma chemicals have important applications in the organic synthesis industry.Oxidation reaction
Any reaction that can increase oxygen or lose hydrogen in a molecule or lose electrons to elements or ions is collectively called an oxidation reaction. The oxidation reaction can convert aroma chemicals into aldehydes, ketones, carboxylic acids, quinones, epoxides, peroxides, etc., these products are important intermediates and raw materials for organic synthesis, many of which have been widely used in medicine and pesticides , Dyes, fragrances, various additives, engineering plastics and functional polymers. Condensed ring aroma chemicals are also prone to oxidation reactions due to their electron-rich structure.
