General Description

1,2,3,4,5,6,7,8-octahydro-5,5-dimethylnaphthalene-2-carbaldehyde, also known as OTNE, is a synthetic chemical compound commonly used in the fragrance and flavor industry. It is a colorless to pale yellow liquid with a strong, sweet, musky odor. OTNE is often used as a fragrance ingredient in perfumes, colognes, and other scented products. It is known for its long-lasting and strong odor, making it a popular choice for creating a variety of scents. Additionally, OTNE is also used as a flavoring agent in the food and beverage industry, providing a sweet and musky taste to certain products. Despite its widespread use, concerns have been raised about the potential health risks associated with OTNE, including its possible effects on the endocrine system and its potential to cause skin irritation and allergic reactions in some individuals.

Method for preparation of cyclic myrac aldehydes from myrac aldehyde catalyzed by zinc-containing ionic liquid

The invention provides a novel method for catalyzing cyclization reaction of myrac aldehyde for conversion to cyclic myrac aldehydes by using a Lewis acidic ionic liquid as a catalyst. According to the method, by using a zinc-containing ionic liquid as a catalyst and under the mild condition, 4-(4-methyl-3-pentenyl)-3-cyclohexenal(p-myrac aldehyde) and 3-(4-methyl-3-pentenyl)-3-cyclohexenal (m-myrac aldehyde) undergo selective cyclization to prepare cyclic myrac aldehydes (1,2,3,4,5,6,7,8-octahydro-,8,8-dimethyl-2-naphthaldehyde and 1,2,3,4,5,6,7,8-octahydro-5,5-dimethyl-2-naphthaldehyde). Incomparison with a traditional cyclic myrac aldehydes production method, the invention has the following distinctive characteristics: the use of a volatile organic solvent is avoided in the reaction; the reaction condition is mild; the target product has high selectivity, and the reaction is rapid; after the reaction, the ionic liquid catalyst and the product are automatically layered and are convenient to separate; the ionic liquid catalyst is recyclable; generation of a waste acid solution by traditional catalysis is avoided; and the method is environmentally friendly.
