Chemische Eigenschaften
4,6,6,7,8,8-Hexamethyl-1,3,4,6,7,8-hexahydrocyclopenta[g]benzopyran is a viscous liquid with a musk-like odor. It is one of the most frequently used synthetic, artificial musk fragrances.The starting material for its synthesis is 1,1,2,3,3-pentamethylindane, which is prepared by cycloaddition of tert-amylene to α-methylstyrene. The pentamethylindane is hydroxyalkylated with propylene oxide in a Friedel–Crafts reaction using aluminum chloride as a catalyst (analogous to the synthesis of phenylethyl alcohol from benzene and ethylene oxide . Ring closure of the resulting 1,1,2,3,3-pentamethyl-5-(β-hydroxyisopropyl)indane is accomplished with paraformaldehyde and a lower aliphatic alcohol via the acetal or with paraformaldehyde and a carboxylic acid anhydride via the acylate.
The commercial product is diluted with solvents (e.g., diethyl phthalate, isopropyl myristate, benzyl benzoate) to make it less viscous. It is alkali-stable and does not discolor in light. Therefore, it is a popular ingredient of perfume compositions for soaps, detergents, and cosmetics and is used in large amounts.
