Synthetic process of galaxolide

The invention relates to a synthetic process of galaxolide. When an intermediate 1,1,2,3,3-pentamethylindane is prepared, macroporous strong-acidic styrenes cation exchanging resin prepared by the process is selected as a catalyst to react under a condition of no solvent, so that the pollution of waste gas, waste solids and waste water can be reduced, the solid catalysis is easy to separate, the industrialized production is facilitated, and the yield reaches up to 70 percent or more.

CIRCULAR ECONOMY METHODS OF PREPARING UNSATURATED COMPOUNDS

Process for the production of compounds useful in perfumery

Process for producing compounds useful in perfumery including isochromans and acylated indane hydrocarbons with an alkylene oxide or with a lower acyl halide in the presence of a hydrocarbon or hydrocarbon mixture containing C5 to C10 alkanes at a temperature of from -20° C. up to -5° C. In the case of forming isochromans, the resulting alcohol is reacted, in situ, with a lower alkanol and a formaldehyde precursor at temperatures of from 20° C. up to 80° C.
