At present, the main industrial route is that alpha-methyl styrene and isoamylene react to generate pentamethyl indane under the condition that phosphoric acid is used as a catalyst, then the pentamethyl indane and propylene oxide carry out Friedel-crafts alkylation reaction to obtain hexamethyl indane alcohol, and the hexamethyl indane alcohol reacts with methylal to obtain galaxolide and methanol products, wherein the reaction mechanism is as follows:
in the actual industrial production of galaxolide, 1 molecule of hexamethylindanol (GLA) and 1 molecule of methylal react under the catalysis of an aluminum trichloride/chlorobenzene solvent to generate 1 molecule of galaxolide and 2 molecules of methanol, the aluminum trichloride is strongly hydrolyzed in water to release hydrogen chloride gas to form a hydrochloric acid solution, and the epoxypropane can undergo a ring-opening reaction in hydrochloric acid to form 1-chloro-2-propanol and 2-chloro-1-propanol (which are collectively called chloropropanol), wherein the reaction mechanism is as follows:
however, the boiling point (128-; on the other hand, the purity of the recovered chlorobenzene is low, so that the chlorobenzene is influenced to be used as a solvent again; methanol as a byproduct of methylal can be similar to chlorobenzene and chloropropanol solution and dissolve mutually, azeotropy is formed in the rectification heating process, a large amount of chlorobenzene and chloropropanol are taken out, and the difficulty in recovering and removing impurities from the rectified chlorobenzene is increased.
