Paragraph 0066-0075, (2017/02/09)
The invention discloses a method of preparing a floralozone intermediate. Under the action of an aqueous sulfuric acid solution and a quaternary ammonium salt as a phase transfer catalyst, by controlling the reaction temperature, hydrogen chloride gas is continuously fed into a reaction system containing ethylbenzene and paraformaldehyde so as to perform chloromethylation of the ethylbenzene, and ethylbenzyl chloride with a purity higher than 95% and a yield being 85-94% is finally prepared. By adoption the ethylbenzyl chloride as the intermediate, floralozone can be prepared by condensing the intermediate and isobutyraldehyde.

A process for producing an aromatic aldehyde compound has steps of converting alkyl-substituted or non-substituted benzene into a compound of formula I by halomethylation, and allowing the compound of formula I and alkyl aldehyde to react in presence of phase transfer catalyst at a reaction temperature under alkaline condition to obtain the aromatic aldehyde compound.
