The present invention in general relates to a method for the deacylation and/or dealkylation (both O-dealkylation as well as C-dealkylation) of compounds, more specifically of aromatic compounds. The method is characterized by contacting the compound with an acid-containing aqueous reaction mixture using high temperature and high pressure conditions. The invention also provides a method for preparing a compound suitable for further deacylation using the method of the invention.

Disclosed herein is a process for chemically synthesizing of hydroquinone derivatives, especially for hydroquinone derivatives with heptadecatrienyl side chain, which is synthesized via a Wittig reaction of 2-(10-oxononyl)-1,4-diacetoxyl benzene and (3E, 5Z)-3,5-heptadien-1-triphenylphosphonium iodide and then deacetylation. In addition, the product is solid powder.
