Title (EN) METHOD FOR THE DEACYLATION AND/OR DEALKYLATION OF COMPOUNDS
(FR) PROCÉDÉ DE DÉSACYLATION ET/OU DE DÉSALKYLATION DE COMPOSÉS
Abstract:
(EN) 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.
(FR) La présente invention concerne d'une manière générale un procédé de désacylation et/ou de désalkylation (O-désalkylation et C-désalkylation) de composés, plus précisément de composés aromatiques. Le procédé est caractérisé par la mise en contact du composé avec un mélange réactionnel aqueux contenant un acide dans des conditions de haute température et de haute pression. L'invention concerne également un procédé de préparation d'un composé se prêtant à une désacylation ultérieure à l'aide du procédé de l'invention.
