C-alkylation of hydroquinone or monoethers thereof

Year	Description
1991	Invention patented by Claude Doussain, Michel Gubelmann, and Philippe-Jean Tirel on January 17th, 1991. Abstract: The alkyl hydroquinones, e.g., methyl hydroquinone (a useful intermediate in the preparation of the monomer methyl hydroquinone diacetate, itself used for the synthesis of thermotropic polymers), are prepared by reacting (C-alkylating) hydroquinone or a monoether thereof with a lower alkanal, in the vapor phase, with a catalytically effective amount of at least one solid metal oxide.
