The present disclosure relates to an improved, environmentally friendly, process for producing compounds such as hydroquinone (benzene-1,4-diol) and its derivatives. The process can be carried out at ambient temperature and pressure using a recyclable copper catalyst and recyclable intermediate materials. The process generally entails reacting an aromatic compound such as benzene with hydrogen peroxide in the present of a pure elemental copper catalyst or a copper (I) salt catalyst to form oxidation product such as benzoquinone, and reducing the compound to hydroquinone or a hydroquinone derivative.

A method for preparing 2-alkylanthracene includes the step of separating 2-alkylanthracene from a reaction product of anthracene alkylation reaction. The anthracene alkylation reaction is a reaction of anthracene and an alkylation reagent under an alkylation condition and in the presence of an alkylation reaction solvent and a catalyst. The reaction product of the anthracene alkylation reaction contains anthracene and the product of a series of alkylanthracenes containing 2-alkylanthracene.

The present invention generally relates to the production of vanillin and related compounds (such as aromatic carboxylic acids, quinones, etc.) involving the oxidative cleavage of aromatic compounds (such as lignin, lignols, cinnamic acid and its derivatives, etc.) under mild reaction conditions. More specifically, the present invention provides processes for the production of vanillin involving the oxidative cleavage of an aromatic compound, such as lignin or ferulic acid, using a peroxide based oxidant, such as hydrogen peroxide, in the presence of a suitable catalysis, such as vanadium oxide.
