Sustainable production of active pharmaceutical ingredients from lignin-based benzoic acid derivatives via “demand orientation”

Abstract

Research related to lignin utilization has drawn extensive attention from academia to industry. However, the wide distribution and low economic value of depolymerization products make the valorization of lignin to...

Protocol for the preparation and application of CeO2-CuO catalysts in the decarboxylative oxidation reaction of benzoic acids to phenols

“…Benzoic acids are abundant and stable chemicals. Recent studies show that benzoic acids can also be produced from the oxidative depolymerization of lignin 10 , 11 , 12 , 13 , 14 or degradation of polystyrene. 15 , 16 Therefore, direct synthesis of phenols from benzoic acids by heterogeneous catalysis will be a potential method for commercial phenols production from renewable resources.…”

Recent advances in catalytic conversion of lignin to value-added chemicals using ionic liquids and deep eutectic solvents: a critical review

“…It has an aromatic ring and phenolic hydroxyl group that are identical to those of phenol. 23 An overview of the manufacture of APIs utilizing lignin was published by Dong et al 24 with a focus on the use of lignin-based benzoic acid derivatives as raw materials. They aim to offer a greener, more environmentally conscious method of offering a sustainable route for the manufacturing of APIs.…”

Visible-light-driven photocatalytic carboxylation to aromatic carboxylic acids with CO2

“…(Hetero)aromatic carboxylic acids and their derivatives, which are considered an important class of compounds, are widely utilized in the food industry, medicine and veterinary fields, and synthesis of biologically active molecules, dyes, polymers, agricultural chemicals, and corrosion inhibitors. 1–4 Their industrial synthesis mainly involves the oxidation of alkyl-, alkenyl-, and alkynylaromatic compounds. 5–7 Because of the extensive application of aryl carboxylic acids and their derivatives, more efficient alternative methods for synthesizing them are constantly developed.…”
