Abstract: Lignin is a promising substitute for phenol in phenol-formaldehyde (PF) resin formulation. It is readily available and low toxic as a by-product from the pulp and paper industry. However, lignin is a three-dimensional amorphous biopolymer with high molecular weight and low reactivity. To date, many methods such as thermochemical conversion, pyrolysis, liquefaction, supercritical water treatment, oxidation, reduction, hydrolysis, etc. have been made to degrade macromolecular lignin into lower molecular weight fractions containing useful chemicals, which are important intermediates in the chemical industry for a diversity of products. The present work discusses the potential for an increased use of lignin as a renewable raw material. A brief overview about present state of lignin oxidative degradation is given and phenolic compounds from lignin are presented, and its large-scale production is prospected.
