Isolation, Study and Application of Organosolv Lignins (Review)

Abstract

The analysis of the literature on the methods of soluble organosolv lignins isolation, their physicalchemical study and on the method of their processing to porous aerogels and liquid hydrocarbons was carried out. A review of the literature allowed us to choice of the most important areas of research. For isolation from wood the soluble lignins free from sulfur the methods of catalytic peroxide delignification at mild conditions (temperature 100 C, atmospheric pressure) and methods of lignin extraction by supercritical organic solvents were used.
