Abstract RU 2631508 C1

FIELD: chemistry.

SUBSTANCE: method consists in oxidizing lignin-containing wood raw materials with oxygen in an alkaline medium at elevated temperature and pressure in the presence of an organic additive. Herewith sodium salt of copper tetrasulfophthalocyanine is used as an additive in the amount of 0.1-0.4 g/l of the reaction mass.

EFFECT: increasing the yield of the target product, shortening the duration of the process.
