scientist Lev Efraimovich Akim. He graduated with honors from the Leningrad Molotov Institute of Technology (1953), a student of Professor N. P. Perekalsky, and post-graduate studies at the Department of Wood and Pulp Chemistry of the Forestry Academy, where he studied under Viktor Mikhailovich Nikitin.

new method of bleaching cellulose-oxygen (chlorine-free) bleaching. During the oxygen-alkaline treatment of cellulose, three main reactions take place: the oxidation of lignin, the oxidative destruction of cellulose, and the removal (under certain conditions) of hemicelluloses, low-molecular fractions of cellulose, resinous and other substances from cellulose.
