Abstract
New express technique of the analysis paper compositions is offered. Based on one of lignin colour reactions - reaction of nitrosition by nitrous acid. The basic laws of the given reaction are investigated and optimum conditions of treatment of lignocellulosic materials by nitrous acid in vivo for realization of the analysis of various papers are developed. Is shown, that the offered technique does not concede on the accuracy to an earlier offered technique of the analysis with use barbituric acids.
