Abstract
It is investigated a way of receiving pulp from wheat straw by hydrogen peroxide in the environment of acetic acid. This way provides a fibrous semi-finished product high-performance of quality: yield of pulp from 55 to 88% and content of residual lignin from 2,3 to 18,3%. Temperature effect and durations of process of oxidizing delignification on indicators of quality of pulp is investigated. It is calculated mathematical dependences of delignification of wheat straw
