Abstract
The hydrotropic pulping of crushed straw of Miscanthus sacchariflorus Andersson to produce pulp was studied herein. A concentrated sodium benzoate solution was used as the reagent. Established regularities of the pulping temperature and time effects on delignification quality attributes such as pulp yield and residual lignin content in the pulp. The generalized arithmetic-mean optimization parameter enabled hydrotropic pulping optimum conditions to be identified to obtain hard pulp fit. Experimentally displayed the possibility of using cellulose for the manufacture of special paper grades.
