Abstract

Peroxide pulp from wheat straw by cooking had been received by cooking with reactionary mixture «H2О2-H2О-AсОН-АсООН-catalyst». The bleaching was produced by hydrogen peroxide at pH 10,5 and at concentration of fibrous suspension 10% in one stage in accordance to accepted technology for this process. Dependence of the whiteness and chemical loss from the hydrogen peroxide concentration (range 0,5–1,5%), temperature (40–50 °C) and bleaching duration (30–90 min) had approximated by regression equation of second order. It was found the easy bleaching of the peroxide straw cellulose. Optimal  bleaching conditions was found by nonlinear programming method: temperature 40 °C; concentration H2O2 1%; duration 63 min. Bleaching results to optimal condition: cellulose whiteness 89% (correspond to State Standard for hard wood sulfate cellulose), chemical loss 5,7%.
