With the improvement of environmental protection requirements, paper-making enterprises are imperative to eliminate pollution directly in production. This paper aims to adopt environment-friendly bleaching method, yield good quality pulp products. Op-Pa-P bleaching process of reed displacement cooking pulp is studied in this paper (O-oxygen, P-hydrogen peroxide, Pa-peracetic acid ). The experimental conditions of Op and Pa stage were optimized respectively. It included oxygen pressure, temperature, time in Op stage and charge of peracetic acid, temperature, time in Pa stage. The results show that the optimal technological conditions of Op are: 0.9Mpa, 100°C, 70min, Op stage can make brightness increase by 57.3%, viscosity decrease by 25% and KMnO4 number reduce to 2.6. Pa stage optimal conditions are Pa charge 1.5%, 70°C, 75min, brightness reached to 79.1 %ISO, KMnO4 number to 1.0, viscosity to 631mL.g-1. The brightness of P bleached pulp reached to 84.8%ISO, viscosity 601 mL.g-1, KMnO4 number 0.8.

An environment-friendly plasticizer, epoxidized corn oil was prepared by the epoxidation of corn oil with peroxyacetic acid which was generated in situ from hydrogen peroxide and glacial acetic using acidic ion exchange resin modified by zinc chloride as catalyst. The product with an epoxy oxygen content of 6.40 w% and a percent conversion to oxirane of 87.67 % was obtained under the following optimized conditions: 15 % modified ion exchange resin feed relative to the weight of corn oil, the molar ratio of 1.7 to 1 with hydrogen peroxide to double bonds, 18% acetic acid feed relative to the weight of corn oil, the reaction time of 5.5 h, the temperature of 75 °C and stirring speed of 600 rpm.
