• 要約等: Peracetic acid (PA) is an effective bleaching agent for bleaching chemical pulps to a high degree of brightness. A study was carried out on the effect of stabilizer during PA bleaching of Kraft pulp (KP) in vapor-phase under mild condition.<BR>Chelating agents such as Daiseru stabilizer, 1, 2-cyclohexane DTA, chelespar 7 G and dipicolinic acid among stabilizers employed depressed effectively the auto-degradation of PA under bleaching conditions. According to the main experimental results, PA vapor-phase bleaching of KP in the presence of above stabilizers was necessary to carried out in an air-tight apparatus under following conditions ; pulp consistency 33%, PA addition 22%, stabilizer addition-Daiseru stabilizer 0.018%, chelespar 7 G 0.47%, dipicolinic acid 0.18%, pH 4, 0, temperature 90°C time, NUKP 1 hr and LUKP 15 min.<BR>The brightness of BKP such obtained was about 90%. The yield of BKP was nearly quantitative. The amount of PA used could be decreased about 4 o per pulp by adding the small amount of stabilizer into PA solution, which was prepared by Greenspan's method, The properties of BKP were greatly unaffected by using stabilizer, as indicated for viscosity, K value and pentosan content. Tear factor and Folding end. of BKP decreased considerably by bleaching with PA in the presence of dipicolinic acid. But, the influence on the mechanical properties of the pulp by the other chelating stabilizers was little.<BR>One of the most important variables for the brightness of BKP.was an effective bleaching with hydrogen peroxide present in PA solution during vapor-phase bleaching. This fact revealed that KP prepared with hydrogen peroxide-containing PA solution give higher brightness than the pulp bleached with PA solution in the absence of hydrogen peroxide under same conditions.
