Abstract
In an effort to develop a method for the bleaching of chemical pulps, the chlorine-ethanolamine, chlorite and peracetic acid holocellulose-preparation methods were compared with respect to yield, degradation and degree of oxidation of the wood carbohydrates. It was found that the peracetic acid method gave superior holocellulose-preparations with higher D. P., large recovery of major polysaccharides and medium size of carboxyl contents.
A preliminary study was made on bleaching the kraft pulp by using peracetic acid solution. This method results in a high yield of pulp with considerable good brightness. Further study is needed for better evaluation of the process and pulp made.
