Results indicated that the yield of pulp and the pentosan content in the pulp increased with increment of the ratio of sodium sulfite to the total sodium (all calculated as sodium oxide), but the potassium permanganate value in the pulp changed in a "N" shape. The material, pretreated and unpretreated by hot water, requires at least a total sodium of 16% and 17.5% (calculated as sodium hydroxide) respectly. when the ratios of sodium sulfite to the total sodium are controlled at 82-87%, the yield of pulp exceeds 50%, and the brightness and pentosan contents of pulp are higher and the potassium permanganate value in the pulp are lower than otherwise.

Ethyl alcohol pulping is a nsw pulping method without or less pullution to environment.The advantages of this process are higher yield,the solvent could be used repeatedly and easy to recover it. The eolour of pulp treating by this method is light and easy for bleaching. Hemicellulose of bagasse and its change during the process of ethanol-water pulping had been studied by means of gas-liquid chromatography.It has been found that the bagasse hemicellulose is essentially composed of arabinose and xylose,with the weight ratio of 1∶15.Arabinose dissolved continnously during pulping.Xy- lose also dissolved as arabinose at the first stage of extraction.but in later the dissolviog curve became steady and the content of xylose in pulp did not change any.About 50—60 per cent of arabinose and 76—80 per cent of xylose were retained in un-bleaching pulp. Only a lttle amount of cellulose lost at 170℃ for 8 hours.Cellulose was not found to be seriously degraded in other extracting cond- itions,therefore,high yield of pulp was obtained. The GC separation efficiency for acetylated aldononitride and alditol acetate of components of noncellulosic carbohydrate in pulp had also been compared in this paper.The results showed that the acetylated aldon-onitride is better than alditol acetate,and the former method was suitable for in analyzing the component of polysaccharide in raw material or pulp.

乙醇法制浆是一种少污染的新制浆方法。具有得率高,未漂浆颜色浅,易于漂白,化学药品回收简单,乙醇可循环使用,对空气和水源污染少等优点。本试验用气—液相色谱技术对制浆过程的甘蔗渣半纤维素进行研究,发现蔗渣的半纤维素主要由阿拉伯糖和木糖组成,其重量比为1∶15。制浆过程阿拉伯糖不断溶出,木糖在萃取初期象阿拉伯糖一样溶出,随后渐趋稳定,含量基本保持不变。未漂浆中尚保留50—60%阿拉伯糖和76—80%的木糖。除经170℃8小时恒温萃取后发现少量的纤维素降解外,其余各萃取木素过程未发现纤维素的强烈降解,粗浆得率可达60—66%。本文还比较了糖腈醋酸酯法和糖醇醋酸酯法对纸浆中非纤维素碳水化合物成分的分离效果。实验证明前者效果比后者好。适用于研究造纸原料和纸浆中糖类成分的分析,具有推广意义。
