Abstract

THE OBJECTIVES

The work was carried out for extraction of natural anthrasesamones from roots of Sesamum Indicum using different organic solvents and utilization of extracts as catalyst in pulping with sodium hydroxide for a by-product of sugar industry (Sudanese bagasse).

RESULTS

Sesamum Indicum roots when extracted with ethanol, it gave the highest extracts yield % (0.964), followed by ethyl acetate, chloroform, dichloromethane and petroleum ether extracts. The chemical pulping of Bagasse was done by using of sodium hydroxide, sodium hydroxide with anthraquinone, and sodium hydroxide with extract instead of anthraquinone keeping constant conditions at temperature 160 °C and applied sodium oxide 10.9% and time was 120 min, gave promising screened yield between 49.84 and 53.68%, bleachable kappa number between 15.57 and 8.26 for sodium hydroxide only and cooking with sodium hydroxide with anthraquinone. Cooking with sodium hydroxide of bagasse with anthrasesamones gave good pulping yields and kappa number.

摘要

目的

开展从芝麻根中使用不同有机溶剂提取天然蒽芝麻素，并将提取物用作氢氧化钠制浆的催化剂，用于制糖工业的副产品（苏丹甘蔗渣）。

结果

用乙醇提取芝麻根时，提取物产率最高（0.964%），其次是乙酸乙酯、氯仿、二氯甲烷和石油醚提取物。甘蔗渣的化学制浆是在温度160°C、氧化钠用量10.9%、时间120分钟的恒定条件下，分别使用氢氧化钠、氢氧化钠与蒽醌、氢氧化钠与提取物（代替蒽醌）进行的，仅使用氢氧化钠以及氢氧化钠与蒽醌蒸煮时，筛选得率在49.84%至53.68%之间，可漂卡伯值在15.57至8.26之间。用氢氧化钠与蒽芝麻素蒸煮甘蔗渣可获得良好的制浆得率和卡伯值。
