造纸黑液木质素及其综合利用

Lignin And It's Comprehensive Utilization

木质素是结构复杂的数量上仅次于纤维素的芳香族天然高分子物质,是人们提取和利用纤维素时的副产品,本文主要对国内近几年来有关木质素特别是造纸黑液木质素的综合治理和应用技术研究成果进行了综述,内容包括木质素化学结构及其在农林业、石油工业、混凝土工业、高分子材料和合成低分子化学品等领域的综合利用。

Lignin is a natual polymeric material that has complex chemical constitute and is second only to cellulose on the amount. It is by - product which cellulose was extracted and utilized. The research achievement on the comprehensive disposal and the application technique of lignin,especially papermaking back liquor was, mainly summarized in recent years. This paper covered chemical constitute and comprehensive utilization of lignin, especially pulping back liquor, in agriculture, forestry, petroleum industry, concrete industry ,polymer material and synthesis of little molecule chemical.
