麦秆100℃下甲醇和乙醇醇解产物的组成分析
Compositional Analysis of the Liquid Products from Methanolysis and Ethanolysis of Wheat Stalk at 100 ℃
摘要
Abstract
[Objective]The compositional analysis of the liquid products from methanolysis and ethanolysis of wheat stalk at 100 ℃ was studied and the depolymerization of three components in wheat stalk was preliminary explored. [ Method ] Methanolysis and ethanolysis of wheat stalk extracted with solvents and the liquid products were analyzed by GC MS. [ Result] The results showed that the species and relative contents of the liquid products from methanolysis and ethanolysis of wheat stalk at 100 t were different. Methanolysis of wheat stalk favored the formation of aromatic aldehydes and ketone derivatives,aromatic alcohol derivatives and long-chain acid amides. Ethanolysis of wheat stalk favored the formation of phenol derivatives,aliphatic ketones, saccharides, benzene derivatives and long-chain alkane. [ Conclusion] The depolymerization of lignin, hemicellulose and cellulose in wheat stalk were different. Methanolysis and ethanolysis of wheat stalk were primarily the cleavage of lignin,but the major components were different. The extent of methanolysis of hemicelluloses in wheat stalk was obviously lower than the methanolysis of wheat stalk.关键词
