摘要: <正>以纯化的碱木质素和季铵盐型3-氨-2-羟丙基三甲基氯化铵(CHPTMAC)为原料,通过醚化反应合成木质素阳离子表面活性剂。通过对产品表面张力、氮含量和溶解性能的分析,研究了阳离子醚化剂用量、碱与阳离子醚化剂的摩尔比、反应温度和反应时间等对产品性能的影响。结果表明:合成阳离子表面活性剂的适宜条件为CHPTMAC质量摩尔浓度为4mol/kg,碱与阳离子醚化剂的摩尔比为1.3,反应温度50℃,反应时间4h;在此条件下合成的产品的表面张力为42.9mN/m,氮含量为2.53%;在不同pH时阳离子表面活性剂均具有较好的溶解性能。

Abstract: The biomass structure of Bambusa wenchouensis population was studied in this paper. The regression models of each biomass component based on DBH and the diameter of culm base were constructed. The result showed that culm biomass of B. wenchouensis accounted for 73.1%, much higher than that of Phyllostachys edulis. DBH, diameter of culmbase and the different components of B. wenchouensis were highly corretated each other. The model of culm fresh weight (W1) and total fresh weight (W4) based on DBH (D) were W1=0. 370 3 D2.0922 and W4=0. 512 2 D2.0391 respectively. By using these models, the different biomass components of B. wenchouensis could be estimated in practice.
