Abstract

Effect of four reaction factors including reaction time, concentration of NaOH, propylene oxide, and composition (methanol : water, v/v) of reaction medium was determined on hydroxypropyl content (%) and viscosity of hydroxypropyl guar gum using orthogonal design of experiment. Among all synthesized hydroxypropyl guar gum derivatives highest viscosity, and hydroxypropyl content was determined 5708.0 cPs and 0.487% respectively. Taguchi L9 (3⁴) design of experiment suggested 3 h and 0.1 mol as optimized reaction duration and concentration of etherifying reagent for higher hydroxypropyl content as well as viscosity. Optimized amount of NaOH was determined 0.03 and 0.02 mol for hydroxypropyl content and viscosity respectively. While the optimized composition of reaction medium (methanol : water, v/v) was determined 7 : 1 and 9 : 1 for hydroxypropyl content and viscosity respectively. Reaction time, and concentration of propylene oxide were determined as most impacting factor for hydroxypropyl content and viscosity of hydroxypropyl content respectively. Optimized products determined to exhibit 0.83% and 5902 cPs of hydroxypropyl content and viscosity respectively.

关于优化反应条件以合成具有更高粘度和羟丙基含量的羟丙基瓜尔胶的比较研究：统计方法

摘要采用正交实验设计法测定了反应时间、NaOH 浓度、环氧丙烷浓度和反应介质成分（甲醇：水，v/v）等四个反应因素对羟丙基瓜尔胶羟丙基含量（%）和粘度的影响。在所有合成的羟丙基瓜尔胶衍生物中，粘度和羟丙基含量最高的分别为 5708.0 cPs 和 0.487%。Taguchi L9 (34) 实验设计建议将 3 小时和 0.1 摩尔作为优化反应时间和醚化试剂浓度，以获得更高的羟丙基含量和粘度。针对羟丙基含量和粘度，NaOH 的最佳用量分别为 0.03 和 0.02 摩尔。羟丙基含量和粘度的最佳反应介质成分（甲醇：水，v/v）分别为 7 : 1 和 9 : 1。反应时间和环氧丙烷浓度分别被确定为对羟丙基含量和羟丙基粘度影响最大的因素。优化后的产品羟丙基含量和粘度分别为 0.83% 和 5902 cPs。
