米粉 (QS) 纳米晶体是通过酸水解生产的,以稳定高内部相乳液 (HIPEs). 较长的水解时间产生了较少的纳米晶体,但形成了稳定的高内部相乳液凝 (HIPE凝).
科学领域:
- 材料科学 材料科学 材料科学
- 合体和表面化学
- 生物聚合物科学 生物聚合物科学
背景情况:
- 粉纳米晶体 (SNC) 是高内部相乳液 (HIPE) 的有效稳定剂.
- 对于SNC生产而言,传统的酸性水解效率低.
- 米粉 (QS),其小颗粒大小,为SNCs提供了替代来源.
研究的目的:
- 通过不同的酸水解时间来研究QS衍生的SNCs的生产.
- 描述QS在水解过程中的结构变化.
- 评估QS-SNCs作为HIPE稳定剂的潜力,特别是形成HIPE凝.
主要方法:
- 奎诺亚粉的酸水解0-4天.
- 使用Tyndall效应和扫描电子显微镜 (SEM) 对QS纳米晶体的表征.
- 分析颗粒大小分布,水解程度,产量和相对晶度.
- 制备和评估高内部相乳液 (HIPEs) 及其凝性质.
主要成果:
- 增加水解时间 (1-4天) 降低了QS纳米晶的产量 (30.4%至10.8%),但增加了水解程度 (51.2%至87.8%).
- 通过Tyndall效应和SEM证实了QS纳米晶体,观察到粒子大小分布的变化.
- 通过水解,QS的相对晶度从22.27%增加到26.18%.
- 由QS-SNC稳定的HIPE从3-4天的水解中形成了独立的HIPE凝,这是由于密集的界面包装和高表面粘度造成的.
结论:
- 麦粉的酸性水解可以产生适合稳定HIPEs的粉纳米晶体.
- 优化的水解条件对于平衡纳米晶产量和乳液稳定至关重要.
- 米粉衍生的纳米晶体为新型高内部相乳液凝 (HIPE凝) 提供了一个有前途的途径.

Polyprotic Acids
Acid Strength and Molecular Structure
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
