The effect of hydroxypropyl-β-cyclodextrin (HPβCD) on the improvement of chlorpropham (CIPC) as a potato sprout inhibitor was investigated. The formation of complex was confirmed by FT-IR spectra, thermoanalysis, (1)H NMR and ROESY. The stoichiometry and stability constant were determined by Job's plot and phase solubility studies, respectively. The inclusion complex CIPC·HPβCD has exhibited different properties from CIPC. The obtained inclusion complex was found to significantly improve the water solubility, thermal stability and dissolution rate of CIPC. In addition, the complex displayed a better effect on sprout inhibition.
研究了羟丙基-β-环糊精（HPβCD）对氯苯胺灵（CIPC）作为马铃薯抑芽剂的增效作用。通过傅里叶变换红外光谱（FT-IR）、热分析、（1）H NMR 和 ROESY 确认了配合物的形成。通过 Job 作图和相溶解度研究分别确定了配合物的化学计量比和稳定常数。所得包合物 CIPC·HPβCD 表现出与 CIPC 不同的性质。发现所得包合物显著提高了 CIPC 的水溶性、热稳定性和溶解速率。此外，该配合物对抑芽效果更好。
