Abstract:
The kinetics and thermodynamics of hexadecylpyridiumchlorid in solvent sublation were studied. With the measurement of the surface forces at different temperatures and concentration,the free standard adsorption energy ΔG0adswas obtained with - 33. 17kJ / mol. The process of solvent sublation of hexadecylpyridiumchlorid is obedient to first order kinetics. The apparent rate coefficient decreases with the increase of experiment temperature but increases with the increase of the air flow rates.
Key words:  Solvent sublation,Thermodynamics,Kinetic,Hexadecylpyridiumchlorid

十六烷基氯化吡啶溶剂气浮的热力学及动力学研究
吕玉娟*,朱锡海
摘要:
研究了表面活性剂十六烷基氯化吡啶(HPC)的溶剂气浮回收动力学及热力学规律。通过测定不同温度及浓度下HPC的表面张力,得到了HPC在气-液界面的标准吸附表面自由能为-33.17kJ/mol。HPC的溶剂气浮过程符合一级动力学方程,表观速率常数k的值随气体流速升高而增加,随温度升高而降低。
