Abstract:

Partition coefficients of quaternary ammonium salt of thioureido imidazoline between water and oil were measured，from which thermodynamic parameters of DG_{0® w}，DS_{0® w} and DH _{0® w} were obtained. Effects of temperature，salt concentration，oil-water ratio，inhibitor concentration and time on the mass transfer between water and oil were examined. Results showed that temperature，oil-water ratio，inhibitor concentration have a positive effect on the mass transfer between the two phases，while salt concentration has a negative effect.

摘要：

测定了硫脲基烷基咪唑啉季铵盐缓蚀剂在油水两相中的分配系数，通过分配系数和有关假设，计算出硫脲基烷基咪唑啉季铵盐缓蚀剂在分配时的DG_{0® w}、DS_{0® w}和DH _{0® w}值，并考察了温度、盐浓度、油水比例、缓蚀剂浓度和时间对缓蚀剂在两相间传质的影响。结果表明：温度、油水比例和缓蚀剂浓度对油水两相间传质起着正效应，而盐浓度对油水两相间传质起着负效应作用。
