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ΔG0→w、ΔS0→w和ΔH0→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。
Partition coefficients of quaternary ammonium salt of thioureido imidazoline between water and oil were measured,from which thermodynamic parameters of ΔG0→ w,ΔS0→ w and ΔH 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.
