Abstract
Hexaquonickel (II) bis-p-toluenesulfonate [Ni(OTs)2·6H2O] was prepared from the reaction of p-toluenesulfonic acid (PTS) and nickel hydroxide [Ni(OH)2]. Energy disperse spectroscopy, thermal-analysis instrument, infrared spectrometer, and X-ray diffractometer were used to characterize the product of Ni(OTs)2·6H2O purified by recrystallization. The influence of equivalence ratio of reactants [NPTS/NNi(OH)2], reaction temperature and reaction time on the yield of products was investigated. The results show that when the value of NPTS/NNi(OH)2 is 1.1, reaction temperature is 353 K, and reaction time is 3 h, the yield of the product is 90.86%.
