摘要
本文用相平衡法研究了NiCl_2—(CH_2)_6N_4·HCl—H_2O 三元体系在30℃的溶解度,测定了各液相的折光率。结果表明生成了复合物2NiCl_2·(CH_2)_6N_4·HCl·9H_2O.文中介绍了该三元体系在13°O 时平衡固相的热致变色性能,通过TG—DTA 研究初步探讨了热致变色机理。
The solubility of the ternary system of NiCl_2-(CH_2)_6N_4·HCl-H_2O at30℃ has been investigated by the phase-equilibrium method,the refractiveindexes of the liquid phases have also been determined separately.Theresults show that the double salt which has the composition of 2NiCl_2-(CH_2)_6N_4·HCl·9H_2O is formed in the cited ternary system.The thermochr-omic chracteristic of the equilibrium solid phase at 13℃ have been studiedand its thermochromic mechanisms are inquired preliminarily.
