摘要
首次利用盐酸甲胺、盐酸二甲胺、盐酸三甲胺与无水 Ｎｉ Ｃｌ２ 在室温条件下进行固相反应合成四氯合镍酸甲铵、四氯合镍酸二甲铵和四氯合镍酸三甲铵，利用近红外、红外、可见光谱以及 Ｄ Ｓ Ｃ对反应产物进行了研究，探讨了取代铵中烷基的数目对反应产物相变温度的影响，并计算了相变焓．
Methyl,dimethyl and trimethyl ammonium tetrachloronickelates were prepared by solid state reactions of methyl;dimethyl;trimethyl amine hydrochlorides with anhydrous nickel chloride at room temperature for the first time. Near IR,IR,visible spectra and DSC were used to study products. The effects of number of methyl group in substituted ammonium on phase transition temperature were investigated and enthalpy changes of phase transition were calculated .
