摘要
用步冷曲线法和DSC法研究了NaOAc—Na_4P_2O_7—H_2O体系中NaOAc·3H_2O—Na_4P_2O_7·10H_2O截面,绘制出本截面的多温图,同时发现NaOAc·3H_2O饱和溶液对Na_4P_2O_7·10H_2O有很强的脱水作用。
The cooling curves method and DSC method were used to study solidliquid equilibrium of the section NaOAc·3H_2O-Na_4P_2O_7·10H_2O in ternary system NaOAc-Na_4P_2O_7-H_2O. It was found that there are two ternary invariant temperatures: 40.2℃ and 58℃ Experiment results show the saturated sodium acetate trihydrate solutions have a very strong dehydrating influence on the sodium pyrophasphate decahydrate.
