用微热量仪研究了302.15、306.15、310.15和313.15温度下N-硝基-二乙醇胺二硝酸酯(DINA)在二甲基亚砜中的溶解性能,得到不同温度下的溶解焓与物质浓度之间的关系式分别为ΔdissH=-4.7813+118.99b-105.86b1/2,ΔdissH=-5.8833±131.3643b-113.8384b1/2,ΔdissH=-5.8833+131.3643bb-113.8384b1/2和ΔdissH=-6.6381-136.3272b-115.3027b1/2。进一步研究发现关系式中的A、B、C系数值随温度的变化规律服从ΔdissHmean=-10-1.89T2+100.88T-103.06二项式关系。
The solubility of N-nitro-diethanolamine dinitrate (DINA) in dimethylsulfoxide at 302.15, 306.15, 310.15 and 313.15 was investigated by microcalorimetry, and the enthalpies of enthalpy and concentration at different temperatures were obtained ΔdissH = -5.8833 + 131.3643bb-113.8384b1 / 2 and ΔdissH = -6.6381 -12, respectively, and the relationship between ΔdissH = -4.7813 + 118.99b-105.86b1 / 2, ΔdissH = -5.8833 ± 131.3643b-113.8384b1 / 2, 136.3272b-115.3027b1 / 2. Further study found that the relationship between the A, B, C coefficient values with the temperature changes obey ΔdissHmean = -10-1.89T2 +100.88T-103.06 binomial relationship.
