摘　　要：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 enthalpies of dissolution of DINA（N-nitro-dihydroxyethylamie dinitrate） in DMSO（dimethyl sulfoxide） were measured by means of a calvet microcalorimeter at 302.15,306.15,310.15 and 313.15 K,respectively.Empirical formulae for the calculation of the enthalpies of dissolution at four different temperatures were：ΔdissH=4.781 3＋11 899b-10 586b1/2,ΔHdissH=-5.883 3＋131.364 3b-113.838 4b1/2 and ΔdissH=-6.638 1＋136.327 2b-115.302 7b1/2 correspondingly.All of the coefficients of A,B and C at different temperatures vary according to polynomial equations.And the average values of enthalpies of dissolution in DMSO for DINA vs.temperatures can be described as ΔdissHmean=-10-1.89T2＋100.88T-103.06.
