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△dissH=-4.7813+118.99b-105.86b1/2,△dissH=-5.8833士131.3643b-113.8384b1/2,△dissH=-5.8833+131.3643bb-113.8384b1/2和△dissH =-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△miss Hmean=—10-1.88T2+ 100.88T- 10T3.06二项式关系.%The enthalpies of dissolution of DINA (N-nitro-dihydroxyethylamie dinitrate) in DMS()(dimethyl sulfox-ide) 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:△diss H=4.781 3+11 899b-10 586b1/2, △HdissH = - 5.883 3+131.364 3b- 113.838 4b1/2 and △dissH= - 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 topolynomial equations. And the average values of enthalpies of dissolution in DMSO for DINA vs. Temperatures can be described as △dissHmean = - 10-1.89T2+100.88 T- 103.06.
