NTO在DMSO和NMP中的溶解性能(英文)

Dissolution Properties of NTO in Dimethyl Sulfoxide and N-methyl-2-pyrrolidone

用RD496-2000型微热量仪测定了常压和298.15K下3-硝基-1,2,4-三唑-5-酮(NTO)在二甲基亚砜(DMSO)和N-甲基吡咯烷酮(NMP)中的溶解焓。从NTO在DMSO和NMP中的溶解过程实验数据得到了溶解焓(ΔdissH)、相对偏摩尔焓(ΔdissHpartial)和表观摩尔焓(ΔdissHapparent)与溶液浓度的经验式及NTO在DMSO中溶解过程的动力学方程dα/dt=10-3.78(1-α)0.98和在NMP中溶解过程的动力学方程dα/dt=10-3.74(1-α)1.06。

The enthalpies of dissolution for 3-nitro-1,2,4-triazol-5-one（NTO） in dimethyl sulfoxide（DMSO） and N-methyl-2-pyrrolidone（NMP） were measured using a microcalorimeter,type RD496-2000 at 298.15K under atmospheric pressure.Empirical formulae of the enthalpy of dissolution （△dissH）,relative partial molar enthalpy （△dissHpartial）,and relative apparent molar enthalpy （△dissHapparent） vs.the concentration of solution,and the dissolution processes kinetic equations dα/dt=10-3.78（1-α）0.98 for the dis solution of NTO in DMSO and dα/dt=10-3.74（1-α）1.06 for the dissolution of NTO in NMP were obtained from the experimental data of the dissolution processes of NTO in DMSO and NMP.
