酮-醇体系超额焓的研究(Ⅰ)——丙酮(1)-正丙醇(2)体系超额焓的测定和关联

EXCESS ENTHALPY FOR THE KETONE-ALCOHOL SYSTEM ( Ⅰ) ACETONE(1)+n-PROPANOL(2) SYSTEM

利用低温型CALVET微量量热计测定了常压下25,30和35℃正丙醇-丙醇二元系超额焓数据,并用六参数Redlich-Kister方程和NRTL模型进行了关联。

Excess enthalpy data of acetone(1)+n—propanol(2) system are measured by a low temperature Calvet microcalorimeter at the ambient pressure and the temperatures of 25, 30 and 35℃, and the data measured are correlated with six-parameter R-K equation and NRTL equation.
