摘要：The partial molar volume of Paracetamol (4-acetamidophenol) in water,0.1 M HCl solution and 0.9% NaCl solution at 298.15K,303.15 K,308.15 K and 310.15 K have been evaluated with the help of vibrating tube densitimeter Anton Paar (DMA 48). The effect of 0.1 M HCl solution whose pH is comparable with the pH of stomach and 0.9% NaCl solution is comparable with the isotonic solution of human fluid were checked. The results were fitted by the regression to equation that describe the plot (V,T,m). At infinite dilution,partial molar volumes were obtained over the range of temperature by extrapolating these plots to m = 0 mol/kg..
