Abstract
The densities and viscosities ofn-alkyl chlorides from pentyl chloride to hexadecyl chloride were determined at temperatures between 15 - 80 oe at 5 oe intervals. The densities increase linearly with temperature and chainlength and their correlation coefficients were better than 0.9999. At constant temperature, the molar volume was a linear function of the number of methylene unit, n, in the chain for the homologous series. A four constants equation correlating the molar volume with the number of methylene units and temperature of the n-alkyl chlorides was formulated excellent agreements between the calculated and measured values of molar volume were obtained. This formula accurately predicted the molar volume and hence the density for all the n-alkyl chlorides at any temperature within the range. The intrinsic volumes of the n-alkyl chlorides were determined by extrapolation of the plot of fluidity against molar volume to zero fluidity. Plots of the logarithm of viscosity versus reciprocal absolute temperature were almost linear. The energies of activation for viscous flow for the n-alkyl chlorides were calculated and found to increase with increase in chainlength.
