Abstract

The density of liquid and supercritical methanol has been determined experimentally from 25 to 350°C and from 500 to 8000 bar. An externally heated autoclave was used with a Monel metal liner which retarded decomposition at high temperature. Eight isotherms with 194 experimental points were obtained. The mean relative uncertainty of the specific volume is 0.4%. An equation of State in the form of a Single extended Tait equation was prepared for the entire temperature and pressure range. It has nine constants determined by a general least squares method. The mean deviation from the experimental points is 0.17%. The new data together with previous low pressure results from other authors were used to calculate functions such as compressibility, thermal expansion, entropy, enthalpy, compressibility factor and fugacity coefficients to 250°C.
