Excess enthalpy H-E and massic heat capacity c(p) of (water plus methanol) at temperatures between 323 K and 513 K and pressures up to 10 MPa
A flow calorimetric system for measurements of the massic heat capacity c(p) and the excess enthalpy III is described. The apparatus consists of three c(p)-calorimeters and an adiabatic mixing calorimeter. Excess molar enthalpies H-m(E) and massic heat. capacities c(pM) of (water + methanol) were measured from 323 K to 513 K at pressures from 2 MPa to 10 MPa. Special attention was directed to the critical region of methanol (T-C = 513 K, p(C) = 8.1 MPa). (c) 2005 Elsevier Ltd. All rights reserved.
