ABSTRACT

We determined apparent molar volumes V/ from densities measured with a vibrating-tube densimeter at 278.15 6 (T/K) 6 368.15 and apparent molar heat capacities Cp,/ with a twin fixed-cell, differential, temperature-scanning calorimeter at 278.15 6 (T/ K) 6 363.15 for aqueous solutions of N-acetyl-D-glucosamine at m from (0.01 to 1.0) mol Ae kg 1 and at p = 0.35 MPa. We also determined V/ at 278.15 6 (T/K) 6 368.15 and Cp,/ at 278.15 6 (T/K) 6 393.15 for aqueous solutions of N-methylacetamide at m from (0.015 to 1.0) mol Ae kg 1 and at p = 0.35 MPa. Empirical functions of m and T for each compound were fitted to our results, which are then compared to those for N,N-dimethylacetamide. Estimated values of DrVm(m,T) and DrCp,m(m,T) for formation of aqueous N-acetyl-D-glucosamine from aqueous D-glucose and aqueous acetamide are calculated and discussed.
