A DATA-BANK FOR AZEOTROPIC DATA - STATUS AND APPLICATIONS

A computerized bank of azeotropic data is now available. Data from the literature have been tested before storage. Newly measured azeotropic and zeotropic data are also included, which were obtained for the pur pose of verifying questionable literature information and also for sys tems for which no data had been available. This data bank now contains approximately 36 000 entries (information) on azeotropic or zeotropic behavior or approximately 19 000 non-electrolyte systems involving ap proximately 1700 compounds. It can be used reliably in process synthes is computations, e.g. for design calculations of distillation columns, selection of the best solvents for azeotropic distillation and also f or further development of group contribution methods or for fitting re liable g(E)-model parameters. This compilation will increase the capab ilities of existing software tools, such as the Dortmund Data Bank and the integrated program packages (Gmehling, J., 1991. Development of t hermodynamic models with a view to the synthesis and design of separat ion processes. In: J. Gmehling (Ed.), Software Development in Chemistr y 5. Springer-Verlag, Berlin, Chapter 1.) for process design, synthesi s and simulation.
