Water and ethanol form an azeotrope with cyclohexane for distillation at normal pressure. Finding this out takes only a few seconds with the Infotherm® database. Using the convenient search engine to explore the data trove further, one quickly learns that glycol can be used as one possible alternative to cyclohexane. However, there are also about 20 other substances as possible substitutes. Depending on which substitute is chosen for whatever reason - cost, availability, hazards, etc - properties such as the heat capacity, viscosity and density of the mixture as well as its phase equilibrium will change, of course. How will these change? Infotherm® will provide precise information on these points as well.
The database provides more than 500 tables with measurements for this simple distillation problem. The facts and data in the tables are drawn from scientific publications from more than 100 authors who have studied the problem since the beginning of the 19th century and published their findings in professional media.
The thermophysical material database provides measurements, tables and charts on the properties of material mixtures and pure substances from approx. 21,000 substances with a high-performance search engine for convenient access as required.
Is your problem an entirely different one? Do you have a technical question on another substance? This is also not a problem! With values for approximately 100 thermodynamic and physical properties, which can be combined with 25 conditions of state and 22 equilibrium types, you can be sure that Infotherm® knows the answer. Just ask us! Or query our online database yourself.
