Abstract :Alcohols have a long history of several uses worldwide. Because of their relatively low toxicity compared with other many chemical compounds and ability to dissolve non-polar substances, alcohols can be found into beverages for adults, used as combustion engine fuel, as excipient in medical drugs, as component into personal-care products and in many scientific and industrial applications. One of the key problems of the chemical industry is the lack of available physical properties data for equipment industrial design and improvement of theoretical models for simulation. The present work deals with the modelling and experimental measurement (density and ultrasonic velocity) of thermophysical properties of short chain hydroxylic compounds (C1-C6). Fitting equations were applied to the experimental data in order to correlate for later computer based design. Different derived magnitudes were computed from the experimentally measured density and ultrasonic velocity, due to their importance for theoretical calculations and development of new models. The estimation of the studied properties was made by the application of different theoretical procedures. A wide comparison was made with available open literature, being evident the lack of reliable information in the ranges studied until now.
