Assuntos Gerais Volumetric and Thermodynamic Properties of Pure Substances and Their Mixtures
Quim. Nova, Vol. 31, No. 7, 1901-1908, 2008 OTTO REDLICH: CHEMIST AND GENTLEMAN FroM the “OLD SCHOOL” Simón Reif-Acherman Escuela de Ingeniería Química, Universidad del Valle, A. A. 25360 Unicentro, Cali - Colombia Recebido em 7/9/07; aceito em 22/4/08; publicado na web em 3/10/08 The name of Otto Redlich is generally remembered as co-author of one of most used equations of state for the calculation of Assuntos Gerais volumetric and thermodynamic properties of pure substances and their mixtures. Nevertheless, he made also important contributions in different areas of chemistry and chemical engineering. Pursuits of race and religious order forced him and his family to leave his native Austria and emigrate to the United States. His professional career included both academic and industrial research achievements. Keywords: Physical chemistry; thermodynamics of solutions; Raman spectroscopy. INTRODUCTION Practically every day students and professionals of all disciplines in science and engineering use theories, equations, and rules, baptized with the names of those scientists who derived them. A quick survey among a representative sample of such students and professionals very surely would reveal that, with few exceptions, not many would have at least a minimum knowledge about the persons who are responsible for these scientific contributions. The Redlich-Kwong equation of state has been used for several generations of chemists and chemical engineers for the calculation of volumetric and ther- modynamic properties of pure substances and their mixtures, being preferred nowadays because of its simplicity and acceptable degree of Figure 1.

Jacob Bigeleisen 1919–2010
Jacob Bigeleisen 1919–2010 A Biographical Memoir by Alexander Van Hook ©2014 National Academy of Sciences. Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. JACOB BIGELEISEN May 2, 1919–August 7, 2010 Elected to the NAS, 1966 Jacob Bigeleisen did seminal work in the 1940s on the effect of isotopic substitution on chemical equilibria and on isotope separation. For some 60 years thereafter he continued with studies of isotope effects on chem- ical kinetics, reaction mechanisms, and molecular and condensed phase properties, isotope effects in geochem- istry, and refinements to the theory of isotope separa- tions. Consequently his theoretical contributions have had an enormous effect on a number of areas of research. For example, the use of kinetic isotope effects to deduce mechanistic paths and transition state structures is now a major research tool in organic chemistry, biochem- istry, and enzymatics, with hundreds of papers appearing By Alexander Van Hook1 each year. Professor Bigeleisen’s efforts, however, were not constrained to theory alone. He was responsible for a series of insightful experimental studies involving the effect of isotope substitution on condensed-phase properties of the rare gases, on a number of H/D substituted hydrocarbons, and on other molecules. Bigeleisen also played a key role in the development of most of the important isotope separation processes employed by the U. S. Department of Energy and its predecessor, the Atomic Energy Commission. Finally, Bigeleisen was extremely active in service to his profession, to university adminis- tration, to the National Academy of Sciences, and to the Gordon Research Conferences. -
