Study of Density and Excess Molar Volume of Two Binary Solutions, (2,3-Butanediol+2-Ethyl-1-Hexanol) AND (1,4-BUTANEDIOL+2-ETHYL-1-HEXANOL) AT T=298.2 K

摘要

In this work, density and excess molar volume of two binary mixtures has been investigated at 298.2 K.These mixtures are 2,3-Butancdiol+2-Ethyl-1-Hexanol (2,3BD+2EH) and 1,4-Butanediol+2-Ethyl-1-Hexanol (1,4BD + 2EH). Both of these systems were fitted to Redlich-Kister expression which 8 and 6 degree of polynomial expansion were obtained for 2,3BD + 2EH and 1,4BD + 2EH, respectively .The standard deviation was calculated and reported for both of them.
