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

In this work, density and excess molar volume of two binary mixtures has been investigated at 298.2 K.These mixtures are 2,3-Butanediol+2-Ethyl-1-Hexanol (2,3BD+2EH) and 1,4-Butanediol+2-Ethyl-1-Hexanol (1,4BD + 2EH). Both of two systems were fitted to Redlich-Kister expression which 8 and 7 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.
