Isentropic compressibilities K-S, and thermal expansion coefficients alpha for methyl methacrylate, 1,2-dichloroethane (DCE), 1,1,2,2-tetrachloroethane (TCE), 1-chlorohexane, and 1-bromohexane in the temperature range 298.15-333.15 K and isentropic compressibilities K-S(E), excess molar volumes V-E for 14 binary mixtures of methyl methacrylate (MMA) with hexane, cyclohexane, benzene, toluene, chlorobenzene, tetrachloromethane, trichloromethane, 1,2-dichloroethane, 1,1,2,2-tetrachloroethane, 1-chlorohexane, 1-bromohexane, n-propylamine, n-butylamine, and tri-n-butylamine over the entire range of composition at 303.15 K, derived from experimental densities rho and speeds of sound u have been reported. The values of K-S(E) and V-E for 14 binary mixtures indicate varying extent of molecular interactions and interstitial accommodation between unlike components. The experimental speeds of sound have been analyzed in terms of collision factor theory (CFT) and free length theory (FLT). (C) 2003 Elsevier Science B.V. All rights reserved.
