Density and speed of sound of four binary mixtures bromotrichloromethane + n-heptane, dibromomethane + n-heptane, bromotrichloromethane + dibromomethane, and bromotrichloromethane + bromochloromethane were measured over the entire range of composition in the temperature range from T = 293.15 K to T = 313.15 K. Excess molar volumes and deviation in isentropic compressibility have been calculated from experimental measurements and fitted to a Redlich−Kister equation to derive binary coefficients and the standard deviation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
