The physical properties like ultrasonic velocity, density and refractive index has been measured for the binary mixture of Carbon Tetrachloride and Toluene at different temperatures(20°C-50°C). Parameters like isentropic compressibility(Ks), acoustic impedance (Z) and Rao-number (R) are also ...
TolueneThe aim of this paper is to report experimental densities,excess molar enthalpies and refractive indexes of the ternary system (propyl propanoate+hexane+toluene) and of the corresponding binary mixtures (propyl propanoate+toluene) and (hexane+toluene) at the temperature 298.15 K and atmospheric...

It has been particularly used for determining the refractive indices and its variation with temperature for two solvents of laser dyes (toluene and carbon disulphide). Accuracy of 1×105is achieved where no uncertainity of the measurements arising from the naked eye estimation. The obtained optical...
The Molecular Dimensions of Organic Compounds. Part II. The Viscosity of Vapours: Benzene, Toluene and Cyclohexane The measurements of gaseous viscosities, which are described below, formed a part of an extensive investigation of the physical properties of some closely-related aromatic compounds; but ...
Toluene is the most common aromatic component of crude oil, followed byxyleneand benzene. Resins andAsphaltenes The resins andasphaltenesare complex compounds. They are impure hydrocarbons often referred to as NSO compounds, because they contain nitrogen, sulfur, and oxygenheteroatoms. Some of thesehet...
Poor physical conditions are a typical feature of urban soils that reduce their functionality regarding plant production or the water cycle. However, the increasing importance of urbanization makes it necessary to carry out additional research on physical properties of urban soils. Methods In this work...
Metal‒organic frameworks (MOFs) are widely studied molecular assemblies that have demonstrated promise for a range of potential applications. Given the unique and well-established photophysical and electrochemical properties of porphyrins, porphyrin-based MOFs are emerging as promising candidates for energy...
Gravimetry experiments in a well-controlled environment have been performed to investigate aging for a glassy PMMA/toluene film. The temperature is constant and the control parameter is the solvent vapor pressure above the film (i.e. the activity). Several experimental protocols have been used, sta...
