The homogeneous, gas-phase formation of polychlorinated dibenzo-p-dioxins (PCDD) and polybrominated dibenzo-p-dioxins (PBDD) has been observed from the high-temperature thermal decomposition of 2,4,6trichlorophenol (2,4,6-TCP) and 2,4,6-tribromophenol (2,4,6-TBP), respectively. Experiments were cond
The standard ( p°= 0.1 MPa) molar enthalpy of formation for liquid 2,4,6-trimethylpyridine was derived from the standard molar enthalpy of combustion, measured by static bomb combustion calorimetry in oxygen, at the temperature T = 298.15 K: DfH °m = -(31.0 2 2.3) kJ•mol -1 .
A detailed quantitative analysis of the IR bandshape of the vs(OH) vibration of 2,4,6+ribromophenol in a series of solvents of varying polarity is presented. A distinct dependence of band parameters on solvent polarity has been found. Various contributions to the bandshape are discussed.
The copper(II)-catalysed polymerization of 2,4,6-tribromophenol and 2,4,6-tribromo-3-methylphenol by homogeneous and heterogeneous reaction was studied. The dependence of polymer yield and molecular weight on reaction time was investigated. The variance of bromide ion concentration in the polymeriza
