詳細

詳細

2,2,4-Trimethylpentane (TMP, isooctane) is a saturated, branched hydrocarbon.[1] It has been reported to be nephrotoxic to male rats.[2] Density and viscosity of TMP at various temperatures (198K-348K) and pressures (100MPa) has been evaluated.[3] It has been identified as nephrotoxicity inducing component in unleaded gasoline.[1] Single-photon absorption spectra of its pure liquid form under vacuum ultraviolet excitation have been investigated.[4] It is a reference standard employed for the octane rating system of gasoline and has been assigned octane rating of 100.6

アプリケーション

2,2,4-Trimethylpentane (TMP, isooctane) may be used to evaluate various physical properties (densities, viscosities, refractive indexes and surface tensions) of the binary mixtures of TMP and cyclohexane.[5]
