Beschreibung

Allgemeine Beschreibung

2,2,4-Trimethylpentane (TMP, isooctane) is a saturated, branched hydrocarbon. It has been reported to be nephrotoxic to male rats. Density and viscosity of TMP at various temperatures (198K - 348K) and pressures (100MPa) has been evaluated. It has been identified as nephrotoxicity inducing component in unleaded gasoline.

Anwendung

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.
