General description

2,3-Dimethylheptane is a branched saturated aliphatic hydrocarbon. It is one of the isomer of nonane. Henry′s law constant (solubility) of 2,3-dimethylheptane has been analyzed using characteristic and counting polynomials. Its standard heat of formation, combustion and vapourization at 25°C has been calculated.

During simulation-type biodegradation tests, volatile chemicals will continuously partition between water phase and headspace. This study addressed how (1) this partitioning affects test results and (2) can be accounted for by combining equilibrium partition and dynamic biodegradation models. An aqueous
