naphthenes and aromatics

  • The water solubility of naphthenes (Journal …

    Naphthenes, like paraffins and aromatics, are a major component of unrefined fuels. Like these other hydrocarbons, naphthenes' solubility in water is of critical importance to engineers, particularly vis-a-vis the environmental hazard they present when spilled in water. Naphthenes' water solubility is described as a function of temperature. The ...

    1.1 This test method covers the determination of paraffins, naphthenes, and aromatics by carbon number in low olefinic hydrocarbon streams having final boiling points of 200 °C or less. Hydrocarbons with boiling points greater than 200 °C and less than 270 °C are reported as a single group. Olefins, if present, are hydrogenated and the resultant saturates are included in the paraffin and ...

  • Cycloalkane - Wikipedia

    In organic chemistry, the cycloalkanes (also called naphthenes, but distinct from naphthalene) are the monocyclic saturated hydrocarbons. In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring (possibly with side chains), and all of the carbon-carbon bonds are single.Cycloalkanes are named analogously to their normal alkane ...

  • Naphthenes Definition and Examples - ThoughtCo

    Naphthenes are a class of cyclic aliphatic hydrocarbons obtained from petroleum. Naphthenes have the general formula C n H 2n. These compounds are characterized by having one or more rings of saturated carbon atoms. Naphthenes are an important component of liquid petroleum refinery products. Most of the heavier boiling point complex residues are cycloalkanes. Naphthenic crude oil is more ...
