naphthene

noun ˈnafθiːnˈnapTHēn

Chemistry

Any of a group of cyclic aliphatic hydrocarbons (e.g. cyclohexane) obtained from petroleum.
〔化〕环烷属烃
Example sentencesExamples
- Since ethylenediamine is very polar, naphthenes are preferentially permeated to the solvent side.
- The octane numbers of alkyl-substituted naphthenes trend similarly to those of alkyl-substituted aromatics.
- Oils high in naphthene also contain more impurities such as phytotoxic aromatic and unsaturated hydrocarbons.
- Also, a higher net production of light naphthenes can be achieved for lower values of U.
- Most horticultural oils contain naphthene and paraffin compounds.

Derivatives

naphthenic

adjective nafˈθiːnɪk

Chemistry

Example sentencesExamples

- Due to the dwindling supplies of naphthenic based crude reserves, a suitable replacement oil must be found for electrical apparatus.
- Disclosed is a process for opening naphthenic rings of naphthenic ring containing compounds, and catalysts which can be used in that process.
- The results given in Figure 3 show that the oil separation is lower for the naphthenic based grease.
