Hydrocarbons — Saturated, Unsaturated and Aromatic

Saturated, unsaturated, and aromatic hydrocarbons are the three principal classes of naturally occurring hydrocarbons. These classes differ in their chemical and metabolic* activities and relative abundances in organisms and sedimentary deposits.

Alkanes—saturated hydrocarbons—have relatively few important chemical properties other than that they undergo combustion and react with halogens. Unsaturated hydrocarbons—hydrocarbons with double or triple bonds—on the other hand, are quite reactive.

Analysis of saturated and aromatic hydrocarbons migrating

The hydrocarbon resins, functioning as tackifiers, were the predominant source of hydrocarbons of sufficient volatility to migrate into dry foods: the 18 hydrocarbon resins analysed contained 8.2-118 g kg(-1) saturated and up to 59 g kg(-1) aromatic hydrocarbons eluted from GC between n-C16 and n-C24, substantially more than the paraffinic waxes...

Analytical Methods for the Determination of Mineral Oil

The sulfur aromatic heterocycles may be separated from aromatic hydrocarbons by ligand exchange chromatography (LEC) using PdCl 2 and CuCl 2 on silica gel columns (see Rudzinski et al., 2005 and reference therein). Various methods have been described to separate aromatic hydrocarbons according to ring number (e.g., Radke et al., 1984).

Evaluation of mineral oil saturated hydrocarbons (MOSH) and

Aromatic Compounds. Next we consider a class of hydrocarbons with molecular formulas like those of unsaturated hydrocarbons, but which react in different ways than the alkenes. For instance, while alkenes are prone to having new atoms and groups bond across the double bond (so-called ‘addition’ reactions) these compounds do not.

The analysis of saturated and aromatic mineral oil - PubMed

After collection, mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) in dry foodstuffs and recycled paperboard were analysed using online coupled high-performance liquid chromatography-gas chromatography-flame ionisation detection (online HPLC-GC-FID) far before the end of the shelf life of the samples.
