Aliphatic hydrocarbons in crude oil

TOTAL PETROLEUM HYDROCARONS 20 3. IDENTITY AND ANALYSIS OF TOTAL PETROLEUM HYDROCARBONS . During the refining process, crude oil is separated into fractions having similar boiling points. Naphtha ( /ˈnæpθə/ or /ˈnæfθə/) is a flammable liquid hydrocarbon mixture. Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat . In different industries and regions naphtha may also be crude oil or refined products such as kerosene.

10 facts about aliphatic hydrocarbon solvents, petroleum hydrocarbon solvents. 1. Aliphatic hydrocarbons such as alkanes, isoparaffins and alkenes are the major components of gasoline. 2. The aliphatic hydrocarbons may be of straight chain, branched or cyclic molecular structure. Some common aliphatic solvents are Mineral Spirits, petroleum naphtha, petroleum distillate, cyclohexane, octane

There are three types of aliphatic hydrocarbons. Alkanes are aliphatic hydrocarbons with only single covalent bonds. Alkenes are hydrocarbons that contain at least one C–C double bond, and alkynes are hydrocarbons that contain a C–C triple bond. Occasionally, we find an aliphatic hydrocarbon with a ring of C atoms; these hydrocarbons are called cycloalkanes (or cycloalkenes or cycloalkynes). (1) The source of the crude oil (crude oil is derived from underground reservoirs which vary greatly in their chemical composition) and (2) The refining practices used to produce the product. Due to the perceived toxicity and carcinogenic character of the aromatic hydrocarbons, the presence of these materials is carefully monitored in all areas where they might enter the human food chain.
