Is benzene a Naphthene?

As an aromatic hydrocarbon, naphthalene’s structure consists of a fused pair of benzene rings. It is best known as the main ingredient of traditional mothballs….Naphthalene.

Is cyclohexane a Naphthene?

Naphthenes, also known as cycloalkanes, are saturated hydrocarbons that have at least one ring of carbon atoms. They have the general formula CnH2n. A common example is cyclohexane (C6H12).

What are paraffins and naphthenes?

Paraffins – straight chain of saturated hydrocarbons. Isoparaffins – branched chain of saturated hydrocarbons. Aromatics – unsaturated hydrocarbons containing one or more benzene rings. Naphthenes – cyclic chain of saturated hydrocarbons. Olefin – unsaturated hydrocarbon containing at least one double bond.

How naphthalene is formed?

It is commercially produced by crystallization from the intermediate fraction of condensed coal tar and from the heavier fraction of cracked petroleum. The substance crystallizes in lustrous white plates, melting at 80.1° C (176.2° F) and boiling at 218° C (424° F). It is almost insoluble in water.

What is a paraffinic hydrocarbon?

paraffin hydrocarbon, also called alkane, any of the saturated hydrocarbons having the general formula CnH2n+2, C being a carbon atom, H a hydrogen atom, and n an integer. The paraffins are major constituents of natural gas and petroleum.

What is the Naphthene series?

The naphthenic series has the general formula CnH2n and is a saturated closed-ring series. This series is an important part of all liquid refinery products, but it also forms most of the complex residues from the higher boiling-point ranges.

What are asphaltenes in crude oil?

Asphaltenes are the crude oil component with the highest molecular weight. They are conditionally defined as fractions insoluble in pentane or heptane; their presence in heavy oil provides its high viscosity. Therefore, the removal of asphaltene is one of the most efficient methods for the reduction of oil viscosity.
