What is the difference between paraffinic and naphthenic?
What is the difference between paraffinic and naphthenic?
The key difference between paraffinic and naphthenic is that paraffinic substances contain alkanes while naphthenic substances contain cyclic aliphatic hydrocarbons. The term paraffinic refers to substances containing paraffin compounds, whereas the term naphthenic refers to the substances containing naphthene.
What is 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.
What is naphthenic hydrocarbon?
1. n. [Drilling Fluids] A type of organic compound of carbon and hydrogen that contains one or more saturated cyclic (ring) structures, or contains such structures as a major portion of the molecule. The general formula is CnH2n.
What are paraffinic hydrocarbons?
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. The hydrocarbons are immiscible with water.
Which kind of oils contain asphaltic naphthenic and aromatic hydrocarbons?
Crude oil has been defined as a ‘highly complex mixture of paraffinnic, cycloparaffinic (naphthenic) and aromatic hydrocarbons, containing low percentages of sulfur and trace amounts of nitrogen and oxygen compounds'(Hawley, 1981).
What are paraffins give two examples?
Paraffins are straight- or branched-chain hydrocarbons having the chemical formula CnH2n+2. The name of each member ends with –ane; examples are propane, isopentane, and normal heptane (Figure 3.1). Figure 3.1.
What is naphthenic base oil?
Naphthenic base oil are group V base oil and are derived from sweet crude distillates by hydro-treating process at a pressure above 2500 psi. Naphthenic base oil possess low pour point, high solvency, low wax, and low aromatic content.
What is the difference between naphthenes and naphthalene?
Naphthenes are a class of cyclic aliphatic hydrocarbons obtained from petroleum. Naphthenic crude oil is more readily converted into gasoline than paraffin-rich crudes are. Note naphthenes are not the same as the chemical called naphthalene. Also Known As: Naphthenes are also known as cycloalkanes or cycloparaffin.
What is paraffinic crude?
Paraffinic crude oils are rich in straight-chain and branched paraffin hydrocarbons, whereas naphthenic crude oils contain mainly naphthenic and aromatic hydrocarbons. The composition and classification of many crude oils are obtained by ring analysis and by determination of the other constituents (Sachanen, 1950).
What is paraffinic base?
Definition of paraffin-base : containing relatively large amounts of paraffin hydrocarbons : yielding paraffin wax on refining —used especially of crude petroleum — compare asphalt-base, naphthene-base.

What is the boiling point of Nonadecane?

Nonadecane/Boiling point
What is the difference between paraffinic oil and naphthenic oil?
The aniline point of paraffinic oil is much higher than a naphthenic meaning the solvency is worse. Paraffinic oil has a high viscosity index which is good for engine oil but bad for transformers. The naphthenic oil will reach a lower viscosity meaning more oil circulation in the transformer and better cooling.
What is the boiling point of paraffin?
(Boiling range 35–140 °C) Special boiling point products are mixtures of paraffinic and naphthenic hydrocarbons with a very low aromatic content, typical value < 50 ppm.
What type of hydrocarbon is paraffinic?
Paraffinic, or alkane series, hydrocarbons are shown in Table 2.01. These hydrocarbons are typically studied in introductory courses in Organic Chemistry. Alkane series hydrocarbons are composed of only hydrogen and carbon atoms attached with single bonds.
Is paraffin a solid liquid or gas?
As a solid, the alkanes form a waxy substance, paraffin, which is the main component of such products as paraffin candles. The second category of hydrocarbon molecules found in crude oils are naphthenic (or saturated cyclic) hydrocarbons.
