The paraffins are members of a series of saturated (no double bonds)
hydrocarbons with the general formula CnH(2n+2), which may be straight
chain or branched, or cyclic in which case the general formula becomes
CnH2n. They may be gases, liquids or solids at "room temperature"
depending on the molecular weight.
In the UK, "paraffin" as used for a fuel, is a crude mixture of liquid
paraffins defined as above, together with some benzene derivatives,
which account largely for its odour.
Paraffin wax belongs to the paraffin series, being a mixture
of various
higher molecular weight compounds, depending on the melting
point of the
grade.
