Aniline point is an indicator of chemical composition of motor
gasoline and diesel fuel and of their aromatic and paraffinic contents
in particular. A significant relationship between the research octane
number of unleaded motor gasoline and its a
niline point was
investigated. This relationship was evident in particular in the case
of aromatic and naphthenic compounds with higher octane numbers.
A correlation equation with a correlation coefficient of 95% was
found with an acceptable average error.
