Aniline point

the minimum temperature for complete miscibility of equal volumes of aniline and the sample. A product of high aniline point will be Iow in aromatics and naphthenes and, therefore, high in paraffins. Aniline point is often specified for spray oils, cleaning solvents, and thinners, where effectiveness depends upon aromatic content. In conjunction with API gravity, the aniline point may be used to calculate the net heat of combustion for aviation fuels.
