ANILINE POINT (P 3, D 611, IP 2, and ISO 2977)

The aniline point is the lowest temperature at which the fuel is miscible with an equal volume of aniline and is inversely proportional to the aromatic content. High Aniline point indicates that the fuel is highly paraffinic and hence has a high diesel index and very good ignition quality. In the case of high aromatics, the aniline point of the sample will be low and have poor ignition quality. The diesel index is derived from the API gravity and aniline point
