Aniline Point & Mixed Aniline Point of Petroleum Products & Hydrocarbon Solvents

For transparent samples with an initial boiling point above room temperature and an aniline point that falls between the bubble point and the solidification point of the aniline-sample mixture, Method A is the appropriate choice.
When dealing with samples that are too dark to be tested using Method A, Method B, which utilizes a thin-film approach, is recommended.
Method C is specifically designed for samples that have a significant tendency to vaporize at the aniline point.
For samples that are prone to substantial vaporization at the aniline point, especially when only limited amounts of the sample are available, Method D is particularly suitable.
