Aniline point is a property that is typically associated with gasoline. Here's an explanation:

1. Definition: Aniline point is the temperature at which equal volumes of aniline (a colorless, oily liquid with a fishy odor) and a petroleum product, such as gasoline, form a single phase. It is used as an indicator of the aromatic content of the petroleum product.
2. Measurement Significance: Gasoline, being a refined petroleum product, contains varying levels of aromatic hydrocarbons. The aniline point helps to assess the solubility and miscibility of these aromatics with aniline, which is indicative of the product's composition.
3. Applications: Aniline point is particularly relevant in the refining and quality control of gasoline, where the content and composition of aromatics affect the fuel's performance characteristics, such as octane rating and combustion behavior.
