Aniline point of high speed diesel may be about __________ °C.

ANS:B - 70

The aniline point of high-speed diesel typically ranges around 70°C. Here’s why:

1. Aniline Point: The aniline point is the temperature at which equal volumes of aniline and the petroleum product (in this case, high-speed diesel) form a single phase. It is used as an indicator of the aromatic content in diesel fuels.
2. High-Speed Diesel: High-speed diesel, also known as automotive diesel or road diesel, is a type of diesel fuel used in diesel engines for road vehicles and equipment. It is formulated to have good ignition characteristics and performance in automotive applications.
3. Temperature Range: The aniline point of high-speed diesel is typically around 70°C. This temperature is indicative of the solubility of aromatic hydrocarbons in the diesel fuel, which influences its combustion properties and emissions characteristics.
