Aniline point is defined as the temperature at which equal volumes of aniline and diesel oil are completely miscible. Aniline, phenylamine or aminobenzene is an Organic compound with the formula C6H7N Diesel or Diesel fuel (ˈdiːzəl in general is any Fuel used in Diesel engines The most common is a specific fractional distillate of petroleum Miscibility is a term commonly used in Chemistry that refers to the property of Liquids to mix in all proportions forming a Homogeneous Solution
The value gives an indication of the aromatic content of diesel oil, since aniline is an aromatic compound which is dissolved on heating by the aromatics in diesel oil. Solvation, commonly called dissolution, is the process of attraction and association of Molecules of a Solvent with molecules or Ions of a In Physics, heat, symbolized by Q, is Energy transferred from one body or system to another due to a difference in Temperature The greater the aniline point, the lower the aromatics in diesel oil. A lower aniline point also indicates a higher proportion of paraffin. In chemistry paraffin is the common name for the Alkane Hydrocarbons with the general formula C n H2 n +2
The diesel index is directly related to aniline point as:
DIESEL INDEX = ((ANILINE POINT(DEG F))(API GRAVITY))/100
A higher aniline point (and therefore a lower aromatic content) in diesel oil is desirable, in order to prevent autoignition in diesel engines. The autoignition temperature or kindling point of a substance is the lowest temperature at which it will spontaneously ignite in a normal atmosphere without an external A diesel engine is an Internal combustion engine which operates using the Diesel cycle (named after Dr
