aniline point is the lowest temp in f in wich equal volume of aniline and dieasel are completely missble.
Poling point is that temp in which aromatic compounds are not freezed
There is no any such difference between Aniline point and mixed Aniline point . . . . .
The aniline point of kerosene is 60-69 oC.
no aromtics show the low aniline point....because higher the aniline point higher the pariffinic content and lower the aromatic content
no
To improve the aniline point of oils, one can fractionate the oil to remove lighter components, adjust the chemical composition to increase the aromatic content, or add specific additives that can raise the aniline point. Additionally, removing any contaminants or impurities that can lower the aniline point can also help improve it.
Aniline has a higher boiling point than phenol because aniline can form strong hydrogen bonds due to the presence of an amino group. Phenol has a higher boiling point than toluene because phenol molecules can form intermolecular hydrogen bonds because of the hydroxyl group. Toluene has a higher boiling point than benzene due to the presence of a bulky methyl group which increases Van der Waals forces between toluene molecules.
Aniline can be estimated using acid-base titration. In this process, a known concentration of acid is added to a solution containing aniline until the equivalence point is reached, indicated by a color change due to the formation of a salt. This helps in determining the concentration of aniline present in the solution.
diesel index = aniline point *API(1/100)
The aniline point of vegetable oils, including coconut oil, groundnut (peanut) oil, and canola oil, typically ranges from about 30°C to 40°C (86°F to 104°F). This measurement indicates the lowest temperature at which an equal volume of aniline and the oil can mix completely. The exact value can vary based on the specific composition of the oil, including its fatty acid profile. Generally, oils with higher levels of saturated fats tend to have higher aniline points.
To distill aniline at 100 degrees Celsius, you would need to apply vacuum distillation. By lowering the pressure in the distillation setup, you can decrease the boiling point of aniline, allowing it to vaporize and distill at a lower temperature, such as 100 degrees Celsius. This technique is commonly used to separate compounds with high boiling points under milder conditions.
Diesel with a high aniline point is generally considered desirable as automotive fuel because it indicates better solvency and reduced risk of fuel system issues. Higher aniline points suggest that the fuel can better resist oxidation and thermal degradation, leading to improved engine performance and longevity. Additionally, it may provide better lubrication properties, which can enhance engine efficiency. However, other factors such as cetane number and emissions must also be considered for overall fuel quality.
liquid has deferent density at deferent temperature and so deferent volume 20 degree Centigrade is written on measuring mean that this cylinder will give accurate volume at 20 degree centigrade
