What is the difference between Aniline Point and Mixed Aniline Point?
There is no any such difference between Aniline point and mixed Aniline point . . . . .
What is the aniline point of kerosene?
The aniline point of kerosene is 60-69 oC.
Is the aniline point highest for arromatics?
no aromtics show the low aniline point....because higher the aniline point higher the pariffinic content and lower the aromatic content
Is Aniline point is a property of lpg?
no
How can you improve aniline point of an oils?
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.
Why is it that aniline has a high boiling point to phenol and phenol has a high boiling point than toluene and toluene has a high boiling point than benzene?
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.
What is the significance of aniline point test?
The aniline point test is significant in assessing the aromatic content of petroleum products, particularly fuels and lubricants. It measures the lowest temperature at which equal volumes of aniline and the sample will mix, indicating the degree of saturation and the presence of aromatic hydrocarbons. A lower aniline point suggests a higher aromatic content, which can affect the fuel's properties, such as its combustion efficiency and emissions. This test is essential for ensuring compliance with environmental regulations and optimizing fuel performance.
Which type of titration involved in the estimation of aniline?
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.
What is the formula used in diesel index calculation?
diesel index = aniline point *API(1/100)
What is the aniline point of vegetable oil such as coconut oil groundnut oil and canola oil.?
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.
How could you get aniline to distill at 100 degrees celsius?
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.
Why does the distillate collected from the steam distillation has aniline as the bottom layer and after saturation with sodium chloride the aniline becomes the top layer?
In steam distillation, aniline, which is less dense than water, typically collects as the bottom layer due to its higher boiling point and lower volatility compared to water. However, when sodium chloride is added to the mixture, it increases the ionic strength and alters the solubility of the components. This change can lead to a phase separation where the aniline becomes less soluble in the aqueous layer, causing it to rise and form the top layer instead. The addition of salt effectively "salts out" the aniline, making it less dense than the saline water layer.
