Want this question answered?
diesel index = aniline point *API(1/100)
Cetane number is derived from an engine test. It measures the ignition characteristics of diesel fuel, (which detonates under pressure). The higher the Cetane number, the greater the resistance to pre-ignition. A high cetane diesel can be used in high compression (more effcient) engines. Diesel Index (DI) is a calculation allowing an approximation of Cetane No., when there is no Cetane Test Engine available. The DI is derived from the Analine Point. The Analine Point is a temperature, where analine and the (diesel) sample become completely miscible. 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.
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
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
no
Aniline point could be improved by adding the iso-paraffin's and naphthenes in given sample of fuel oil. It could also be increased by removing aeromatics from fuel oil because high aeromatics causes smoke formation on the combustion. indirectly the cetane number is also increased by increasing aniline point.
It s the structure and bonding of Aniline, Phenol, Benzene and Toluene that causes the differences in the boiling points.
Petrol, i guess because it has a lower boiling point than diesel
Petrol has a boiling point of 38-204 degrees Centigrade, while diesel has a boiling point of >150 degrees centigrade.
A low flash point in diesel is caused by contamination of the diesel with lighter petroleum products such as kerosene or gasoline. Drawing more lighter products out of the fractionation tower could reduce contamination of the heavier products. Improving fractionation and improving diesel product stripping performance will raise the flash point.
