What is the aniline point?

Aniline point is the physical characteristics of hydrocarbon compounds, such as oils, and refers to the minimum temperature at which the hydrocarbon and the same amount of compound aniline are (C _{5 NH 2 ). At temperatures below this point, the compound mixture and the same volume of anilin will not dissolve together. The test result, called aniline test, gives chemists this hydrocarbon information, including certain details of its composition, such as the relative content of aromatic chemicals and various paraffins. The volume of the test fluid and the same volume of aniline are placed together in the container, such as a tube or other laboratory vessel, and slowly heats up in gently upset. When the two liquids completely dissolve into each other, the Turns mixture from cloudy to clean. The sample is removed from the heat and mixed until it stretches again. The temperature at this point is the aniline point of this compound.}

anilin point kApalines will vary depending on the relative concentration of aromatic compounds dissolved in it. Generally higher aniline point means relatively low levels of dissolved aromatic substances. By using reference materials for a pure sample of a given substance and by comparing the anilin point of a pure sample with a test sample, the chemist can calculate the amount of aromatic substances in the test sample with a high degree of accuracy. Similar techniques and calculations can be used to determine the level of paraffin compounds present.

This data is especially important for oils that can be used as lubricants or that can come into contact with natural rubber. High oaromatic oils are less suitable for use in systems or machines that have rubber parts, because the aromatic substances gradually decompose natural rubber, which potentially causes failure in seals, seals and other components. Oil with a very high aniline point will be very low in aromatics, thanksWhich will be more suitable for use with parts, systems or machines that are made of natural or rubber products or use.
