Rubber process oil Aniline point
All about Rubber processing oil Aniline point ASTM method : ASTM D611 and ASTM D1012
Most of petroleum products as well as RPO well known by their aniline point , especially those that are lighter, solvents used for other types of materials. Basing on the type of hydrocarbon solvent power of the crude oil is changed. Aniline point of rubber process oil has measured by a simple test and is done easily with available equipment in labratolary . In fact, this test solubility of aniline, an aromatic substance, measured in furfural extract RPO and other petroleum products.
The solubility of other substances, in fact, directly relates to the solubility of aniline. Moreover, aniline is often somewhat soluble in hydrocarbons, and its solubility in any particular hydrocarbon mixture, in turn, increases as the temperature rises. Additionally, as temperature continues to climb, the solubility becomes even more pronounced, further highlighting the relationship between temperature and aniline’s solubility in various hydrocarbon mixtures. Consequently, understanding this behavior proves crucial in applications where solubility is a key factor.
When the mixture comes complete solubility temperature for a solution is transparent, opaque mix at lower temperatures. In this method, after raising the temperature again clear solution cools the temperature at which the mixture will become cloudy measures.
The strength of aniline in hydrocarbons is greater solubility temperature at which turbidity first appears is lower. Usually, the lowest solubility for paraffinic hydrocarbons aniline (and most other substances) and therefore have higher aniline point. The highest and the lowest point of aromatic solubility of aniline (usually room temperature), respectively, whereas among paraffin naphthenic and aromatics are material.
Significance Of The Results
Aniline point is that the solvent is an indicator of strength for solvents is very important. Generally, the lower the aniline point of rubber processing oil result in higher solvent power.
Other laboratory tests actively measure the solvent power for specific materials. Two standardized and widely accepted tests are used to determine the strength of butanol solutions with pine and nitrocellulose.
However, two recent tests, more complex than the aniline point measurement, challenge small laboratories, which often lack the equipment to perform them. Despite this, the tests usually provide better communication with specific applications. In hydraulic and lubricating oils, the aniline point indicates how likely the oil is to soften and swell rubber parts that come into contact with it.
The lower aniline point, you tend to swell out more. Aniline point is also a factor in determining the relative consistency of rubber, soft rubber formulations used.
