Acid number of motor oil by endpoint titration

The Distillation of crude oil or coal tar produces high-boiling components that are commonly used as lubricationts such as motor oil.

The total acid number (TAN) is a measurement of acidity that is determined by the amount of potassium hydroxide in milligrams that is needed to neutralize the acids in one gram of oil. It is an important quality measurement of crude oil.

This application is used to determine the acid number of petrochemical products by titration with KOH in non-aqueous media. The titration is monitored by potentiometric measurement with a pH sensor and terminated at a pre-defined potential, the end point (EP).
