The Tribological Study of a Quinazolin-4-Ones Derivative as Additive in Liquid Paraffin
Novel heterocyclic derivative of 3-(N-n-dodecylammonium) quinazolin-4-ones was synthesized and its tribological performance when added to liquid paraffin as an ashless additve without phosphorus and sulphur was evaluated using a four-ball tester. On the basis of the experimental results, the novel additive has been found to be quite effective as a potential additive in liquid paraffin. The nature of the film on the rubbed surface was investigated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS).
