Abstract: 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).

Abstract: Tribological study on a 12.7 mm diameter steel ball bearing specimen has been carried out in a four-ball machine. The synthesis of 3-(N-n-octadecylammonium) quinazolin-4-ones was described. The 3-(N-n-octadecylammonium) quinazolin-4-ones has been found to be quite effective as a potential ashless additive without phosphorus and sulphur in liquid paraffin according to the experimental results. Employing scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS), the film formed when the the additive interreacted with the metal was investigated.
