The Performance and Antiwear Mechanism of 3-(N-mono-n- butylaminomethyl) Quinazolin-4-One as Additive in Liquid Paraffin
A heterocyclic derivative of 3-(N-mono-n-butylaminomethyl) quinazolin-4-one was synthesized and its tribological behavior as an ashless additve without phosphorus and sulphur in liquid paraffin 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).
