摘要：
This work describes the synthesis and study of the antioxidant activity in mineral oils of new thiophosphorylated compound derived from cashew nut shell liquid (CNSL), a by-product of the process of improvement of cashew nuts. This study was conducted through the thermal analysis observing the T-onset variations and the accelerated oxidation experiments observing the induction time variations. The results of thermogravimetric and acceleration oxidative experiments showed a significant improvement in the oxidative stability of the doped oils. These results suggest that this new compound acts efficiently in the stabilization of the naphthenic mineral oils. (C) 2011 Elsevier B.V. All rights reserved.
