摘要：

Studies on thermal- oxidative stability of a phosphorated antioxidant, synthesized from a natural and renewable resource cashew nut shell liquid (CNSL) was investigated, using a classical thermoanalytical method-thermogravimetric (TG/DTG) in air atmosphere. Its use as an antioxidant agent on the mineral oils NH10 and NH20 was evaluated in comparative studied with a commercial product (diphenyl phosphate - Aldrich). The addition of 1.2-2.0 wt% of phosphorated cardanol compound to the mineral oils has improved their thermaloxidative stability on 14-18 degrees C, respectively. The occurrence of major thermal degradation events at higher temperatures (T-max) on additivated oils is an excellent indication of the phosphorated cardanol compound antioxidant properties.
