EVALUATION OF THERMAL AND OXIDATIVE DEGRADATION OF A PHOSPHATE ESTER AND OF A NAPHTHENIC OIL
Abstract
The present work shows the study of thermal and oxidative degradation of the fluid tritolyl phosphate as well as, of a light distillated hydrotreated naphthenic oil (naphthenic oil) by spectroscopy techniques Infrared (FTIR), Thermal Analysis (TG-DTG) and an Accelerated Oxidation Test (TOA) developed in our laboratory. The degradation process was monitored by FTIR. According to the results of TG-DTG was observed that the tritolyl phosphate possess a good thermal and oxidative stability compatible with results of phosphate esters. These compounds have a good thermal stability due to the strong bond PO-Caromatic. The naphthenic oil not showed a significant thermal stability beginning its oxidation/degradation stage around 78 and 84 ° C. The degradation results of TG-DTG corroborate with the results of Accelerated Oxidation Test of the systems developed in the laboratory, making it possible to validate these results.
