原始语种摘要: Mannich base was prepared by using pentane diamine, p-octyl phenol, and formaldehyde in existence of nitrogen gas environment. FTIR spectroscopy was used to prove the structure of the product. The behavior of the base as antioxidant for lubricant oil was examined through viscosity, acid number and density variation compared with lubricant oil sample containing no additives. A percent of 2% of the product was added to a sample of crude lubricating oil type SAE 50 furnished from Al-Dora refinery. The obtained formulation was kept under elevated oxidation conditions at 393 K, in existence of 0.1% of benzoyl peroxide as free radical initiator for oxidation process, the oxidized samples were taken at periods of 4 h up to 24 hours. The results showed that during the oxidation process, the...
