| dc.description.abstract | Additives called detergent-dispersants are among the most important components of engine oils. These prevent the corrosion of engine parts, and neutralize H2SO4, HNO3, and organic acids produced by the oxidation of hydrocarbon-based fuels. Alkyl sulfonates are one of the most widely-used detergent-dispersants. The synthesis conditions for alkali calcium sulfonate were determined. Ca(OH)2 and water were added to a mixture of neutral calcium sulfonate (NCS) and spindle oil (SO) and placed in a reactor. A CO2/air mixture was passed through the mixture at 85°C. When CO2/air mixture of 1:85 was passed through a mixture of 180 g NCS + 600 g SO + 60 g Ca(OH)2 + 90 g of water at velocity 108 L/hr for 100 min, transparent alkali calcium sulfonate was obtained with TBN of 28.6 mg KOH/g. The percentage of CaCO2 or TBN in the product increased with increasing reaction period. Prolonged reactions periods made filtration of the product difficult and increased turbidity. | |
