Sulfonic acids are brown-red liquids. The lubricating oil for internal combustion engines prepared with them can effectively reduce high-temperature deposits on engine parts, effectively protect the engine for a long time, avoid acid corrosion of parts, and extend the oil change period. It has excellent high-temperature detergency and acid neutralization ability, as well as good anti-rust performance and high alkali reserve capacity.
