Abstract

In this study, alkali calcium sulfonate which is added to engine oils as a detergent‐dispersant was obtained. A definite amount of Ca(OH)2 and water was added to the mixture of neutral calcium sulfonate (NCS) and spindle‐oil (SO), and the mixture was taken into an appropriate reactor. CO2‐air mixture was passed through the mixture for definite periods at 85°C and the appropriate parameters affecting the qualities and efficiency of the product were determined. Thus, after the mixture of CO2+air (having the ratio of 1/8.5) was passed through the mixture of 180 g NCS+600 g SO+60 g Ca(OH)2+90 g water with the velocity of 108 L/h for 200 min, transparent alkali calcium sulfonate with a total base number value of 28.6 mg KOH/g was obtained.
