Determination of synthesis conditions of neutral calcium sulfonate, so-called detergent-dispersant
In this study, the conditions of obtaining neutral calcium sulfonate which is added to engine oils as a detergent-dispersant was studied. For this purpose, post-dodecyl benzene sulfonic acid, obtained from post-dodecyl benzene which remains as the bottom product during the production of dodecyl benzene sulfonate was used as the initial substance. Additionally, the reactor to be used in the production of neutral calcium sulfonate was designed and the amounts of spindle-oil, toluene, raw sulfonic acid solution and Ca(OH)2 used during neutralization were determined.
