Carbon Dioxide → HCID 86746142, compound

Participants

Reaction Steps

41 g of anhydrous barium hydroxide was slowly added to 300 g of methyl cellosolve and dissolved therein. Next, 11 g of oleic acid and a mixture of 10 g of nonyl phenol with 36 g of an alkylbenzene solvent were added thereto followed by stirring for approximately 30 minutes. Then the mixture was allowed to react while blowing carbon dioxide into the reaction system and the temperature was slowly elevated to 150° C. while removing the water thus formed. After dehydrating and removing the methyl cellosolve under reduced pressure, overbased barium oleate/carbonate (Ba=32%, metal ratio=12) was obtained as a brown viscous product.
