Abstract
New superbasic detergent additives are manufactured in two steps. The first step comprises the reaction of a sulfonic acid with an excess of oxide or hydroxide of lithium or group II A metal. The second step consists of carbonating the oxide or hydroxide in excess. The manufacture is conducted in the presence of a polyalkenylsuccinimide-amine salt.
