Abstract: The process method comprises forming overbased calcium sulphonate lubricating oil additives. Calcium sulphonate is produced by reacting carbon dioxide and slaked limes with heavy alkylbenzene sulphonate. Heavy alkylbenzene sulphonate is prepared from heavy alkylbenzene and filtered firstly. Carbon dioxide and slaked limes in mole ratio of 0.65-0.75 are reacted with this filtrate. So filtration performance is highly improved.
