ABSTRACT:
In the preparation of an overbased calcium sulfonate, it has been found that charging calcium oxide and the total amount of water in amount of water of 20 to 25 mole % of the calcium oxide and a calcium oxide:calcium hydroxide ratio of 60:40 before carbonation improved feedstock utilization and reduced solids. Calcium hydroxide may be mixed with the calcium oxide through it takes no part in the water requirement.
