ABSTRACT:
A process for the preparation of sulphurized calcium phenate from cashew nut shell liquid (CNSL). Distilled or hydrogenated distilled CNSL is reacted with calcium salt and sulphur in the presence of promoters to obtain a reaction mixture. The reaction mixture is subjected to the step of carbonation to obtain basic sulfurized calcium phenate, which may be subjected to a further step of basefication to obtain overbased sulphurized calcium phenate. Such a calcium phenate is added to lubricating oil or grease as an additive.
