반응 단계

To a mixture of 134 g of nonylphenol, 174 g of process oil (Mentor 28:Esso Petroleum) and 62 g of an aromatic hydrocarbon solvent (Solvesso 100: Esso Petroleum) was added 243 g of strontium hydroxide (octahydrate salt) gradually to disperse it, the mixture was subjected to reaction at 105° C. for one hour, and water was completely removed at 130° C. Carbon dioxide (10 L/hour) was blown thereinto for 5 hours to progress reaction, and the mixture was gradually heated to 155° C. to continue reaction while water was distilled off, and then filtered to give a brown solution of an overbased strontium nonylphenolate-carbonate complex (Sr=15%; metal ratio=2.9) (this product is designated S-5).
