The effects of the four domestic heavy alkylbenzene sulfonic acid raw materials A, B, C and D on the synthesis of over based calcium sulfonate were studied. The optimum domestic sulfonic acid raw material was selected by the experiments. The feasible ratio of it to the foreign sulfonic acid raw material was sought to prepare the over based calcium sulfonate. The result showed that the domestic sulfonic acid raw materials D was the best one and the base number of over based calcium sulfonate T105 could reach 250. 2 mg/g when the mass ratio of domestic sulfuric acid D to foreign sulfonic acid was 9:1 and filtering time was 5 min. The base number of over based calcium sulfonate T106 could reach 308. 9 mg/g when filtering time was 7 min.
