Neutral calcium sulfonate was produced from metathesis of vacuum cut 3's paraffin base petroleum sodium sulfonate and CaCl2 ,which had calcification reaction under the effect of promoter to prepare paraffin base petroleumcalcium sulfonate. According to the investigation and analysis result of the processed raw materials ,the yield and the metal ion content,the yield of neutral calcium sulfonate after metathesis was above 95%,sodium ion content was decreased from 20 000×10-6 to 8 000×10-6,calcium ion content was increased from 12.8×10-6 to 8 000×10-6. During the metathesis process, the reaction temperature of 25%CaCl2 solution was 60℃with the 3 h reaction time,and the best reaction effect was found.
