摘要: 采用多步法合成高碱值磺酸钙,研究了不同来源的磺酸原料、国产磺酸与进口磺酸不同配比、加水量和CO2通入速率、甲醇加入量等因素对合成高碱值磺酸钙性能的影响。结果表明:合成高碱值磺酸钙最佳条件为进口磺酸与国产磺酸D质量比1:9,加水量2.5 g,CO2通入速率400 mL/min,甲醇加入量26 mL;以国产磺酸D为原料合成的高碱值磺酸钙产品易过滤、总碱值较高、浊度和运动黏度较低。

Abstract: The high alkaline calcium sulfonate was prepared by multistep method using acid materials from different sources. The parameters of ratio of domestic and foreign sulfonic acids, the amount of water added, the flow rate of carbon dioxide and the volume of methanol were changed to test the effect on the performance of the sulfonate products. The results showed that the best systhetic conditions are: the ratio of domestic sulfonic acid D and foreign one of 9:1, water 2.5g, CO2 flow rate 400ml/min, dosage of methanol 26ml. At these conditions, the obtained sulfonate has a high TBN, low turbidity, low motion viscosity and the product is easy to filter.

Key words: high alkaline, calcium sulfonate, sulfonic acid
