摘要: 介绍了一种高碱性环烷酸钙的合成过程,重点考察了合成过程中促进剂、水、二氧化碳等因素对合成反应的影响,并引入了一种带有抗氧基团的辅助促进剂,得到了优化的工艺条件。结果表明:当体系中氢氧化钙加入量40%、甲醇加入量20%、助促进剂B3加入量15%、助促进剂C加入量20%、水的加入量5%、二氧化碳的通入量100% 110%时,能够合成总碱值大于等于300 mgKOH/g、钙含量大于等于10%的高碱性环烷酸钙样品。与传统的高碱性环烷酸钙产品相比,合成的样品具有更好的抗氧化安定性能。

Abstract: A synthesis technology of overbased calcium naphthenate is presented. The effect of process conditions including promoters, water and CO2 on the synthesis reactions is investigated. A co-promoter having antioxiding group is introduced and the optimal process conditions are obtained. In consequence, an overbased calcium naphthenate sample is synthesized by adding 100%~110% CO2 into a system containing 40% CaOH, 20% methanol, 15% promoter B3, 20% co-promoter C and 5% water. The obtained sample having calcium content over 10% and total base number more than 300 mgKOH/g, as compared with a conventional overbased calcium naphthenate product, said synthesized sample exhibits better antioxidation performance.
