摘　　要：对以F重烷基苯为原料的高碱值磺酸钙制备工艺进行研究,考察了各种工艺条件对产品的固体含量、过滤速度、产品收率和产品质量的影响,通过改变工艺条件及调整溶剂和促进剂用量进行优化组合实验,研究高碱值磺酸钙制备新工艺,并对比两步法、原一步法、改良一步法、新工艺等4种工艺进行实验。实验结果表明,新工艺的生产周期短,操作强度低,生产的高碱值磺酸钙产品质量合格且稳定,收率达到75.5%。The preparation of overbased calcium sulfonate was researched with F heavy alkylbenzene as material.The effects of various technological conditions on the solid content,filtration velocity,yield and quality of product were investigated.By changing the technological condition and adjusting the amount of solvent and promoter,the optimization experiments were conducted to research the preparation of overbased calcium sulfonate process of new technology,and the two-step process,the original step process,the improved one step process,and the new process technology were compared.Results indicated that the new process has short cycle and can be carried out in the low working strength;the overbased calcium sulfonate production is not only up to standard in quality but also produced in a stable way,the yield is 75.5%.
