润滑油清净剂的超重力合成过程及产品性质评定

将超重力技术原理与润滑油清净剂合成反应机理相结合，提出利用超重力反应器原位制备高碱值石油磺酸钙清净剂的新工艺，研究了超重力法原位制备高碱值石油磺酸钙清净剂的工艺流程及作用机理，并对所制备的样品进行评定，结果表明制备的样品满足SH/T 0042-1991一级品标准要求。冷冻蚀刻观测结果表明，碱性石油磺酸钙胶体结构中碳酸钙晶体的粒径为10~30nm，平均粒径为20 nm，纳米尺度效应明显，产品具有良好的透光性和流动性。

PREPARATION OF LUBE OIL DETERGENT BY HIGH GRAVITY PROCESS AND ANALYSIS OF PRODUCT PROPERTIES

Combining the high gravity technology and synthesis mechanism of lube detergent, a new route using high gravity rotating reactor to in-situ prepare overbased calcium petroleum sulfonate, a lube oil detergent, was proposed and put into practice. The properties of the detergent sample prepared by the new method well met the requirements of the first class product in Trade Standard SH/T 0042-1991. The observation results of freeze-etching replication transmission electron microscopy showed that the fine crystal particles of calcium carbonate in the alkaline colloidal structure were in the range of 10-30 nm and with an average diameter of 20 nm, which provided the product with good transmissivity and fluidity.
