发明名称 AN INFRARED SPECTROSCOPY METHOD FOR MEASURING THE BASE NUMBER OF OVERBASED LUBRICANTS
摘要 The present invention provides a method for measuring a lubricant's total basicity by measuring one or more preselected infrared absorption bands of a lubricant and correlating the measured bands to the basicity. Preferably, the measured bands are due to carbonate or sulfate species in the lubricant.
