摘要

An accurate method is proposed for the determination of lithium stearate in sebacate-base semi-fluid lubricants. The sample is treated with dilute hydrochloric acid and an extraction is performed with ethyl ether to remove diisopropyl phosphite which would otherwise interfere by causing the subsequent precipitation of lithium phosphate or lithium metaphosphate. The aqueous extract is then evaporated to fumes of perchloric acid and the lithium is determined by atomic absorption. Results are given for lithium stearate in ten samples of lubricant. The quality assurance requirements of lithium stearate used in sebacate-base semi-fluid lubricants were investigated. The following characteristics of lithium stearate were studied: moisture, melting point, lithium content, stearate content, melting point of fatty acid, iodine number of fatty acid, free acid, free alkali, pH, water-soluble matter, chloride, and granulation.
