Abstract

PURPOSE: To provide the titled rust preventives having excellent rust preventing properties and discoloration preventing properties, by purifying lanolin or its derivative by column chromatography or liquid-liquid extraction.
CONSTITUTION: Purified lanolin or its derivative having free aliphatic alcohols separated and removed to a content of 2.1w% or less and having other polar compounds contained as impurities separated and removed to a content of 0.15wt% or less by treating lanolin or its derivative by column chromatography or liquid-liquid extraction. The purified lanolin or its derivative is effective as a rust preventives for nonferrous metals because its free aliphatic alcohols and polar compounds causing the rust formation and discoloring of the nonferrous metals and their alloys are removed.
