Abstract:
Opal and opal oleate with aniline contents of less than 500 parts per million are prepared by dissolving opal in sulfuric acid and recrystallizing. The recrystallized opal is converted to opal oleate using oleic acid. The opal oleate with low aniline content finds application in the specialty colorants field.
