Abstract
Wool-grease is deodorized by treatment with liquid sulphur dioxide. The grease may be in solution. For example, wool-grease and dioxide, charged into a pressure vessel at a temperature below -10 DEG C., and agitated together at a temperature sufficient to melt the grease, as 40 DEG C., allowed to settle and cooled to below -10 DEG C. The dioxide layer is then withdrawn. The process may be repeated or be continuous.
