Abstrakt: A number of fats and oils and derivatives there-from were subjected to thermal diffusion in a column in which one plate was heated with low-pressure steam and the other cooled with tap water. Triglyceride moved toward the top while glycerol and monoglyceride moved toward the bottom when mixtures containing all components were diffused. Mixed triglycerides showed no tendency to separate; neither did fatty-acid mixtures which differed only in degree of unsaturation. However when a fatty acid mixture was brominated, subsequent separation was observed.
