Linseed oil when percolated through a molten azeotropic salt bath, transforms into a bodied heterogeneous mass separating into two layers on keeping. This bodied oil has been fractionated by acetone into one soluble and another, insoluble, fraction. The acetone insoluble fraction has been fractionated further by applying chromatographic technique and by normal alcohols. The methyl esters of the acetone soluble and the insoluble fractions have been fractionated by urea. The analyses of these fractions suggest that the heterogeneity of the products may be caused by the interaction of oxirane and hydroxyl so as to form ethers which have thereafter undergone crosslinking under influence of the ions in the bath.
