Isolation of fully saturated glycerides from oxidation products of fats with K 2 CO 3 solution is subject to error from hydrolysis of mono‐ and diazelains to di‐ and monoglycerides respectively. Treatment of azelaoglycerides with saturated sodium bicarbonate solution does not produce detectable hydrolysis of mono‐ and diazelains and the bicarbonate insoluble fractions do not contain detectable amounts of diazelains by the sensitive insoluble calcium salt test. Procedures are available for comparison of saturated acid distributions in fully saturated glyceride and monoazelain fractions. On the basis of the above the fully saturated glycerides present in oxidation products from fats can now be accurately estimated.
