Summary
A study of the glyceride composition of the oil of catalpa seeds in comparison with the well-known sunflowerseed, linseed, and tung oils which belong to the group of oils with slow, high, and superhigh drying properties, respectively, has shown that the high drying capacity of the catalpa oil is due to the specific structure of the triglycerides, namely: an exceptional affinity of the eleostearic acid of this oil for the extreme positions of the glycerol.
