Summary

9,10-Dibromo- and 9,10,12,13-tetrabromostearic acids have been isolated from the seed oil ofEremostachys moluccelloides and their structures have been established by IR, NMR, and mass spectroscopy and also by comparison with the spectral characteristics of their synthetic analogs. It has been established that byproducts can be formed from halogen-containing acids present in mixtures of acids under the conditions of generally adopted methods of isolation and separation.
