Cinnamic acid withpara-hydroxy andpara-methoxy substitution has been isolated from carnauba wax in a yield of about 5%. Thepara-hydroxycinnamic acid accounts for approximately 75% of the total aromatic acids. These hitherto unreported aromatic acids occur predominantly as part of a polymerizable diester of approximate average molecular weight 1025. Certain properties of carnauba wax are believed to be due to the presence of about 30% of these diesters. Except for trace amounts, no significant quantities of these aromatic acids could be isolated in the free state from the whole wax.
