Abstract

The preparation of (Z)-9-tetrardecenoic acid from beef tallow was assessed. Over one kilogram of this acid was obtained, in high purity, by a stepwise procedure involving fractional distillation, low temperature crystallization from acetone and fractional crystallization. Confirmation of the structure of the isolated acid methyl ester was achieved by reductive ozonolysis and IR spectra. This ester was uti1ized as starting material for the preparation of (Z)-9-tetradecenol an expected sex pheromone of the fall army worm. Other pheromones; (Z)-9-tetradecenyl acetate and (Z)-9-tetradecenyl aldehyde were prepared. The three compounds are now being tested in the field as sex attractants.
