Comparative Study of Yields of Heptaldehyde and Undecylenic Acid from Castor Oil and Its Derivative

Heptaldehyde and Undecylenic acid are two important by products of castor oil and their use in the industry is immense. They are derived from Castor oil. The present study compares the yields of these two compounds from castor oil and the methyl ester of castor oil. Different parameters like temperature, acid treatment, alkali treatment, temperature and presence of excess reactants were studied. Methyl Ester of castor oil produced better yields of both these compounds as compared to castor oil. The percent increase in yields of Heptlaldehyde and Undecylenic acid were 17.0371 and 13.494 at 1hour and 8.08 and 10.204 for 2 hours of incubation for castor oil and methylated ester of castor oil, respectively.
