Heptaldehyde
Production:
Heptaldehyde & Heptanoic acid are produced by the pyrolysis of castor oil. Heptaldehyde & Heptanoic acid are produced by the pyrolysis of castor oil.
Castor Oil is pyrolyzed in the presence of 0.5% benzoyl peroxide. The operating parameters are optimized to obtain high yields of heptaldehyde and undecylenic acid.
Ricinoleic Acid ->(pyrolysis) ->Heptaldehyde CH3(CH2)5CHO+ Undecylenic acid CH2=CH (CH2)8COOH
