Description

Application

Palmitic acid may be employed in the preparation of palmitic anhydride, via reaction with dicyclohexylcarbodiimide (DCC) in carbon tetrachloride. It undergoes deoxygenation in the presence of 4%wt Pd/C mesoporous catalyst at 300°C and pressure of 17bar of 5% H2 in argon. Aliphatic chain length hydrocarbons containing one less carbon than the corresponding acid were obtained as major products.
