Description

Description générale

Palmiticacid (C16:0) is a saturated fatty acid commonly found in various naturalsources, such as animal fats and plant oils.

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.
