Effect of Type of Metals on Site Selective Dehydrogenation of Stearic Acid

Short-chain fatty acids (SCFAs) have been used as raw materials in wide range of chemical and medical applications. One technique to produce SCFAs is oxidative cleavage long-chain (LCFAs). However, unless the LCFAs are unsaturated, yield often very low because carboxylic group acid more active than other part molecule. This work explores idea introducing a double bond into saturated LCFA, i.e., stearic acid, via selective dehydrogenation using commercial heterogeneous catalysts. cracking LCFA also catalysed. Different type metals was therefore investigated study effect on dehydrogenation. The experiments were conducted an autoclave reactor under inert atmosphere. temperature 250–350°C. products analysed by gas chromatography equipped with mass spectroscopy (GC/MS). results reveal that introduction aliphatic chain possible although yields unsaturated low. Effects various parameters, such temperature, pressure, reaction time, reported.
