Synthesis of 8-heptadecene by decarboxylation of oleic acid in various catalyst systems

Decarboxylation of Diunsaturated Linoleic Acid to Heptadecane over Zeolite Supported Pt/ZIF-67 Catalysts

“…Hydrodeoxygenation is the most developed process but requires a large supply of hydrogen, which incurs large costs, safety concerns, and negative environmental impacts. , Decarboxylation is an effective alternative which results in the removal of the carboxylate group as carbon dioxide, leaving linear hydrocarbons such as heptadecane (C 17 ). Fatty acid deoxygenation has been widely studied over diverse solid catalysts, including Pt/C, SiO 2 , CeO 2 , zeolites and hydrotalcite, SAPO-11 and chloride Al 2 O 3 , Pd/C, activated carbon, metal nitrates, metal nitrides, supported on γ-Al 2 O 3 , hydrotalcite, Sn hydroxide, Fe, Ni/MgO-Al 2 O 3 , H 3 PO 4 /Al 2 O 3 , and aluminosilicate, titanium, magnesium, zirconium and cerium oxide …”

“…Several studies of the decarboxylation of the unsaturated oleic acid have been documented. 5,[17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] Representative examples include Pt-Re/C, 21 Pt/C, 21,25 Pd/C, 22,23,25 molybdenum nitrate, tungsten nitride and vanadium nitride supported on γ-Al 2 O 3 , 24 Pt/SiO 2 , 25 hydrotalcite, 26 Ni/MgO-Al 2 O 3 , 27 H 3 PO 4 /Al 2 O 3 , 28 Ru/CeO 2 ,16 Pt/CeO 2 , 29 natural aluminosilicate and nano-sized titanium and magnesium oxide. 30 In most of these reports, the support is a catalytically inert material like carbon or relatively, non-acidic components, like silica or non-acidic alumina.…”
