Catalytic methods for the manufacturing of high-production volume chemicals from vegetable oils and fats (review)

The Prospering of Macromolecular Materials Based on Plant Oils within the Blooming Field of Polymers from Renewable Resources

“…Those reactions mainly consist of tackling the unsaturated bonds, as in the case of epoxidation, hydroformylation, dimerization, thiol-ene coupling, oxidative cleavage (ozonolysis), olefin metathesis, pericyclic reactions, and radical additions, as well as transition-metal catalyzed and Diels-Alder syntheses to aromatic compounds [6,23,32]. Among the chemicals of interest, one finds non-exhaustively, soaps, surfactants, emollients, pesticide formulations, and lubricants [23,[31][32][33][34][35][36]. Rios and coworkers described the synthesis of new lubricant molecules from castor oil by conducting an initial step of esterification of ricinoleic acid with 2-ethylhexanol, followed by epoxidation and ring-opening of the oxirane rings [37].…”

Making natural products from renewable feedstocks: back to the roots?

“…The main application of fats and oils is the production of bio-based fuels and especially the production of biodiesel. [379][380][381] In terms of ne chemicals, plant oils have recently gained attention from surfactant and polymer science. 349,382 The number of chemical raw materials that can be produced from fats and oils is very large and these have been reviewed in depth elsewhere.…”

Methyl palmitate hydrodeoxygenation over silica‐supported nickel phosphide catalysts in flow reactor: experimental and kinetic study

“…Hydrodeoxygenation (HDO) of fatty acid‐based feedstocks (vegetable oils, animal fats, tall oils, waste cooking oils, etc.) is considered to be a versatile and effective way for producing normal alkanes – valuable components of diesel fuels . HDO of fatty acid‐based feedstocks is carried out at ca 250–350 °C and 3–7 MPa .…”

“…is considered to be a versatile and effective way for producing normal alkanes -valuable components of diesel fuels. [4][5][6][7] HDO of fatty acid-based feedstocks is carried out at ca 250-350 ∘ C and 3-7 MPa. 8 Oxygen can be removed in the form of CO (decarbonylation), CO 2 (decarboxylation) or H 2 O (direct HDO).…”

“…17,25,[29][30][31][32][33][34][35][36][39][40][41][42] Also, the reaction of ester to aldehyde (3) is included in some schemes, 17,25,[29][30][31][32][33][34][35][36][37][38][39][40][41][42] while reaction of ester to alcohol (4) is not included in any schemes for phosphide catalysts. Transesterification of ester (5) is included in one of the schemes 40 and reaction of ester to C n−1 alkene (6) 17,[30][31][32]37 or to C n−1 alkane (7) 29,33-36 is considered in several schemes. Hydrogenation of acid to aldehyde (8) and esterification of acid by alcohol (9) are generally accepted reactions, but direct hydrogenation of acid to alcohol (10) cannot be found in any scheme for phosphide catalysts.…”
