Hydroformylation of vegetable oils: More than 50 years of technical innovation, successful research, and development

“…In the early 2000s, awareness of the depletion of fossil fuels and the subsequent increase in the oil barrel price revitalized this research sector in the wake of the 12 principles of green chemistry set forth by Anastas and Warner in 1998. Even though some recent reviews summarized works carried out in the 70s , the increasing number of recent articles dealing with the catalytic hydroformylation of fatty compounds reflects the growing interest of the scientific community in this field. Currently, the shale gas revolution poses again the problem of the profitability of bio‐based products with respect to fossil feedstock.…”

Synthesis and Functional Evaluation of Soy Fatty Acid Methyl Ester Ketals as Bioplasticizers

“…Functionalization of vegetable oils using various chemical methods such as epoxidation, alkylation, metathesis, hydroxylation, rearrangements, etc., has received ample attention because of the resulting product applications in the chemical industry [2,23]. Recently, it has been shown that hydroformylation can be used to functionalize fatty acid derivatives at the site of unsaturation, and the resulting products are useful as plasticizers and lubricants [24,25]. Similarly, the derivatives of certain functional groups such as epoxidized oils and their derivatives show promise as plasticizers as they increase the polarity and improve the compatibility with polyvinyl chloride (PVC).…”

Flame Retardancy of Bio-Based Polyurethanes: Opportunities and Challenges

“…Unsaturated double bonds along the fatty acids are oxidized first to produce aldehyde groups followed by a reduction to hydroxyl groups [71]. In hydroformylation, aldehyde groups are generated first through the reaction of double bonds with hydrogen and carbon monoxide, then are converted to hydroxyl group [72]. Another possible route to yield hydroxyl group along the fatty chain is photochemical oxidation, during which fatty acids are oxidized with sunlight source in a rich oxygen environment once exposed to high-pressure sodium-vapor lamp and tetraphenyl porphyrin as a sensitizer to produce allylic hydroperoxide [71].…”
