Hydroformylation

A Critical Review on the Economically Feasible and Sustainable Poly(3-Hydroxybutyrate-co-3-hydroxyvalerate) Production from Alkyl Alcohols

“…Oxo synthesis is an established process for the manufacture of alkyl alcohols at an industrial scale with simple operational requirements and low specificity in raw materials, including branched-chain, long-chain, and cyclic olefins [96,97]. It is thoroughly investigated for the production of a wide variety of industrial chemicals.…”

Nanostructured PtBi Alloy Enables Direct Oxidation of Linear α-Alcohols to Fatty Acids

“…Although efficient, this route is strongly restricted by limited feedstocks, very low natural abundance, and rare product diversity (mainly C 16 and C 18 fatty acids). 6 To circumvent these drawbacks, a shift of the raw resources to alkenes was developed, wherein fatty acids can be derived via oligomerization and hydroformylation of alkenes to aldehydes, followed by oxidation, 7 albeit the high value of alkenes renders this route less attractive. Therefore, searching alternative routes for the green manufacture of fatty acids with abundant feedstocks is highly pursued.…”

Rh-supported ionic-liquid catalysts on TiO2 for the conversion of Ethylene to propanol

“…For many years, hydroformylation has been one of t he most used processes in the industry, converting alkenes to aldehydes and other products such as alcohol and amines… This reaction can be described as the addition of hydrogen (H) and the formyl (CH) group to the olefin, which is conveniently called hydroformylation [1]. Among many considerations, rhodium and cobalt easily stand out because of their high activity and high yield of desirable products [2]. During early developments, cobalt catalysts were applied in the hydroformylation of alkenes; however, relatively harsh conditions were needed, which can be as high as 200-300 bar and a temperature of 150-180˚C [3].…”
