Abstract
The present disclosure provides a method for forming oxygenates from olefins which includes hydroformylation of aldehydes as a formyl source alternative to syngas. In at least one embodiment, a hydroformylation process is performed at low-temperature and at or near ambient pressure for the conversion of olefins into aldehydes, thus reducing the formation of by-products such as via double bond or skeletal isomerization of the feedstock; or via further conversion of the formed aldehydes and alcohols. In at least one embodiment, the use of gaseous olefinic products (e.g., ethylene) instead of strained olefins (e.g., norbornene) improves the control equilibria in transfer hydroformylation reactions.
