  • Publication number: 20190039991
    Abstract: Iron-based homogeneous catalysts, supported by pincer ligands, are employed in the catalytic dehydrocoupling of ethanol to produce ethyl acetate and hydrogen. As both ethanol and ethyl acetate are volatile materials, they can be readily separated from the catalyst by applying vacuum at room temperature. The hydrogen by-product of the reaction may be isolated and utilized as a feedstock in other chemical transformations.

  • Publication number: 20190039992
    Abstract: A process for preparing a variety of secondary and tertiary alkyl formate esters via the coupling of methanol and secondary (or tertiary) alcohols. Iron-based catalysts, supported by pincer ligands, are employed to produce these formate esters in high yields and unprecedentedly high selectivities (>99%). Remarkably, the coupling strategy is also applicable to bulkier tertiary alcohols, which afford corresponding tertiary formate esters in moderately high yields and high selectivities.

  • Publication number: 20180369711
    Abstract: Selective recovery of C2 to C4 hydrocarbons is achieved through the use of a converging-diverging nozzle, or de Laval nozzle. The vapor stream comprising C2 to C4 hydrocarbons is fed into an inlet of a de Laval nozzle having a throat. The vapor stream may have an initial temperature of between 0° C. and 100° C., and an initial pressure of between 200 psig and 500 psig. In the de Laval nozzle, the vapor stream expands after passing through the throat of the de Laval nozzle, producing a vapor stream having reduced temperature and pressure. Then, C2 to C4 hydrocarbons condense from the reduced-temperature vapor stream as liquid droplets, which may be recovered. Fractionation of C2 to C4 hydrocarbons by means of a de Laval nozzle is possible; the technique allows selective recovery of propane from a mixture of propane and ethane.
