    摘要: Embodiments of the present invention relate to processes for converting olefins to alcohols, ethers, or combinations thereof that are suitable for use as a gasoline additive. In one embodiment, the process comprises (a) receiving a feed stream, wherein the feed stream comprises one or more olefins having 2 to 5 carbon atoms in an amount of up to 80% by weight based on the weight of the feed stream; (b) hydroformylating the feed stream in the presence of a catalyst to convert at least 80% of the olefins from the feed stream to oxygenates; (c) separating a product stream from step (b) into an oxygenate stream and a stream comprising unreacted olefins, inerts, the catalyst, and the remaining oxygenates; and (d) treating the oxygenate stream to convert a plurality of the oxygenates into at least one of an alcohol, an ether, or combinations thereof having at least 3 carbon atoms, wherein at least 25 weight percent of the alcohols and ethers having at least 3 carbon atoms are branched based on the total weight of the alcohols and ethers having at least 3 carbon atoms, and wherein the alcohols, ethers, or combination thereof is suitable for use as a gasoline additive.

    摘要: Some embodiments of the present invention relate to processes to recover rhodium from a hydroformylation process. In some embodiments, the process to recover rhodium from the hydroformylation process comprises (a) treating a catalyst-containing stream from the hydroformylation process with 2.5 to 20 weight percent, based on the total weight of the stream, of a water-soluble organic amine of the following structure: wherein R32, R33, and R34 are each independently alkyls and ethoxylates, and wherein no more than one of R32, R33, and R34 is alkyl; (b) heating the resulting solution in the presence of syngas to a temperature of at least 65° C. to generate a rhodium-rich phase and a supernatant; and (c) removing the supernatant to recover the rhodium-rich phase.
