    摘要: Isobutane containing a significant amount of isobutylene is treated at conditions effective to oligomerize a predominance of the isobutylene, isobutane substantially free of isobutylene is separated from the oligomer products, and the isobutane substantially free of isobutylene is oxidized to tertiary butyl hydroperoxide.

    摘要: This invention is a process for producing diisobutylene from isobutylene. The process comprises first forming dry sulfonic acid resin by contacting water wet sulfonic acid resin catalyst with a first reaction feed comprising isobutylene under conditions effective to produce tertiary butyl alcohol from the reaction of isobutylene and water, and then contacting the dry sulfonic acid resin with a second reaction feed comprising isobutylene under conditions effective to oligomerize isobutylene to produce diisobutylene.

    摘要: A process for producing propylene and isoprene from a feed stream comprising 1-butene and isobutene is disclosed. The feed stream is reacted in a catalytic distillation reactor containing an olefin isomerization catalyst to produce an overhead stream comprising 2-butene and isobutene and a bottoms stream comprising 2-butene. The overhead stream is reacted in the presence of a metathesis catalyst to produce propylene and isoamylenes. Isoprene is produced by dehydrogenation of isoamylenes.

    摘要: A process for hydrogenating aqueous mixtures of 4-hydroxybutanal and 3-hydroxy-2-methylpropanal is disclosed. The process uses a metallic Pt--Ru catalyst supported on .gamma.-alumina. The process gives improved yields of 2-methyl-1,3-propanediol while minimizing the formation of unwanted by-products such as isobutyl alcohol and tetrahydrofuran.

    摘要: This invention is a process for producing diisobutylene from isobutylene. The process comprises first passing water through a downflow reactor containing a bed of sulfonic acid resin to produce an effluent stream having a pH of at least 5, then dimerizing isobutylene by contacting the sulfonic acid resin with a reaction feed comprising isobutylene and tertiary butyl alcohol. The downflow reactor comprises a bottom, an inlet located above the resin bed, an outlet located below the resin bed, and inert material in the space from the bottom of the reactor to at least above the outlet.
