摘要： The present invention relates to a process for producing propylene oxide comprising (I) reacting propene with hydrogen peroxide in the presence of a catalyst to give a mixture (GI) comprising propylene oxide, unreacted propene, and oxygen; (II) separating propylene oxide from mixture (GI) to give a mixture (GII) comprising propene and oxygen; (III) reducing the oxygen comprised in mixture (GII) at least partially by reaction with hydrogen in the presence of a catalyst comprising Sn and at least one noble metal.

摘要： A process for the preparation of 1,2-dichloroethane by oxychlorination of ethene in the presence of a copper-containing fixed-bed catalyst comprising a bed essentially consisting of catalyst particles which comprise, at least partially, support material impregnated with an active component and, if desired, a promoter, where the catalyst bed comprises essentially no separate inert material for dilution.
