    摘要: High purity isobutylene streams are obtained by the hydroformylation of mixed butene streams containing butene-1 and isobutylene (and optionally butene-2) under conditions that hydroformylate primarily butene-1 to yield a mixture of valeraldehyde and isobutylene, which may be separated out as an enriched isobutylene stream and used in the production of methyl tertiary butyl ether, tertiary butyl alcohol, di-isobutylene or polyisobutylene.

    摘要: Increasing the propylene content of the propylene feed delivered to a continuous hydroformylation process from the 95 mole % maximum level that is usual in typical chemical grade propylene to at least 97 mole %, for example to the 97.5% level obtainable from the conversion of oxygenates to olefins or the 99.5% level of polymer grade propylene, enables adjustments to be made in the syngas feed to the process. This leads to surprising improvements in hydroformylation product yield, in reactor capacity utilization and in the reduction of amounts of waste gases.

    摘要: Oxo-alcohols in the plasticiser range typically contain small amounts of methyl esters having the same alkyl chain as the alcohol itself. These methyl esters are causing product quality problems and environmental problems because of transesterification in the esterification process where the plasticiser ester derivatives are produced. A process using controlled oxonation and hydrogenation conditions is disclosed for the production of alcohols containing low amounts of methyl esters. Plasticiser esters with low amounts of aliphatic di-alkyl esters are also disclosed.
