| Abstract: |
| The applications of isovaleraldehyde and the types of isobutene hydro-formylation catalysts were simply described. The effect of by-products from the hydroformylation of isobutene such as isoamyl alcohol, isovaleric acid, and isobutane, on the yield and selectivity was studied. It was found the mass ratios of isoamyl alcohol to isobutene, isovaleric acid to isobutene, andisobutane to isobutene should be controlled below 1%, 1%, and 20%, respectively. |
| Key words: isobutene hydroformylation isoamyl alcohol isovaleric acid isobutane |
