| 摘要 |
This invention relates to a process for producing active carbonyl compounds predominating in aldehyde groups from polybutenes having at least 50% of the unsaturation in the terminal position. The process has an initial epoxidation of the polybutene followed by isomerisation of the epoxide so formed at a relatively higher temperature. The active nature of the carbonyl group enables these compounds to be readily converted to the corresponding amines or imines which are useful fuel and lube oil additives.
