| 摘要 |
An aldehyde-containing liquid mixture which also contains residual cobalt and/or a cobalt compound catalyst, such as an aldehyde mixture obtained by reacting an olefine with carbon monoxide and hydrogen at elevated temperature and pressure, is subjected, immediately following the production of the mixture, to a flash distillation in which the aldehyde is recovered in an overhead fraction. Condensation and/or polymerization of the product upon storage is thereby effectively suppressed. The manner in which the flash distillation may be carried out is described in the parent Specification. |
