METHOD FOR SEPARATING A LIQUID CRUDE ALDEHYDE MIXTURE BY DISTILLATION |
摘要 |
<p>In a process for the fractional distillation of a liquid crude aldehyde mixture including straight-chain and branched aldehydes, the product mixture is fractionated in a first distillation column to give a product stream of branched aldehyde, a product stream of straight-chain aldehyde and a further product stream including straight-chain aldehyde and the high boiling constituents. The further product stream is then fractionated in a second distillation column whose packing volume is a factor of from 50 to 200 smaller than that of the first distillation column to give a product stream of straight-chain aldehyde and a high boiler product stream.</p> |
