| titleOfInvention | Process for producing methacrolein from formaldehyde and propionaldehyde and production plant therefor |
| abstract | The present invention relates to a process and to a production plant for producing methacrolein from formaldehyde and propionaldehyde in the presence of water and a homogeneous catalyst based on at least one acid and one base. According to the invention, in order to enable the process to be carried out with a good energy balance, in which the amount of problematic waste water produced can be kept as low as possible and can be performed as simply as possible in terms of equipment, the reaction mixture is introduced into a methacrolein processing plant and is then separated therein in a first distillation column into a first distillate mixture present at the top as a gas phase and a second distillate mixture present in the bottom as a liquid phase, the first distillate mixture is then condensed and, in a first phase separator, the organic phase (first separating mixture) and the aqueous phase (second separating mixture) of the condensate are separated from one another. The second separating mixture is then fed into a second distillation column that is not part of the methacrolein processing plant, then separated into a third distillate mixture present at the top as a gas phase and a fourth distillate mixture present in the bottom and then the third distillate mixture is fed into the methacrolein processing plant. The invention also relates to a production plant with which the process according to the invention can be carried out. |
