A kind of method for preparing cyclocitral from C10 unsaturated aldehyde distillation column still liquid |
| abstract |
A method for preparing cyclocitral from the still liquid of a C10 unsaturated aldehyde rectification tower, specifically comprising the steps of: uniformly mixing a solvent A and a C10 unsaturated aldehyde rectifying still liquid to obtain a solution A of a rectification by-product, and then adding a catalyst B , at a certain temperature, the rectification by-product is subjected to dehydration reaction; the reaction product of the dehydration reaction is separated to obtain C10 unsaturated aldehyde and cyclocitral; the obtained product cyclocitral has a high yield, and the product is colorless and transparent without decolorization. . |
