| titleOfInvention | Improved method for synthesizing acrolein from glycerol |
| abstract | The present invention relates to a method for synthesizing acrolein, coupling the dehydration of glycerol into acrolein using a reaction for condensing aldol from acetaldehyde, produced in the impure state during dehydration, by means of formaldehyde. Specifically, the method according to the invention involves subjecting the gaseous effluent from the glycerol dehydration reaction to cooling, then proceeding firstly, in a first area, to water cleansing and condensation of said gaseous effluent so as to then separate, in a second fractionation area, firstly, a light aldehyde-rich flow from, secondly, a water-rich flow and, thirdly, the acrolein flow and then reacting the acetaldehyde, contained in the light aldehyde-rich flow from the previous step, with formaldehyde so as to obtain a second acrolein-rich flow by means of an aldol condensation reaction according to the following reaction diagram: CH 3 -CHO + CH 2 O ⃗ CH 2 =CH-CHO + H 2 O; and recirculating said second acrolein-rich flow into the previous step. |
