| titleOfInvention | Method for catalyzing low-carbon aldehyde aldol self-condensation reaction by acid-base bifunctional ionic liquid |
| abstract | The invention relates to a method for catalyzing low-carbon aldehyde-aldol self-condensation reaction by using an acid-base bifunctional ionic liquid. The method comprises the following steps: adding a low-carbon aldehyde and acid-base bifunctional ionic liquid catalyst into an autoclave, reacting for 1-12h at 60-150 ℃, and carrying out aldol self-condensation reaction on the low-carbon aldehyde to obtain long-chain unsaturated aldehyde; the acid-base bifunctional ionic liquid is acid-base bifunctional ionic liquid with anions and cations respectively containing acid-base groups, or novel acid-base bifunctional ionic liquid with cations having acid-base groups. The invention is applied to the aldol self-condensation reaction of n-butyraldehyde and n-valeraldehyde, the reaction condition is mild, the catalytic activity is high, the selectivity is good, and the acid-base bifunctional ionic liquid catalyst can be reused. |
