| titleOfInvention | Process for synthesizing 2-ethyl-2-hexylenaldehyde through catalysis of potassium salt-solid acid |
| abstract | The invention relates to a process for preparing 2-ethyl-2-hexylenaldehyde from n-butyl aldehyde by self-condensation through catalysis of potassium salt-solid acid, which comprises the following steps: adding n-butyl aldehyde and a potassium salt-solid acid catalyst into a reaction kettle, wherein the ratio of components in the potassium salt-solid acid catalyst is as follows: the mass ratio of potassium salt to solid acid is (1-20):1, and the catalyst accounts for 0.5-15% of the mass of the n-butyl aldehyde; and reacting at 20-150 DEG C for 0.5-8 hours while stirring, and performing self-condensation reaction on the n-butyl aldehyde to obtain the 2-ethyl-2-hexylenaldehyde. According to the invention, the used potassium salt-solid acid catalyst has the advantages of high activity, favorable selectivity, no equipment corrosion, simple posttreatment and the like, and can overcome the defects of a liquid base catalyst. The maximum conversion rate of the n-butyl aldehyde can be up to 99.0%, and the maximum selectivity of the 2-ethyl-2-hexylenaldehyde can be up to 99.1%, thereby ensuring that the invention has favorable industrial application prospects. |
