An aldol condensation reaction of benzaldehyde with acetaldehyde and sodium hydr

Question

An aldol condensation reaction of benzaldehyde with acetaldehyde and sodium hydroxide produced cinnemaldehyde and 3-hydroxybutanal (the 3-hydroxybutanal is produced from acetaldehyde condensing with itself). If I want to use Le Chatliers principle and remove cinnemaldehyde from the product as its forming (so more cinnemaldehyde will form), how would I do that? At what temperature should I run the experiment?

Explanation / Answer

Aldol reaction between benzaldehye and acetaldehyde produced cinnamaldehyde. The product can be removed simultaneously by cooling the coutput gas stream. Cinnamaldehyde has a lower melting point than the reactants and would separate out. Thus removing product, according to LeChatellier's principle, would force the reaction towards product end, formation of more product would occur. The reaction temperature would be between 60-100 oC.
