2-Ethyl-3-hydroxyhexanal (also butyraldol ) is a chemical compound from the group of aldols .

Obtaining, displaying and using

2-Ethyl-3-hydroxyhexanal is industrially synthesized from propene . In a first step, the propene is reacted with a mixture of carbon monoxide and hydrogen in a process known as hydroformylation . This initially results in n- butanal and iso- butanal .

The 2-ethyl-3-hydroxyhexanal is produced in a further step by the aldol addition of two n- butanal molecules in an alkaline solution .
