2-Ethylhexanol synthesis

11synthesis methods
2-ethylhexanol synthesis: Condensation of acetaldehyde into butanol aldehyde, dehydration to obtain crotonaldehyde, hydrogenation to n-butyraldehyde, condensation dehydration to obtain 2-ethyl-2-hexenal, and then hydrogenation to obtain 2-ethylhexanol.

Yield:104-76-7 96%

Reaction Conditions:

with hydrogen at 110; under 18751.9 Torr; for 28 h;Inert atmosphere;

Steps:

2.2

The hydrogenation reaction was performed by using the loop reactor with the same method to Example 1.3.1 except supplying 96% ethylpropylacrolein reaction product produced from Example 2.1 in a rate of average 4.7 kg per 1 hour, along with hydrogen in a rate of 0.26 kg per 1 hour.While the liquid level was maintained, after reaching the normal state, the driving was continuously performed for 28 hours thereby obtaining 136 kg of the total weight of the hydrogenation reaction product having octanol as a main component in a rate of average 4.86 kg per 1 hour.From analyzing the components through the gas chromatography, butanol was 0.5%, octanol was 96%, a heavy component, such as butylaldehyde trimer, was 3.3%, and water was 0.2%.
