Synthesis lines:

 there are several main synthetic methods for 2,5-hexanedione (110-13-4):

Preparation by hydrolysis of 2,5-dimethylfuran

2,5-dimethylfuran is hydrolyzed under dilute acid conditions (such as sulfuric acid) to form 3-ene-2,5-hexanedione, which is then reduced by hydrogenation to obtain 2,5-hexanedione

The yield can reach over 80%

Reaction method of sodium ethyl acetate with iodine

Sodium ethyl acetate reacts with pure iodine to produce diethyl diacetate;

Then hydrolyze with 10% sodium hydroxide, neutralize, extract with ether, and distill (collect fractions at 192-194 ℃) to obtain pure product

Oxidation open-loop method (Shenk method)

2,5-dimethylfuran undergoes ring opening oxidation to obtain 3-ene-2,5-hexanedione;

Subsequently, it undergoes catalytic hydrogenation reduction to 2,5-hexanedione
