Details:

4 - hydroxy - 2 - butanone, used for luring bark beetle powder composition, catalyst with Ziegler - tower (Ziegler - NattacatalyChemicalbookst) constitute a complex stereo specificity for butadiene polymerization catalyst and organic synthesis intermediates, is the synthetic spices raspberry ketone, acetone fennel intermediate.

The synthesis method of 4-hydroxy-2-butanone comprises the following steps:

(1) adding a certain amount of 1.3 butanediol, catalyst, water and water-carrying agent to a reaction vessel, stirring evenly to form a mixed solution, and heating up to 60-75℃;

(2) Continue to stir, add hydrogen peroxide with a mass concentration of 25-35% to the mixed solution, and steam Chemicalbook distillation and dehydration while adding drops;

(3) When the content of 1.3 butanediol in the reaction vessel is detected to be less than 5% of the initial content, stop adding hydrogen peroxide and continue to stir for 0.5-1.5h;

(4) Control the temperature in the reaction vessel and steam out the water-carrying agent;

(5) The temperature in the reaction vessel was reduced to 60-65 ° C, and the target product 4-hydroxy-2-butanone was distilled.
