METHOD OF OBTAINING 3,4-DIACETYL HEXANE-2,5-DIONE

摘要

The invention relates to a process for preparing 3,4-diatsetilgeksan-2,5-dione, which is used as a chelating agent, a complexing agent, intermediate in the synthesis of heterocyclic compounds and acetylacetone, and also for the preparation of detergents, wetting agents and polymeric materials. The goal - improving the yield. 3,4-Diatsetilgeksan-2,5-dione obtained by oxidation of acetylacetone under electrolysis conditions in a non-diaphragm electrolysis at the cathode and anode in the presence of an electrolyte - sodium iodide in acetone at 0-10 & amp; deg; C by passing 1.6-2, 0 F electricity per 1 mole of acetylacetone. The method allows to obtain the desired product with a 80-92% yield of Table 2.
