研究陰陽極組對電解丙酮的阿跺反應機構及動力現象,結果發現陰極室內DAA的生成速率較陽極室內快,而且陰陽極的反應速率與丙酮濃度皆一次反應,此縮合反應陰陽的活化能分別為45.3及90.0KJ/mol。
The mechanism and kinetics of aldol condensation of acetone by paired electrolysis were studied. The results indicate that the rate of formation of diacetone alcohol (daa ) in catholyte is faster than that in anolyte. The reaction orders in both anolyte and catholyte are first order with respect to acetone. The activation energies of aldol condensation of acetone in catholyte and anolyte are 45.3 and 90.0 KJ-mole,respectively.
