| Abstract: | Synthesis of adipic acid based on cyclohexene in phase transfer catalyst was investigated with 30% H2O2 as oxidant,complex compound formed by Na2WO4·2H2O as catalyst.The effects of catalyst dosage,ratio of Na2WO4·2H2O to H2O2,ligand dosage,phase transfer catalyst dosage and reaction time on reaction were studied.The results showed that the max yield of adipic acid was 67.4% when phosphoric acid was used as the ligand,PEG600 as the phase transfer catalyst and the molar ratio of Na2WO4·2H2O,H3PO4 and cyclohexene was 1∶2∶20.Although the aqueous solution of Na2WO4·2H2O and H2O2 was used for 5 times,the separation production rates were still high.The solution of Na2WO4·2H2O and H2O2,a kind of green catalyzed oxidation system,has good prospects for development.. |
