Method for producing adipic acid and dibasic acid by using nitric acid to oxidizing cyclohexane bionic oxidation mixture
The invention relates to a method for directly preparing adipic acid and diacid from cyclohexane bionic oxidation mixture by nitric acid oxidation. The invention is characterized in that in the presence of 1-10mg/L metalloporphyrin catalyst, at 140-160DEG C and 0.8-1.2MPa, cyclohexane is oxidized by...

| description | The invention relates to a method for directly preparing adipic acid and diacid from cyclohexane bionic oxidation mixture by nitric acid oxidation. The invention is characterized in that in the presence of 1-10mg/L metalloporphyrin catalyst, at 140-160DEG C and 0.8-1.2MPa, cyclohexane is oxidized by air, and the cyclohexane oxidation mixture is directly prepared into adipic acid and diacid by nitric acid oxidation. Compared with prior adipic acid preparation, the invention can simultaneously improve single-pass conversion of cyclohexane and total yield of diacid respectively more than 10% and 80%. At the same level of adipic acid yield, the circulation quantity of cyclohexane is reduced more than 50%, nitric acid consumption is reduced about 10%, to reduce the load on cyclohexane distillation system, reduce energy consumption, and reduce production cost. The invention can be directly used in prior industrial unit that prepares adipic acid from cyclohexane, to reduce production cost and improve yield. The inve |
