| titleOfInvention | A kind of method for preparing long carbon chain dibasic acid by co-oxidation reaction |
| abstract | The present invention creates and provides a method for preparing long carbon chain dibasic acid by co-oxidation reaction. Component A, component B, aqueous nitric acid solution and catalyst are mixed and heated to complete the reaction to obtain a compound containing the desired long carbon chain dibasic acid. The reaction solution, the component A includes a cyclic alcohol with 8-16 carbon atoms, a cyclic ketone with 8-16 carbon atoms, a 1,2-dihydroxycycloalkane with 8-16 carbon atoms, and the formula One or more of the compounds shown in I, the component B includes a cyclic alcohol with 4-6 carbon atoms, a cyclic ketone with 4-6 carbon atoms and a 1 with 4-6 carbon atoms , one or more of 2-dihydroxycycloalkanes. The invention creates beneficial effects: the addition of low-carbon cyclic alcohols or ketones can play a variety of synergistic favorable factors such as inhibiting the side reaction of series decarboxylation, reducing the dosage of nitric acid, reducing the reaction temperature and reaction time, and promoting the oxidation reaction to have higher reaction selectivity , improve the yield of long carbon chain dibasic acid, greatly reduce the difficulty of separation. |
