| titleOfInvention | A kind of method that 5 hydroxymethylfurfural prepares 2,5 furandicarboxylic acids |
| abstract | 2 are prepared the invention discloses a kind of 5 hydroxymethylfurfural, the method of 5 furandicarboxylic acids, with molybdic acid quaternary ammonium salt and wolframic acid quaternary ammonium salt as catalyst, oxygen, hydrogen peroxide or air are oxidant, 80 120 DEG C are heated under alkaline environment, 5 hydroxymethylfurfurals are selectively oxidized.It is of the invention to utilize ammonium salt and molybdic acid or wolframic acid structure regulating catalyst activity and selectivity of product, easily used catalyst activity height, recovery and good stability；The oxidant that oxidizing process is used is environment-friendly, green non-pollution, can just obtain at low temperature 2,5 furandicarboxylic acids in high yield and high selectivity, the conversion ratio of 5 hydroxymethylfurfurals reaches more than 90%. |
