| titleOfInvention | A kind of catalysis reduction benzoquinone is complex compound catalyst of hydroquinone and preparation method thereof |
| abstract | The present invention relates to a kind of catalysis reduction benzoquinone is complex compound catalyst of hydroquinone and preparation method thereof.By reactant FeI 2 (CO) 3 PCy 3 It is dissolved in tetrahydrofuran solvent；O-phenylenediamine and potassium tert-butoxide are uniformly mixed, tetrahydrofuran solvent dissolving is then added thereto to, is obtained blue-violet solution；By both tetrahydrofuran solution hybrid reactions；Water is added in reaction system, and then decompression steams solvent；With n-hexane dissolution, kieselguhr filtration, drying under reduced pressure obtain complex compound catalyst Fe (CO) 2 PCy 3 (NN).The catalyst benzoquinone reduction prepares the reaction of hydroquinone and can carry out in room temperature, normal pressure, and reducing condition relaxes, it is to avoid high temperature, high pressure.With ethanol as reaction medium, without hydrogen, safe operation.Reduzate hydroquinone high income, yield reach 94%, purity more than 99%.Catalytic reaction process produces waste water seldom, pollutes without waste residue etc..Therefore, there is good prospects for commercial application. |
