Claims13
A method for the production of 3,4,5-trihydroxycyclohexanone from quinic acid, comprising:
- oxidizing the quinic acid to 3,4,5-trihydroxycyclohexanone with an oxidizing agent selected from the group consisting of HOCL, AgNO3, (NH4)2Ce(NO3)6, V2O5, NH4VO3, and 2KHSO5.KHSO4.K2SO4/NaCl.
A method for the production of hydroquinone from 3,4,5-trihydroxycyclohexanone, comprising:
- dehydrating 3,4,5-trihydroxycyclohexanone to produce hydroquinone, wherein said 3,4,5-trihydroxycyclohexanone is prepared by oxidizing quinic acid to 3,4,5-trihydroxycyclohexanone with an oxidizing agent selected from the group consisting of HOCL, AgNO3, (NH4)2Ce(NO3)6, V2O5, NH4VO3, and 2KHSO5.KHSO4.K2SO4/NaCl.
