QUINOLINIUM DICHROMATE - Reference Information
| application | quinoline dichromate (QnDC) is an oxidant. The most commonly used Cr(VI) reagent is to oxidize primary and secondary alcohols to the corresponding carbonyl compounds, which can be used in laboratory research and development and chemical and pharmaceutical synthesis. |
| Preparation | Synthesis of quinoline dichromate: Quinaridine (28cm 3,0.2mol) is slowly added to a cooling solution of 20g CrO3(0.2mol) in 20 cm3 H2O. After 0.5 hours, the reaction mixture was diluted with 40cm3 of acetone and cooled to -15°C. Yellow crystals were collected and washed with acetone. It was recrystallized from H2O and dried in vacuum for about 2 h. 88% yield. Melting point 150-151 ℃. |
