Synthesis method
1. Preparation method:
Add 10g (0.051mol) of dicyclohexylmethanol (2) and 50mL of glacial acetic acid into the reaction bottle. Slowly add 11g of chromic anhydride (0.11mol) while stirring. Maintain the reaction temperature at 20~30°C and add dicyclohexylcarboxylic acid dropwise. After adding a mixture of 22g methanol (0.112mol) and 80mL glacial acetic acid, stir and react at room temperature for 0.5h. Slowly raise the temperature to 75°C and react at 75°C for 0.5h. Cool and adjust the pH to above 10 with 20% sodium hydroxide aqueous solution. Extract with diethyl ether (50mL×3), combine the diethyl ether extracts, wash with water, and dry over anhydrous sodium sulfate. Filter, evaporate the ether, and then distill under reduced pressure to collect the fraction at 155~158℃/2.1kPa to obtain 26g of dicyclohexylmethylketone (1), with a yield of 81%. nD171.4850.[1]
