Triphenylmethanol is insoluble in water

Triphenylmethanol can be obtained from the Grignard reaction of phenylmagnesium bromide and methyl benzoate or benzophenone in diethyl ether.[7] Another route involves reacting triphenylmethane with chromyl chloride in tetrachloromethane at 22 °C for 30 minutes. The yield is given as 99%. Triphenylmethanol is insoluble in water, but when it is treated with concentrated sulfuric acid, a bright yellow solution results. As this yellow solution is diluted with water, its color disappears and a precipitate of triphenylmethanol reappears.
