WebThe process involves transesterification of low molecular weight carbonates, e.g. diphenyl carbonate, with quaternary ammonium functionalized alcohols, e.g. choline chloride. Preferably the reaction is run in a high dielectric constant aprotic solvent such as acetonitrile. The reaction may also be conducted neat utilizing liquefied carbonate ... WebTriphenylmethanol (also known as triphenylcarbinol and TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene. In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable "trityl" carbocation.
