An aromatic carbonate having the formula: ##STR1## wherein R' is alkyl and R is alkyl, alkoxy, aryl, aryloxy or NO.sub.2, is prepared by reacting the related phenol or an acyl ester thereof with an alkyl, cyclic or aryl-alkyl carbonate in the presence of a catalyst such as AlCl.sub.3.

Process for the preparation of aromatic carbonates

An aromatic urethane (e.g., methyl naphthyl urethane) is prepared by reacting an aromatic hydroxy compound, such as alpha-naphthol, with an aliphatic urethane, such as dimethyl urethane, in the presence of a catalyst consisting of a Lewis acid.
