✦ Synopsis

SUMHARY A series of reactions was elaborated for the transformation of 1,2,3-trimethoxybenzene into pllic acid-14C02H. The intermediate l-bromo-3,4,5trimethoxybenzene was prepared by nitration, reduction, diazotization, and decomposition of the diazonium salt in the presence of cuprous bromide. The halide-exchange reaction of the aryl bromide with butyl lithium, decomposition of the intermediate lithio derivative with 14C02, and demethylation, led to gallic a ~i d -~~C o ~H .

## Abstract Aqueous solutions of gallic acid have been treated with five different oxidation‐radiation processes: visible and ultraviolet A radiation (VUVA), TiO~2~ adsorption, ozonation, VUVA/TiO~2~ photocatalysis and VUVA/O~3~/TiO~2~ photocatalytic ozonation. With the exception of VUVA radiation
