ABSTRACT:
The partial alkylation of a polyhydroxybenzophenone having ortho- and para-hydroxy substituents to form an ortho-hydroxy, para-alkoxy benzophenone is carried out in the presence of a non-aqueous solvent, viz. a polyethylene glycol or its mono or dialkylated derivatives, whereby high yields of alkylated product are obtained in shorter reaction times.
