Abstract

1417072 Monoazo compounds CIBAGEIGY AG 10 July 1973 [11 July 1972] 32896/73 Heading C4P Azo compounds of Formula I where R<SP>1</SP> and R<SP>2</SP> are independently alkyl, cycloalkyl, aralkyl or chlorine, R<SP>3</SP> is hydrogen, chlorine, alkyl, alkoxy, alkylsulphonyl, acylamino, -SO 3 H or -COOH and R<SP>4</SP> is hydrogen or chlorine are prepared by reacting an aqueous solution of a diazonium salt of an amine of Formula II the aqueous solution containing an inorganic acid and having a pH less than Z, with a phenol of Formula III dispersed in water. The reaction is preferably carried out at 0‹ to 60‹ C. The phenol may be completely or partly dispersed in water and the dispersion may be produced by adding dispersing agents to the water. The compounds of Formula I are used as intermediates in the preparation of benztriazole light protection agents.
