Abstract

1,256,025. 2(21 - Hydroxyphenyl) - benzotriazoles. AGFA-GEVAERT A.G. 4 Dec., 1969 [6 Dec., 1968], No. 59188/69. Heading C2C. [Also in Division G2] Compounds of the formula where R<SP>1</SP> and R<SP>2</SP> are hydrogen or alkyl or alkoxy of up to 18 carbon atoms, at least one of R<SP>1</SP> and R<SP>2</SP> being alkoxy, and R<SP>3</SP> is hydrogen or alkyl of up to 5 carbons, are made by ring closure to form the triazole ring, e.g. the compound where R<SP>1</SP> and R<SP>2</SP> are each isopropoxy and R<SP>3</SP> is hydrogen is made by ring-closing 4 : 5-diisopropoxy - 2 - amino - phenylazo - 2<SP>1 </SP>- hydroxybenzene with CuSO 4 in ammoniacal methanol.
