摘要:
Benzotriazole UV absorbers which are substituted at the 5-position of the benzo ring by an electron withdrawing group exhibit enhanced durability and very low loss rates when incorporated into automotive coatings. This is particularly the case when the 3-position of the phenyl ring is also substituted by phenyl or phenylalkyl such as &agr;-cumyl. Compounds where the 5-position of the benzo ring are substituted by perfluoroalkyl such as trifluoromethyl are particularly of interest for both their enhanced durability and for their excellent solubility and excellent color properties in some thermoplastic compositions when the phenyl ring is substituted at the 3-position by hydrogen or tert-alkyl.

摘要:
Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain dialkylhydroxyamine stabilizers, dialkylhydroxylamine stabilizer salts, nitrone stabilizers or amine oxide stabilizers. Dyed products and articles are effectively stabilized against color degradation. The products are for example skin-care products, hair-care products, dentifrices, cosmetics, laundry detergents and fabric softeners, non-detergent based fabric care products, household cleaners and textile-care products.

摘要:
Compounds of formula I or II where R is an aryl moiety, such as phenyl, naphthyl or biphenylyl, or is phenyl substituted by one or more trifluoromethyl, bromo or cyano, and E1 and E2 are independently hydrogen, alkyl, aralkyl and the like are prepared by reaction of a benzotriazole substituted on the 5-position of the benzo ring by a halogen atom with a arylboronic acid or ester in the presence of a transition-metal catalyst, such as palladium (II) diacetate. The benzotriazole compounds of formula I are particularly efficacious as stabilizers for automotive coatings and candle wax.
摘要:
Provided is a process for preparing 2H-benzotriazole UV absorbers containing a perfluoroalkyl moiety at the 5-position of the benzo ring, for example a trifluoromethyl group, which involves diazotizing the perfluoroalkyl substituted o-nitroaniline using concentrated sulfuric acid plus sodium nitrite or nitrosylsulfuric acid to form the corresponding monoazobenzene intermediate via the diazonium salt intermediate which is reduced to the corresponding 5-perfluoroalkyl substituted 2H-benzotriazole UV absorber compound by conventional reduction means. Also provided is a novel one-pot, multiphase reaction for the preparation of 2(2-nitrophenylazo) substituted phenols, which are precursors for 2H-benzotriazole UV absorbers.
