Abstract
NEW MATERIAL:A benzotriazole compound expressed by the formula (A is H or acetyl; R1 is vinyl, ethyl or haloethyl; R2 is 1W4C alkyl; n is 0 or 1).
EXAMPLE: 2-(2-Hydroxy-5-vinylphenyl)-2H-benzotriazole.
USE: A raw material for a high-molecular weight ultraviolet light absorber, particularly a benzotriazole compound having a polymerizable unsaturated group or a synthetic intermediate therefo, a constituent for synthetic fibers, an additive therefor, a surface treating agent for fiber, components of a dyeing agent, components of a coat- ing agent or paints, components of a cosmetic or a medical material having weather resistance.
PROCESS: o-Nitroaniline is diazotized with a nitrite, reacted with ethylphenol and reduced to give 2-(2-hydroxyethylphenyl)-2H-benzotriazole. the ethyl group is then converted into a vinyl group.
