摘要

lH-benzodl,2,3triazole as N-hete-rocyclic Compound was prepared by ring closure reaction of diazonium salt of o-phenylene diamine by nitrous acid.FT-IR,1H-NMR and melting point con-firmed the successful preparation of product.The main objective of this study is to observe the probability of 1H-benzodl,2,3triazole to be used as a novel antioxidant for acrylonitrile-buta-diene rubber(NBR).
