■包括N-苯甲酰苯基羟胺(BPHA)及其同系物、衍生物或同构异素物,是光度法测定钒的一类很重要的试剂。我们用1-甲基-2-萘甲酰基替换了BPHA的苯甲酰基,合成了一种新显色剂N-苯基-1-甲氧基-2-萘甲酰氧肟酸(N-phenyl
■ Including N-benzoylphenylhydroxylamine (BPHA) and its homologues, derivatives or allomers, is a very important class of reagent for the spectrophotometric determination of vanadium. We replaced the benzoyl group of BPHA with 1-methyl-2-naphthoyl group and synthesized a new color reagent, N-phenyl-1-methoxy-2-naphthoyl hydroxamic acid (N- phenyl
