Based on the fact that aniline can sensitively inhibit the decoloration of Victoria green by KIO_4 in KH_2PO_4-Na_2HPO_4 solution. The kinetic behavior of this reaction was investigated and a method for the determination of trace aniline was proposed. 基于KH2PO4-Na2HPO4缓冲介质中,痕量苯胺对高碘酸钾氧化维多利亚绿反应有阻抑作用,建立了一种测定痕量苯胺的催化动力学的新方法。
If pH4.70  ̄ 4.22, the product is P-Nitroso-N, N-dimethyl aniline, a green crystallized substance ( m. p 86 ℃). 产物有三种情况:(1)pH4.70~4.22时,产物为对亚硝基N,N-二甲基苯胺绿色结晶(m.p86℃);
