本文对麝香草酚蓝与盐酸小蘖碱的显色反应进行了研究，发现在pH=10.5的NH3-NH4CL缓冲溶液中显色效果最好，此反应只要在室温下就能显色完全，且稳定性好。

Nine kinds of compounds are synthesized with NTO〓, PA〓, TNR〓'used as acid radical, and CHZ, SCZ·HCl, AG·H〓CP〓 served as the materials. Among them eight kinds of compounds have been never reported in the literature and one has been prepared at home for the first time. The structures of these compounds are characterized by using the element analysis and the FT-IR measurements.
