摘　　要：合成了 BTADCAB、5,6-Cl-BTADCAB、BTADCABS和 5,6-Cl-BTADCABS4种新显色剂 ,试验了试剂与金属离子的显色反应 ,发现含有— SO3H分析功能团的 BTADCABS和 5,6-Cl-BTADCABS仅与 Pd2 +起显色反应。Four new color reagents,BTADCAB,5,6ClBTADCAB,BTADCABS and 5,6ClBTADCABS were synthesized and their acidity constants were determined by using spectrophotometric method.Color tests of the four reagents with twentynine kinds of metal ions indicated that 8 metal ions gave color reactions with BTADCAB and 5,6ClBTADCAB,only one metal ion,Pd 2+ reacted with BTADCABS and 5,6ClBTADCABS.
