【摘要】 合成了以邻异丙基苯酚为母体的9种新偶氮化合物,并对各化合物的结构做元素分析和波谱鉴定.测定了离解常数、变色域和吸收光谱特性,结果表明,这9种新偶氮化合物均有较大的摩尔吸光系数,有可能以邻异丙基苯酚为母体合成一些测定某些金属离子的良好显色剂.更多还原

【Abstract】 Nine azo-compounds have been synthesized by the reaction of o-isopropylphenol with different substitutive aromatic amine. Their structures are confirmed by elementary analysis and spectrum data. The dissociation constants are determined and diazotization conditions of different aromatic amine are studied. The results indicate that the compounds have big mole absorption coefficients from 1.4×10~4 to 5.6×10~4.Good color reagents can be synthesized with the matrix of o-isopropylphenol for determining some metal ions.更多还原
