사염화탄소 용액에 대하여 分光光度法으로 연구한 결과 아닐린, N,N-디메틸아닐린 및 N,N-디에틸아닐린과 요오드 또는 일염화요오드 사이에 1:1 錯物이 형성됨을 알았다. 이들 錯物형성에 대한 실온에서의 평형상수는 다음과 같다. $C_6H_5NH_2{cdot}I_2;2.05$, $C_6H_5N(CH_3)_2{cdot}I_2;15.2$, $C_6H_5N(C_2H_5)_2{cdot}I_2;35.5$, $C_6H_5NH_2{cdot}ICl;18.5$, $C_6H_5N(CH_3)_2{cdot}ICl;25.6$, 및 $C_6H_5N(C_2H_5)_2;42.0$ l $mole^{-1}$.
The systems of aromatic amines such as aniline, N,N-dimethylaniline and N,N-diethylaniline with iodine or iodine monochloride in carbon tetrachloride have been examined spectrophotometrically. The results indicate the formation of one to one molecular complexes. The equilibrium constants obtained at room temperature for formation of the complexes are as follows: $C_6H_5NH_2{cdot}I_2;2.05$, $C_6H_5N(CH_3)_2{cdot}I_2;15.2$, $C_6H_5N(C_2H_5)_2{cdot}I_2;35.5$, $C_6H_5NH_2{cdot}ICl;18.5$, $C_6H_5N(CH_3)_2{cdot}ICl;25.6$, and $C_6H_5N(C_2H_5)_2;42.0$ l $mole^{-1}$.
