Thin layer chromatography with silica gel was applied to 15 oil-soluble dyes (Table 1) and 12 solvents (Table 2) have been studied as developer.
The results obtained were as follows:
1) Azobenzene, p-aminoazobenzene, Butter Yellow, p-methoxyazobenzene, p-hydroxyazobenzene, Sudan G could be separated by dichloroethane (1, 2).
2) Oil Yellow AB and Oil Yellow OB could be separated by xylene or pentachloroethane.
3) Sudan III, Sudan IV and Oil Red OS could be separated by dichloroethane, chloroform or trichloroethane (1, 1, 2) respectively.
4) Quinoline Yellow SS could be separated from above-mentioned dyes by chloroform.
