Benzalkonium chloride which is widly used as medicine is nitrogen Compound of quaternary amines. In this thesis, the author investigated the application of extraction method of organic solvents in forming ion pair between benzalkonium chloride(BKC) and metanil yellow(MY). In the process of laboratory work, MY and BKC were mixied and added the buffer solution to 10㎖, and then the solution was shaken for 5 minutes. Dichlormethane was the best of all other solvents as than dichlormethane, chlorobenzene, benzene, nitrobenzene and carbontetrachloride in the extraction solvents of ion pair which was formed between MY and BKC.
However, MY has never been extracted with any kinds of solvents either. Bu using the method of continuous variation, the authors investigated that the mole ratio of reaction products formed between MY and BKC was 1 : 1 ratio. In this experiment, the maximum absorption wavwlwnth of the reaction product was 402㎚. Dichlormethane was the best extracting solvent among the serveal organic solvents and the most suitable pH range was 2∼8. When the BKC-MY calibration curve was in the best experimental condition, the Lambert-Beer's law was obeyed in the range of BKC of 2×10^-6 M by UV spectro photometer.
