영문 초록

Distribution coefficients between nitrobenzene solution and deionized water, show a straight line when the number of alkyl radicals against the logarithm of distribution coefficient of the salts was plotted. After extracting salts of the indicator and the cationic surfactants with organic solvents, and employing the calorimetric method was used. A calculation method of distribution coefficients of the salts in the organic solvent has been suggested and it could be used for the extraction equilibrium of the primary amine, CH3(CH2)nNH3+, secondary amine, CH3(CH2)nNH2(CH3)+, tertiary amine, CH3(CH2)nNH(CH3)2+ and quaternary ammonium, CH3(CH2)nN(CH3)3++MO- salts, (n=3,5,7,11).
