Salts of the oligomeric propoxy derivatives of amines (nonylamine, dodecylamine, hexadecylamine and propylene oxide) with ethylene chlorohydrin were synthesized in two steps. The degrees of oligomerization of the amines are calculated as 4.4 for epoxy derivative of nonylamine, 5.8 for epoxy derivative of dodecylamine and 3.8 for epoxy derivative of hexcadecylamine. In the second step, propoxy derivative of the alkylamine reacted with ethylene chlorohydrin. Structure and composition of the salts were confirmed by using IR spectroscopy and provided with within article. Surface tension and electroconductivity properties of the surfactants were examined at room temperature. Isotherms (surface tension and electroconductivity) of the salts were plotted with respect to concentration. Corresponding main surfactivity (CMC, gamma(CMC), pi(CMC), C-20, pC(20), Gamma(max), A(min)), electroconductivity (alpha and beta) and thermodynamic (Delta G(mic) and Delta G(ad)) parameters of the salts were calculated. Critical micelle concentrations of the salts were found out as 5.23*10(-4) mol/l for nonylamine, 4.15*10(-4) mol/l for dodecylamine and 1.38*10(-4) mol/l for hexadecylamine derivatives. Moreover, petrocollecting properties of these salts were examined with respect to time and maximum values of petrocollecting coefficients were calculated. All salts demonstrated good petrocollecting coefficients with minimum value 19.20 and maximum value 36.80. Duration of petrocollecting abilitity is determined as 7 and 8 days
