本文报道了十二烷基磷酸二钠和一钠盐的合成,并用一种毋需测定溶液表面张力绝对值的毛细管升高法测定了每种表面活性剂水溶液的临界胶束浓度(C.M.C),此外,还对十二烷基磷酸二钠与盐酸的混合水溶液的C.M.C值也作了测定。
This paper reports the synthesis of sodium dodecyl phosphate and monosodium salt, and determines the critical micelle concentration (CMC) of each surfactant aqueous solution by a capillary rise method without the need to determine the absolute value of the solution surface tension. In addition, the CMC value of the mixed aqueous solution of sodium dodecyl phosphate and hydrochloric acid was also measured.
