ResumoThe micellar molecular weights of four normal paraffin chain salts in dilute aqueous solution have been revised to give the values: dodecyltrimethylammonium bromide, 12200; sodium decyl sulfate, 9300; sodium dodecanesulfonate, 12300; sodium dodecyl sulfate, 11500. A reference model of a spherical micelle has been proposed. The MMW's estimated with its use show substantial agreement with the experimental values, except for C12 salts. The MMW's of spherical micelles of C16 salts have been predicted and verified experimentally. The data on alkyl pyridinium bromides indicate that the radius of the sperical micelle is equal to the alkyl chain length.
