Dodecanol Dodecyl bromide

A linear behavior between k and n was found for n-alkylbenzenes eluted with pure micellar eluents of the anionic sodium dodecyl sulfate (SDS), cationic cetyltrimethylammonium bromide (CTAB), and nonionic poly[oxyethylene(10 or 23)]dodecanol (Brij 22 or Brij 35), and with hybrid eluents containing SDS or CTAB and 2-propanol. The homologues of n-alkylphenones eluted with pure and hybrid mobile phases of CTAB showed the same behavior, but linear relationships were observed between log k and nc for these compounds eluted with SDS mobile phases, the same type of correlation found in aqueous-organic systems. It seems that the... 

Surprisingly, almost all the applied work in MLC to date appears to have involved only ionic micellar mobile phases composed of either anionic sodium dodecyl sulfate (SDS), or cationic hexadecyltrimethyl-ammonium bromide or chloride (CTAB or CTAC), and dodecyltrimethyl-ammonium bromide (DTAB). Reports on the use of unclmrg nonionic surfactants, such as Neodol 91-6 and polyoxyethylene(23) dodecanol (Brij 35) are exceptions.
