Synthesis and CMC determination of a series of aliphatic diamines.
Fifteen aliphatic diamines substituted with one long alkyl chain (C10-C18), a varying number of methylene groups separating the nitrogens (two to six), and various aliphatic substituents were synthesized and their CMC's were determined. While the length of the long alkyl chain plays a dominant role in influencing the CMC, the other N-alkyl substituents as well as the length of the methylene chain separating the two nitrogens of the diamine are significant factors.
