Abstract: Cation exchange of dimethyldioctadecylammonium (DMDO) ion for dimethylbenzyllauryl-ammonium (DMBL) ion previously reacted with centrifuged homoionic Na+ bentonite has been demonstrated. The amount of DMBL ion removed from the clay was determined by ultraviolet spectroscopy.

In order to shift the exchange equilibrium toward removal of the DMBL cation, a large excess of DMDO cation was required. At the limit of these experiments, it was found that 16 percent of the DMBL cation was exchanged.
