Cetylmethylammonium bromide

Cetylmethylammonium (CTMA) as the clay exchange cation and decylamine as the co-surfactant were used to form a PCH. A 1.0 wt % suspension of previously prepared saponite was allowed to react at 50°C with a 0.3 M aqueous cetylmethylammonium bromide solution in two fold excess of the clay cation exchange capacity. After a reaction time of 24h, the product was washed with ethanol and water to remove excess surfactant and...
