Intercalation of trans-2-butene-1,4-bis(triphenyl phosphonium) into synthetic saponite (Sumecton SA; cation exchange capacity of 71 meq (100 g clay)-1) was conducted by the cation exchange reaction in aqueous solution. The sample was obtained as powder and thin supported film. Quantitative cation exchange was shown by the chemical composition of the product as well as the amount of the trans-2-butene-1,4- bis(triphenylphosphonium) remaining in the solution. The intercalation compound adsorbed styrene from aqueous solution and exhibited thermal stability (decomposes at higher than 400°C) as shown by the TG-DTA curves recorded in air.
