Abstract: Clay-organic complexes of the clay minerals sodium hectorite and sodium montmorillonite with the hydrochlorides of guanidine, amino-guanidine, methylguanidine, and triaminoguanidine were examined for thermal stability by the oscillating-heating x-ray technique. Completely exchanged complexes increase the thermal stability of these two clays by as much as 275°C.

Infrared analyses were also made on these same clay-organic complexes. There is a marked difference between the infrared patterns of the clay-organic complexes and the patterns of the clays or the organic salts alone. More experimental work must be done before it will be possible to interpret completely the clay-organic infrared patterns.
