Abstract: The intercalation reaction between aluminum dihydrogen tripolyphosphate(ATP) and organic amine such as methylamine, ethylamine, propylamine and butylamine were characterized by infrared, X-ray diffraction, scanning electron microscopy, energy disperses spectroscopy as well as gravitational thermal analysis and titration experiment. The results show that the organic amine is intercalated into the interlayer of ATP. The interlayer spacing of ATP is extended from 0.795 nm to 1.71 nm by intercalation of organic amine. The interlayer spacing of the intercalation compound is linear to the carbon number(Cn) of organic amine with d=0.229Cn+0.811 and R2=0.9986. Long molecule chains result in stripping tendency of the intercalation compounds. The acidity and thermal decomposition temperature of ATP are also changed after the intercalation of organic amine, but all layered particle morphologies are similar.
