AN IR STUDY OF TRIMETHYL PHOSPHITE ADSORBED ON NaY ZEOLITE

ABSTRACT

Infrared spectroscopy has been used to investigate the adsorption of trimethyl phosphite (TMP) on the NaY zeolite. The obtained spectrum indicates that at room temperature TMP reacts rapidly with the non-acidic (silanol) hydroxyls on the surface of the zeolite to give SiOCH₃ as a chemisorbed product and liquid dimethyl phosphite (DMP).
