Adsorption of Trimethyl Phosphite on H-KA, H-NaA, H-CaA and H-NaX Zeolites: an IR Study
نویسنده
چکیده
Infrared spectroscopy has been used in adsorption studies of trimethyl phosphite (TMP) on the hydrogen (H) form of the A-type and 13X zeolites. Infrared spectra of H-zeolites, except H-KA, show that TMP reacts rapidly with silanol hydroxyls on their surfaces and gives rise to form product molecules such as SiOCH3 and liquid dimethyl phosphite. The unaccomplished adsorption on the HKA zeolite has been attributed to the occurence of stable KOH hydroxyls with not-exchanged K cations instead of SiOH hydroxyls on this zeolite.

FT-IR Spectroscopic Study of 1,3-Diaminopropane Adsorbed on Type A, X and Y Zeolites
Zeolites are the best known microporous molecular sieves and adsorbe molecules below a particular size in their pore structures. Therefore they are considered as heterogenous catalysts and sorbents [1]. The catalytic properties of zeolites can be understood by investigating the adsorption characteristics of reactions on their surfaces [2, 3]. During the past years the adsorption of some compoun...

In the present work, the nano-NaX zeolite and micro-NaX zeolite were synthesized via hydrothermal method. Then, the adsorption capacities and isotherms of pure gases CO2 and CH4 on the synthesized zeolite nanoparticles were determined at three temperatures of 288, 298 and 308 K and various pressures from 1 up to 20 bar. Adsorption capacities of CO2 on the nano-sized zeolites NaX were showed to ...
متن کاملInvestigation of the Use of Various Silica Source on NaX Zeolite Properties
Silicon and aluminum sources are most important reactants in the synthesis of zeolite. The use of the silicon source has an important effect on the crystallization of zeolites. Also, it can change the properties of the end product. This work reports the influence of three common commercial silica sources such as colloidal silica (Ludox AM-30), fumed silica and water glass on the crystallinity o...
