Volume : III, Issue : IV, May - 2013 FTIR SPECTRA OF ADSORBED PYRIDINE OVER HIGH SILICA USY ,TI-USY AND FE-TI-USY ZEOLITE AND ALKYLATION OF O-TOLUIDINE OVER THEM. K.U.GORE Published By : Laxmi Book Publication Abstract : Alkylated aromatic amines are industrially very important. Ortho alkylated
amines are used as intermedites for producing dyes , insecticides, resins ,
Stabilizers,rubber processing chemicals and as a liquid fuel in missiles. The usefulness
of the zeolite due to its modified stural changes can be tested by studing the change in
its role as a catylist in carrying out the chemical reactions as compared to its original
sample. zeolite- Y due to its 3D pore structure is the single largest Zeolite used in
different industries even today. zeolites are stabilized at higher temperature and in
hydrothermal condition to increase its stability and usefulness under various reaction
conditions. The synthesized zeolite is modified and made ultra-stable. The Synthesized
Na-Y zeolite is obtained in pure and highly crystalline form as a original sample. It was
ion exchanged to convert into NH4-Y form by reflux method by using Ammonium Nitrate
solution then filtered and washed with deionized hot water several times to remove any
traces of NO3,then the sample is dried and calcined at 5000C,The process are repeated
three times to convert it in to highly crystalline low silica H-Y zeolite. The sample H-Y
zeolite prepared is used for stabilization by treating carefully under controlled
hydrothermal conditions at 550OC for 4h and then gradually cooling at the rate of
2oC/min. finally ion exchanged to obtain the product. as per above procedure of
exchange. By using this as a mother sample, It was further treated carefully under
controlled hydrothermal conditions at 700OC for 4h and finally at 850 OC for 4h and
repeating the above procedure for every sample at each temperature in succession
carefully, one after the other, to obtain the final product-USY-550-700- 850. This high
silica H-USY-550-700-850 sample was used for encapsulation of Ti and Fe in the
zeollites and are modified to Ti-USY and Fe-Ti USY productsby using Ti and Fe sources
respectively. These samples are,. used for FTIR Spectra of adsorbed pyridine to study
the type of acidity produced on the sample prepared and are finally used for the reaction
study of Alkylation of O-toludine by methanol at different temperatures all these
samples prepared are used for alkylation of methanol. Keywords : Article : Cite This Article : K.U.GORE, (2013).
