“…Despite several studies on this useful reaction, the work on high molar ratio is quite limited; as with the high molar ratio rate of reaction increases and reaction time also decreases. There are a number of studies related to the other esterification reactions catalyzed by ion exchange resins [25][26][27][28][29][30][31][32][33][34] …”

Esters are an important pharmaceutical intermediates and very useful perfumery agents. In this study the esterification of acetic acid with n-butanol and iso-butanol over an acidic cation exchange resin, Amberlyst 15 were carried out. The effects of certain parameters such as temperature, catalyst loading, initial molar ratio between reactants on the rate of reaction were studied. The experiments were conducted in a stirred batch reactor in the temperature range of 351.15 K to 366.15K.Variation of parameters on rate of reaction demonstrated that the reaction was intrinsically controlled.The activation energy for the esterification of acetic acid with n-butanol and iso butanol is found to be 28.45 k J/mol and 23.29 kJ/mol respectively. ©2011 BCREC UNDIP.

“…Furthermore, high yield in case DEM, compared to DOP and DBP is probably due to less steric hindrance felt by incoming ethanol from monoethyl malonate formed in the first step. DOP formation has been catalyzed by zeolites (23), metallic oxides (25), solid super acids (26,27), and heteropoly acids (27,28). Suter (29) has reported a non-catalytic process for the manufacture of DOP, at very high temperatures, at which autocatalysis occurs.…”

Amorphous zirconium titanium phosphate (ZTPA), an advanced inorganic ion exchanger of the class of tetravalent bimetallic acid (TBMA) salt, has been synthesized by sol gel route. ZTPA has been characterized by inductively coupled plasma atomic emission spectrometer (ICP-AES), Thermal analysis, Fourier transform infrared spectrometer (FTIR), and X-ray diffraction (XRD). The acid sites present in ZTPA indicate good potential to be explored as solid acid catalyst. The catalytic characteristics of ZTPA have been evaluated by determining surface area and surface acidity. The catalytic performance of ZTPA as a solid acid catalyst has been explored by studying esterification as a model reaction wherein mono and diesters have been synthesized. Crystalline zirconium titanium phosphate as well as amorphous and crystalline phases of zirconium phosphate and titanium phosphate have also been synthesized, characterized, and their catalytic performance investigated for comparative studies. TBMA salt exhibits enhanced catalytic activity compared to its single salt counterparts and amorphous phases exhibit higher catalytic activity compared to their crystalline phases.

“…Some important features of this polyanion are: stability in the pH range from 0 to 12, thermal stability, rendering high temperature reactions possible, and easy recovery of both pure and supported catalysts. 17 In continuation of our research on the syntheses and application of heteropolyacids in organic syntheses, [17][18][19][20][21][22] and due to the importance of derivatives of benzoic acid in medicine and industry, we hereby report the applicability of Preyssler's anion for efficient oxidation of aromatic aldehydes to the corresponding carboxylic acids. The major aim of the work described herein "is the design and development of applications for Preyssler's catalyst".…”

]) were used and had their activity compared with those of some Keggin structures. Our data indicate that Sodium30-tungsto pentaphosphate, the so-called Preyssler's anion, with high hydrolytic (pH=0-12) and thermal stability is the best catalyst with high yield and good selectivity. Under microwave irradiation, this polyanion supported on SiO 2 was found to be an excellent catalyst for aldehydes with low loss factor in 1-2 min (the loss factor is a measure of the ability of the material to dissipate energy). The effects of various parameters, including catalyst type, nature of the substituent in the aldehyde and temperature, on the yield of the carboxylic acids were studied.
