چکیده
BACKGROUND Cyclohexyl acetate and acetone are used as environmentally friendly solvents, while isobutene acts an intermediate in the production of methacrolein, ethers, plastics pharmaceuticals. Two La-zeolite catalysts have been studied for converting acetic acid to cyclohexyl acetate, isobutene. RESULTS La-based zeolites were synthesized from Na-nFAU by ammonium ion exchange, followed lanthanum exchange. The influence Brønsted Lewis sites on activity esterification with cyclohexanol ketonic decarboxylation was studied. Fourier transform infrared (FTIR) spectroscopy pyridine adsorption has site evaluation. presence surface leads increase selectivity, acidity favors further transformation CONCLUSION sample highest content both La Al, namely La-H-13X, showed – indication that is very important reactions. © 2021 Society Chemical Industry (SCI).

Esterification of phenyl acetic acid with p-cresol using metal cation exchanged montmorillonite nanoclay catalysts
The liquid phase esterification of phenyl acetic acid with p-cresol over different metal cation exchanged montmorillonite nanoclays yields p-cresyl phenyl acetate. Different metal cation exchanged montmorillonite nanoclays (M n+ = Al3+, Zn2+, Mn2+, Fe3+, Cu2+) were prepared and the catalytic activity was studied. The esterification reaction was conducted by varying molar ratio of the reactants,...

Methyl acetate is produced through catalytic esterification of acetic acid with methanol. Catalytic acceleration is induced by sulfuric acid or ion exchange resins respectively. Acceptable product yield is obtained by reactive distillation. Separation and isolation of methyl acetate has to overcome two azeotropes (methyl acetate – water and methyl acetate methanol). Scope of this project has be...

Two highly efficient protocols for the production of bis-coumarins under solvent-free conditions have been introduced. The reaction of 4-hydroxycoumarin (2 eq.) with arylaldehydes (1 eq.) using phthalimide-N-sulfonic acid (PhtSA) or isatin-N-sulfonic acid (IsSA), as solid-acid catalysts, afforded the mentioned compounds with good to excellent yields in short times.Briefly, we have introduced tw...
متن کاملEnzymatic Esterification of Indole-3-acetic Acid to myo-Inositol and Glucose.
Incubation of mature sweet corn kernels of Zea mays in dilute solutions of (14)C-labeled indole-3-acetic acid leads to the formation of (14)C-labeled esters of myo-inositol, glucose, and glucans. Utilizing this knowledge it was found that an enzyme preparation from immature sweet corn kernels of Zea mays catalyzed the CoA- and ATP-dependent esterification of indole-3-acetic acid to myo-inositol...
