Esterification of malic acid on various catalysts

Recent Developments on the Mechanism and Kinetics of Esterification Reaction Promoted by Various Catalysts

Bulky diarylammonium arenesulfonates as selective esterification catalysts.

More environmentally benign alternatives to current chemical processes, especially large-scale, fundamental reactions such as ester condensations, are highly desirable for many reactions. Bulky diarylammonium pentafluorobenzenesulfonates and tosylates serve as extremely active dehydration catalysts for the ester condensation reaction of carboxylic acids with equimolar amounts of sterically dema...

Malic Acid & Metabolic Acidosis

Label-MMAcid-Rev030410 BACKGROUND Ruminants are animals that have multiple stomachs to allow consumption and digestion of fibrous feedstuffs. Key to this digestive process is the bacterial breakdown of the fiber in the first stomach or rumen. The bacterial balance in the rumen can shift, allowing the ruminant to adapt to different diets. Ruminal bacteria convert fiber into lactate and volatile ...

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,...
