Correlation of vapor-liquid equilibrium data for acetic acid-isopropanol-water-isopropyl acetate mixtures
(Brazilian Society of Chemical Engineering, 2006-12)
A correlation procedure for the prediction of vapor - liquid equilibrium of acetic acid-isopropanol-water-isopropyl acetate mixtures has been developed. It is based on the NRTL model for predicting liquidactivity coefficients, ...
An Improved Procedure for the Preparation of [Bis(2,2,2-trifluoroethyl)phosphono]acetic Acid
(GEORG THIEME VERLAG KG, 2010)
A different and improved procedure for the preparation of [bis(2,2,2-trifluoroethyl)phosphono]acetic acid in just one step from bis(2,2,2-trifluoroethyl)phosphonate is described. The protocol employs a Michaelis-Becker ...
Synthesis of acetal (1,1-diethoxyethane) from ethanol and acetaldehyde over acidic catalysts
(Elsevier Science, 2000-04)
Various acidic catalysts (zeolitic and amorphous FCC catalysts, mordenite, montmorillonite, and sulfonic ion exchange resin) were tested for the synthesis of acetal from ethanol and acetaldehyde, at 4 and 20C and atmospheric ...
Liquid-liquid equilibrium data and thermophysical properties for ternary systems composed of water, acetic acid and different solvents
(2019-03-01)
Liquid-liquid equilibrium (LLE) data for water + acetic acid + {1-butanol or isopentanol or methyl-terc-butyl ether (MTBE) or methyl isobutyl ketone (MIBK) or diisobutyl ketone (DIBK) or isoamyl propionate} systems at T = ...
Performance and Economic Viability of Broiler Chickens Fed with Probiotic and Organic Acids in an Attempt to Replace Growth-Promoting Antibiotics
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2019-01-01)
The aim of this study was to evaluate diets supplemented with probiotic (Bacillus amyloliquefaciens) and organic acids (lactic, acetic and butyric acid) in attempt to replace the antibiotics and anticoccidial (avilamycin ...
Production and characterization of physalis vinegar

Atmospheric oxidation of vinyl and allyl acetate: Product distribution and mechanisms of the OH-initiated degradation in the presence and absence of NOx
(American Chemical Society, 2012-08)
The products formed from the reactions of OH radicals with vinyl acetate and allyl acetate have been studied in a 1080 L quartz-glass chamber in the presence and absence of NOx using in situ FTIR spectroscopy to monitor ...
