Kinetics of oxidation of phenyl acetic acid and DLMandelic acid by potassium permanganate in aqueous acetic acid and perchloric acid mixture reveals that the kinetic orders are first order in oxidant, first order in H+ and zero order in substrate for phenyl acetic acid. DL-Mandelic acid exhibits first order in oxidant and zero order in substrate. The results are rationalised by a mechanism invo...

in this work, the effects of acetic and lactic acids addition to rice during cooking, on the texture and morphological properties, and too, the gelatinization temperature (gt) of the cooked domsiyah rice was investigated. all experiments were carried out in triplicate and data analyzed in randomized completely by spss15 software. the results showed that acid addition to rice during cooking caus...

Acetic acid is one of the major inhibitors of spent sulfite liquor (SSL) fermentation for ethanol production. The objective of this study was to remove acetic acid from hardwood SSL using anion exchange resin in order to achieve effective fermentation with Pichia stipitis CBS6054. Lignosulfonate, as well as sulfate and sulfite ions in the SSL hindered the removal of acetic acid by anion exchang...

The degree of Shigella flexneri inhibition by acetic acid in a chemically defined medium was dependent upon the concentration of undissociated acetic acid in the medium. Under the conditions of the experiments, the critical concentration of undissociated acetic acid that completely inhibited S. flexneri multiplication was approximately 0.0018 M. Adjustment of the medium from pH 6.0 to 7.0 after...

exergy analysis and response surface methodology (rsm) is applied to reduce the exergy loss and improve energy and exergy efficiency of acetic acid production plant. exergy analysis is run as a thermodynamic tool to assess exergy loss in reactor and towers of acetic acid production process. the process is simulated in aspen plus(v.8.4) simulator and the necessary thermodynamics data for calcula...

This review focuses on acetic acid bacteria in the winemaking process. The enumeration, isolation and identification of acetic acid bacteria from grapes and wines are discussed. This is followed by an outline of the conditions and measures that can assist the wine producer to inhibit the unwanted growth of acetic acid bacteria in wine, which include the ethanol concentration, low pH, minimum ox...

The treatment of cholera by acetic acid, suggested by Dr. Greene in the September number of the Indian Medical Gazette, deserves, I think, to be put to the test by the profession. When I perused Dr. Greene's article, it struck me that, from its strong antiseptic property, acetic acid may do good by counteracting the morbific influence of the cholera miasm in the blood. Besides, being a stimulan...

IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND (SYSTEMATIC NAME: 5H-dibenzo[a,d]cyclo-hepta-triene-5-carboxamide ethanoic acid solvate), C(16)H(13)NO·C(2)H(4)O(2), the cytenamide and solvent mol-ecules form a hydrogen-bonded R(2) (2)(8) dimer motif, which is further connected to form a centrosymmetric double ring motif arrangement. The cycloheptene ring adopts a boat conformation and the dihedr...

The title compound, C(9)H(8)O(2)S(2), can be used as a chain transfer agent and may be used to control the behavior of polymerization reactions. O-H⋯O hydrogen bonds of moderate character link the mol-ecules into dimers. In the crystal, the dimers are linked into sheets by C-H⋯O inter-actions, forming R(4) (2)(12) and R(2) (2)(8) edge-fused rings running parallel to [101]. There are no inter-mo...

Chloroplasts, Compartmental Analysis, Indole-3-acetic Acid (LAA), Spinach Mesophyll Cells, Tryptophan Uptake Using [14C]tryptophan as a precursor, the intracellular localization o f indole-3-acetic acid biosynthesis in spinach mesophyll cells was investigated. Chloroplasts as well as extraplastidic compartments were able to transform tryptophan into indole-3-acetic acid. The cofactor requiremen...
