Flecainide Acetate Acetic Acid Solvates [PDF]

open access: possibleJournal of Pharmaceutical Sciences, 2011
Flecainide acetate forms acetic acid solvates with 0.5 and 2 acetic acid molecules. Powder X-ray diffraction, differential thermal analysis/thermogravimetric, infrared, and potentiometric titration were used to determine the composition of solvates. Flecainide acetate hemisolvate with acetic acid decomposes to form a new crystalline form of flecainide ...

Corrosion of Brass by Acetic Acid and chlorosubstituted acetic acids

Materials and Corrosion, 1976
AbstractThe corrosion of alpha and alpha+betabrass in acetic and chlorosubstituted acetic acids is due to the capability of acetate ions to form complex compounds with copper and zinc, and by the electrochemical behaviour of redeposited copper on the brass surface.

The enols of acetic acid and methyl acetate [PDF]

open access: possibleCanadian Journal of Chemistry, 1995
We have determined the heat of formation of 1,1-dimethoxyethene, ΔHf(l) = −75.56 ± 0.87 kcal mol−1, by measuring the heat of hydrolysis. The heat of vaporization, 8.47 ± 0.10 kcal mol−1, was estimated from the boiling points at various pressures. The standard entropy of gaseous 1,1-dimethoxyethene, 82.02 ± 2.

Overview on mechanisms of acetic acid resistance in acetic acid bacteria

World Journal of Microbiology and Biotechnology, 2015
Acetic acid bacteria (AAB) are a group of gram-negative or gram-variable bacteria which possess an obligate aerobic property with oxygen as the terminal electron acceptor, meanwhile transform ethanol and sugar to corresponding aldehydes, ketones and organic acids. Since the first genus Acetobacter of AAB was established in 1898, 16 AAB genera have been

Acetic acid at 40K

Acta Crystallographica Section C Crystal Structure Communications, 1999
The redetermination of the structure of acetic acid at 40 K provides higher precision of data, reflected in s.u.'s which are about one third of those of Nahringbauer [Acta Chem. Scand. (1970), 24, 453–462].

Equilibria of copper(II) acetate with perchloric acid and lithium acetate in acetic acid

Journal of Inorganic and Nuclear Chemistry, 1972
Abstract Equilibria of the reaction of copper(II) acetate with perchloric acid and lithium acetate were investigated by spectrophotometry. The reaction of copper(II) acetate with perchloric acid is written as follows: Cu 2 ( OAc ) 4 + 2 HClO 4 ⇌ β 11 2 Cu ( OAc )( ClO 4 ) + 2 HOAc Cu 2 (

Acidities of substituted acetic acids

Journal of Molecular Structure: THEOCHEM, 1988
Abstract Experimental gas phase acidities of a series of substituted acetic XCH 2 CO 2 H, and related acids are reported. These relative acidities seem mainly determined by substituent field effects. Ab initio molecular orbital calculations for these acidities at the STO-3G and 3-21G basis levels are also discussed.

Decomposition of acetic acid monomer, acetic acid dimer, and acetic anhydride on Ni(111)

Surface Science, 1984
Abstract The decomposition of acetic acid monomer, acetic acid dimer, and acetic anhydride on Ni(111) were examined by TPD and AES. The monomer decomposed by dehydrogenation to adsorbed acetate; the acetate subsequently decomposed to CO2, H2, and adsorbed carbon and oxygen. The dimer decomposed by dehydration to adsorbed acetate, adsorbed methyl, and

Melaminium acetate acetic acid solvate monohydrate

Acta Crystallographica Section C Crystal Structure Communications, 2002
The crystals of the title new melaminium salt, 2,4,6-triamino-1,3,5-triazin-1-ium acetate acetic acid solvate monohydrate, C(3)H(7)N(6)(+).CH(3)COO(-).CH(3)COOH.H(2)O, are built up from singly protonated melaminium residues, acetate anions, and acetic acid and water molecules. The melaminium residues are interconnected by N-H...N hydrogen bonds to form
