Activation of the Carboxylic Acids by Anhydride Formation with N-Acyl-N-Alkyl Carbamic Acid
The mixed anhydrides with N-acyl carbamic acid (IV) were prepared by the reaction of carboxylic acids (Ill) with N-chlorocarbonyl lactams (Ila) or sec. amides (lib). Decarboxylation of IV yielded N-acyl lactams (VI), while symmetrical anhydrides (VII) were obtained by the side reaction of IV with carboxylic acids (III). Aminolysis of IV yielded carboxylic acid amides (IX) in high yield and puri...
متن کاملFormation Constants and Partial Formation Constants of Some Metal Ions Coordinated with 8–Hydroxyquinoline by Potentiometric Titration
The association equilibria of HQ and HQ–coordinated with some transition metal cations such as: Al(III), Ca(II), Cd(II), Co(II), Cu(II), Fe(III), Mg(II), Ni(II), Pb(II) and Zn(II) ions were studied using potentiometric technique. The association constant (Ka) of HQ was calculated from the average number of protons attached per repeating unit in the HQ (nA) at different pH values. This value of ...
متن کاملGAS-PHASE ACIDITY OF SOME CARBOXYLIC ACIDS CALCULATED BY MNDO
Gas-phase acidities of 15 aliphatic carboxylic acids, X CH -,COOH, have been calculated using the MNDO method. Among the substituted groups exist the electron donor alkyl groups and electron acceptor halogens. The average error in acidity is within the experimental uncertainty of the data. Systematic errors have been found for the substituents which form internal hydrogen bondings. A reaso...
متن کاملsurface roughness of linear chain carboxylic acid anhydride modified wood
this study was carried out to investigate the effect of esterification on the surface roughness of eastern cottonwood. eastern cottonwood was modified without using any catalyst and solvent at different temperatures and times with two linear chain carboxylic acid anhydrides (acetic anhydride or propionic anhydride). different weight percentage gains (wpgs) were obtained at different conditions....
متن کاملA Student-Designed Potentiometric Titration: Quantitative Determination of Iron(II) by Caro's Acid Titration
Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...
