PREPARATION OF FORMIC ACIDPURPOSE:Formic acid is safely prepared in high yield from inexpensive raw materials by the liquid-phase oxidation of formaldehyde with peracetic acid under atmospheric pressure at comparatively low temperature.YASUDA KIYOSHIGOTOU YUKIHISA...
Formic acid-free N-alkyl-N'-methyl-alkylene ureas (I) are obtained from reaction mixtures obtained from the corresponding alkylene urea (II) and formaldehyde in presence of formic acid by supplying the mixture to the upper part of a distillation column, carrying out distillation under specific pr...
The formation of formic acid was then determined by the sodium hydroxide titration. The remaining reaction product was dialyzed against distilled water for 72 h, concentrated by the vacuum evaporation method at 50 °C mixture and was reduced dialyzed bayga7i0n mst gdiNstailHleBd4wfoarte2...
formate is reacted with water and a basic compound havinga pK[err] of the conjugate acid of the corresponding dissociationstate of [err] 3 measured at 25[err]C in aqueous solution, the methanol formed is separated off and, optionally, the desired acid contentis set by adding formic acid....
Mono-percarboxylic acids are prepared by reacting hydrogen peroxide with the anhydride of a dicarboxylic acid in the presence of a liquid which is miscible with hydrogen peroxide and which has a dielectric constant greater than 20, provided that said liquid does not comprise solely water or ...
PURPOSE:To prepare a high quality acetic acid, in high yield, suppressing the by- production of carbon dioxide and formic acid, by oxidizing acetaldehyde with molecular oxygen in the presence of a catalyst comprising manganese acetate and cerium acetate or further copper acetate at specific ratios...
