Pyrolysis of Metal Salts of Carboxylic Acids.

Antimicrobial activity of some higher amine salts of carboxylic acids.

Various higher amine salts of dicarboxylic and tricarboxylic acids were prepared and tested for antimicrobial activity in vitro. Although activity was present in all compounds tested, tetradecylammonium malonate showed the greatest activity with the widest spectrum. This compound was effective against gram-negative as well as gram-positive microorganisms, yeast, and fungi.A high order of microb...

Transition Metal-Catalyzed Decarboxylative Coupling Reactions of Alkynyl Carboxylic Acids

The decarboxylative couplings of alkynyl carboxylic acids are an attractive area of research in organic chemistry, because the structure of aryl alkyne is one of the important building blocks for the synthesis of p-conjugated compounds. The use of alkynyl carboxylic acid as an alkyne source has several advantages in handling and storage. As a catalyst, palladium, copper, nickel, and silver were...

Fe3O4@ZrO2-SO3H Nano-particles for esterification of carboxylic acids

In this work preparation of sulfonic acid functionalized magnetite encapsulated zirconia (Fe3O4@ZrO2-SO3H) has been reported. Structural, chemical, and magnetic properties of the magnetically supported catalyst have also been investigated by Fourier transform infrared (FT-IR) spectroscopy, wide angle X-ray diffraction spectroscopy (WXRD), thermal gravimetric analysis (TGA), energy dispersive X-...

Determination of Carboxylic Acids in Apple Juice by RP HPLC

Low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. It was thought that the HPLC is the best method of the determination of organic acids in the apple juice. In this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for ...
