Where salts of the amines, phenol and carboxylic acids
are reportedly antimicrobial [22, 23].
In the previous chapter, adding the proper amount of organic carboxylic acid
improves the corrosion resistance after heating.
The carboxylic acids
used were propionic, butyric, valeric and benzoic acids.
Residual carboxylic acid
concentrations in the supernatant were determined using high pressure liquid chromatography (HPLC).
Ti(IV) Catalyzed Conversion of Primary Carboxamides to Carboxylic Acids
2-pyrazine carboxylic acid
, 5-methyl-2-pyrazine carboxylic acid
and 2, 3-pyrazine dicarboxylic acid in 1:1 and 1:2 molar ratio in anhydrous THF in the presence of triethylamine at room temperature may be represented by the following general equations:
Even though many of the 22 POE oils tested had initially high water or carboxylic acid
contents and the majority of the compressor tests were terminated due to severe oil discoloration observed in the sight glass, no copper plating was observed.
We have tried to determine if either the presence of new carboxylic acid
end groups or the corresponding molecular weight variations are responsible for the observed effects on the polybutylene terephthalate crystallization kinetics.
Eastman Chemical Company today announced an expansion of carboxylic acids
capacity at its Longview, Texas, and Kingsport, Tennessee, facilities.
The carboxylic acid
distributed in the aqueous phase has a strong influence on the wet scrub resistance and on the characteristics of the final products.
It has been reported earlier that this leads to the formation of carboxylic acid
groups on the surface, thus making it more hydrophilie.
He includes special cases such as ionic liquids and the formation of chiral aggregates from achiral building blocks and experimental strategies and reagents researchers can use as he describes aryl-containing carboxylic acids
and other carboxylic acid
-based reagents; hydroxyl- and thiol-containing reagents; amine-based reagents; organic-based chiral derivatizing and solvating agents; reagents incorporating phosphorus, selenium, boron and silicone atoms; host compounds as chiral NMR discriminating agents; chiral discrimination with metal-based reagents; and chiral NMR discrimination with highly ordered systems.
