carboxylic acid

Carboxylic acid and phosphate ester derivatives of fluconazole: synthesis and antifungal activities.

Roughly the first half covers basic aliphatic and aromatic hydrocarbons, halogenated derivatives, and alcohol, ether, thiol, and amine groups; the second half delves into more complex reactions involving aldehydes, ketones, carboxylic acid derivatives, polymerization, and larger biomolecules.

If it is considered that at pH 7.5 most of the carboxylic acid had been ionized, the absorption bands [[upsilon].sub.a]([COO.sup.-]) and [[upsilon].sub.s]([COO.sup.-]) for HA are identified as uncomplexed (Table 2) where Cr-HA is referred to as a chromium-humic acid complex.

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.

Crystallization kinetics of pure PBT and PBT blended with an epoxide, which was used to reduce the free carboxylic acid concentration, were compared.

In high-temperature blending or extrusion compounding, the maleic anhydride in the 4700 grade reacts with the free amine of nylon, while the glycidyl methacrylate epoxy group of the 8660 grade reacts with the free carboxylic acid groups of polyester.

Oxea is moving forward in studying the feasibility of a new world-scale production plant for the manufacturing of carboxylic acids. At the same time, the company is also implementing measures to further improve and debottleneck its manufacturing processes at its existing carboxylic acid production units.

9,168,218 B2; L'Oreal has patented a composition that contains photoluminescent polymer (PLP), which is a polyester synthesized from a multifunctional monomer containing two carboxylic acid groups and a functional moiety comprising a carboxylic acid group or a hydroxyl group, and a diol.

The mercapto moieties of said dimercaptothiadiazole are desirably protected from prematurely reacting with, for example, diene-based elastomers and sulfur-containing silica coupling agents by pre-reaction with an aromatic carboxylic acid chloride or by reacting in situ with an aromatic carboxylic acid.

6-Hydroxy-1,2,3,4-tetrahydro-AY-carboline-3- carboxylic acid (3)

Two special primers explain reaction mechanisms and carboxylic acid derivative reaction mechanisms.
