The patent, entitled "Benzoic acid, benzoic acid derivatives and heteroaryl carboxylic
acid conjugates of hydromorphone, prodrugs, methods of making and use thereof.
Like 1 and 3% of the samples the 5% have no carboxylic
group which means having no amino acid.
We achieved this reduction by adding organic carboxylic
acid to chelate the dissolved metal ions.
acids are building blocks of utmost importance in our chemical industry, as these motifs are extensively used in the manufacture of soaps, detergents, pharmaceuticals, rubber, plastics, dyes, textile, perfumes, and animal feed, among many others.
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
acids are used in various industries for the production of polymers, pharmaceuticals, solvents, and food additives.
9 wt% ethylenically unsaturated carboxylic
acids, such as vinyl esters of carboxylic
BASF has obtained a patent for a n aqueous coating formulation comprised of a substituted, branched polyethyleneimine, which is obtained by a process comprised of reacting a branched polyethyleneimine having a weight-average molecular weight of from 500 to 10,000 g/mol with a carboxylic
acid derivative of formula (I) R--(C=0)X (I), wherein R is a C5 to C18 alkyl group or a C5 to C18 alkenyl group, X is a halogen, a hydroxyl group, or a group R--(C=0)--O--, a molar amount of the carboxylic
acid derivative in the reacting is from 3 to 10 mol percent of a molar amount of ethyleneimine employed in preparing the branched polyethyleneimine, the reacting is comprised of formation and removal of a byproduct HX, and the formulation is configured to coat a substrate that is comprised of tannin.
This diluted standard is DEA-exempt, so there's no need to purchase costly neat materials or make your own standards, and it is prepared in acetonitrile, which helps maintain stability by preventing methylation of the carboxylic
acid group on the molecule.
Then, gold nanoparticles were coated by an insulating molecule layer (mercapto alkyl ended to carboxylic
acid) through self-arrangement method.
A particulate superabsorbent polymer composition comprising a superabsor-bent polymer comprising: a) at least one monomer selected from an ethylenically unsaturated carboxylic
acid; ethylenically unsaturated carboxylic
acid anhydride; salts or derivatives thereof based on the super-absorbent polymer; b) from about 0.
US Patent No.: 8,647,317 B2 Superabsorbent polymer having a capacity increase: Gonglu Tian, Greens-boro, NC, US; David L. Bergman, Jr., Greensboro, NC, US; and Yaru Shi, Greensboro, NC, US. Assigned to Evonik Stockhausen, LLC, Greensboro, NC, US
