This is due to the presence of salt of carboxylic acid
and carboxylates are mainly responsible for this chelation in large number of mono and multidentate ligands.
At a concentration of 0.5% w/w of IA, the final pH was 4.0 (latex IA-1), and the concentration of carboxylic acid
buried in the latex particles was less when compared with the fraction of carboxylic groups for the other latexes.
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.
from Oxea are used in the production of synthetic lubricants and as building blocks for the animal feed industry.

Flory (3, 4), considering data for relatively high conversion to avoid large changes in polarity during the reaction, found that ethylene glycol-succinic acid polyesterification is predominately a trimolecular process with a partial order of two with respect to carboxylic acid
and one with respect to alcohol.
* US Patent 8,921,295 B2; American Sterilizer Company, Mentor, OH, has patented a concentrated neutral detergent composition that is comprised of one or more nonionic surfactants, comprising a primary or a secondary alcohol ethoxylate, an alcohol alkoxylate other than said ethoxylate, an aromatic ethoxylate, a modified ethoxylate, or a block polymer of propylene oxide and ethylene oxide, or any combination thereof; one or more hydrotropes comprising an amine oxide, or a glucoside, or both; one or more chelants; a buffer comprising one or more alcohol amines, or one or more organic acids, or any combination thereof; one or more corrosion inhibitors comprising an amine, amidazole, diazole, triazole, carboxylic acid
, or any combination thereof; and water.
Fabrication of HPC-mefenamic acid conjugates was achieved by using p-toluenesulfonyl chloride as carboxylic acid
(a functional group in drug) activator at 80C for 24 h under nitrogen atmosphere.
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.
The topics include chiral non-racemic isocyanides, Ugi and Passerine reactions with carboxylic acid
surrogates, multiple multi-component reactions with isocyanides, the synthesis of pyrroles and their derivatives from isocyanides, and carbene complexes derived from metal-bound isocyanides.
The researchers used a small electrical voltage to help deposit a conducting polymer film of poly(3,4-ethylenedioxythiophene) (PEDOT) bearing carboxylic acid
groups on to a 2-centimeter-square glass base (Fig.
Key statement: A rubber composition having an excellent adhesion with a brass-plated wire and an excellent heat aging resistance of a vulcanite containing (A) 100 parts by weight of a diene-based rubber, (B) 0.1 to 10 parts by weight of, as a vulcanization accelerator, an amine salt compound of a carboxylic acid
group-containing disulfide having the formula (I):
Given the broadened nature of the subject, they have reorganized the material on the basis of functional groups and offer 12 chapters that parallel most classical organic chemistry textbooks in their coverage of alkanes, alkenes, alkynes, alcohols and ethers, organic halides, aromatics, aldehydes and ketones, carboxylic acid
and derivatives, conjugated carbonyl compounds, amines, and pericyclic reactions.
Antihypertensive activity of N-(Mercaptoacyl)- thiazolidine carboxylic acid
has already been reported.
