derivatives with high ligand activity," Synthetic Communications, vol.
Several experimental and theoretical studies on the adsorption of aliphatic mono- and dicarboxylic acids
on metal oxide surfaces have been reported in the literature [32-36].
Azelaic acid is naturally occurring dicarboxylic acid
(1-7 hepatanedicarboxylic acid) that has demonstrated beneficial therapeutic effects in the treatment of acne and several of hyperpigmentation including melasma and lentigomaligna.
The heavy-metal-extraction efficiency using low-molecular-weight organic acids depended on their solution concentration and number of carboxyl groups; a tricarboxylic acid (citric acid) had much more extraction capacity than a dicarboxylic acid
(oxalic acid) or a monocarboxylic acid (acetic acid).
(1938) The role of the dicarboxylic acid
The metal complexes were synthesized by the reaction of M[Cl.sub.3] * 6[H.sub.2]O (M = Sm, Nd, Tb) with 2, 2'-biquinoline-4-4'- dicarboxylic acid
dipotassium salt ([K.sub.2][[C.sub.20][H.sub.12][N.sub.2][O.sub.4]), Hydroquinone Sulfonic acid potassium salt ([C.sub.6][H.sub.5]K[O.sub.5]S), and 2-Hydroxybenzo-(alcarbazole-3-carboxylic acid sodium salt ([C.sub.17][H.sub.10]NNa[O.sub.3]) in different solvents.
Specifically, a rubber composition for coating a steel wire material is compounded with from 0.05 to 10 parts by weight of a salt compound per 100 parts by weight of a diene rubber, the salt compound including a dicarboxylic acid
derived from a natural product and an amine of a decarboxylated amino acid derived from a natural product.
Production of the phthalate-free plasticiser 1,2-Cyclohexane dicarboxylic acid
diisononyl ester is expected to begin in the second half of 2013, with an expected annual production of 40,000 metric tonnes at its facility in Marl, Germany.
Azelaic acid (nonanedioic acid), C-7 dicarboxylic acid
, is a white flake or powdered crystal with the formula (HOOC (CH2)7COOH).
Azelaic acid (AZ) is a dicarboxylic acid
found in food (whole-grain cereals and animal products).
Malic acid is a dicarboxylic acid
, meaning it has two carboxyl groups.
