Synthesis of Di-Propargyl Esters of Dicarboxylic Acids
With FTIR, they determined that the protective film consists of a complex of the dicarboxylic acid
with [Zn.sup.2+] ions and Zn[(OH).sub.2].
The formation constants of the complexes were determined by titrating solution mixtures of [[Pd(MME)([H.sub.2][O.sub.2])].sup.2+] (1 mmole) and the ligand in the concentration ratio of 1 : 1 for amino acids, peptides, and dicarboxylic acids
. The titrated solution mixtures each had a volume of 40 mL and the titrations were carried out at 25[degrees]C and 0.1 M ionic strength (adjusted with NaN[O.sub.3]), such a condition is similar to what exists in biological system.

in diabetes or starvation.
Fomina and her co-workers have shown more than 50 years ago already that the mixture containing dicarboxylic acids
from the amber acid ([C.sub.4]) to the sebacic one ([C.sub.10]) can be separated successfully yielding high-grade individual acids.
The copolyester consists of repeat units of one or more aliphatic dicarboxylic acids
, one or more aromatic dicarboxylic acids
selected from the group consisting of terephthaliic acid, isophthalic acid and phthalic acid, and a stoichiometric amount of a glycol component consisting of one or more glycols selected from the group consisting of aliphatic glycols and cycloaliphatic glycols.
Polyamides consist of copolymers of dicarboxylic acids
and diamines, held together by amide links.

These include terpenoids, aliphatic aldehydes, phthalates, phenol, mono- and dicarboxylic acids
, diisocyanates, and various photoinitiators (Salthammer et al.
