Chemical Synthesis Lab Report
. Ecologically safe methods for the synthesis of five membered and six membered cyclic carbonates
by the reaction of transesterification of dialkyl carbonates with dihydric alcohols will be developed. 2.
Methods will be developed for the preparation of 2 hydroxyethyl, 2 and 3 hydroxypropyl, 3
hydroxybutyl derivatives of a number of alcohols, thiosparts, carboxylic acids, amides, sulfonamides,
amines, heterocyclic compounds. 3. New coordination compounds Zn (II), Cu (II), Ni (II), Co (II), Fe
(III), Mn (II), Cd (II), Pd (II), La (III ), Sn (II), Sn (IV), Zr (IV), Y (III), Hf (IV) on the basis of
synthesized 2 hydroxyethyl, 2 and 3 hydroxypropyl, 3 hydroxybutyl derivatives, their structure by X
ray diffraction analysis ; The catalytic activity ... Show more content on Helpwriting.net ...
The catalytic activity of Zn (II), Cu (II), Ni (II), Co (II), Fe (III), Mn (II), Cd (II), Pd (II), La ( III), Sn
(II), Sn (IV), Zr (IV), Y (III), Hf (IV) on the basis of synthesized 2 hydroxyethyl, 2 and 3
hydroxypropyl, 3 hydroxybutyl derivatives in cyclic complex polymerization reactions Ethers (lactide,
ε caprolactone, trimethylene carbonate), as well as curing epoxy resins. The polymerization kinetics,
monomer conversion, molecular weight and molecular weight distribution of polymers obtained in the
presence of synthesized complexes and in the presence of well known polymerization initiators (tin
(II), (IV) crystal hydrates, stannous octanoate) have been compared. The patterns of the influence of
the structure and composition of the coordination environment, as well as the nature of the metal
center on the activity of complex compounds as initiators of polymerization, are revealed. 2019 1.
Methods will be developed for the polymerization of the resulting lactones, thio and aminolactones in
solution and monomer weight, the conversion of monomers during the polymerization reaction, the
average and weight average molecular weights of the polymers, and the molecular weight distribution
are determined. 2. Tensile strength, elongation at break, Young s modulus, in vitro and in vivo
destruction rate (linear mice), changes in physicomechanical characteristics, degree of crystallinity,
molecular weight in the course of destruction, and Also the dynamics of the tissue reaction for samples
of polymer products (films, veins, fibers) based on synthesized
