THERMAL ANALYSIS -- ORGANIC DERIVATIVES -- EPOXY RESINS
Аннотация: N-Containing perfluoropentanoic acid derivatives were used as modifying additives to commercial epoxy resins. As shown by differential thermal analysis, the fluorinated organic derivatives exhibit catalytic activity in curing of epoxy resins. The following characteristics of the adhesive compounds in the cured state were determined: degree of swelling, gel fraction content, ultimate shear strength of the adhesive joint, adhesion to low-carbon St.3 steel and AMg-6 aluminum-magnesium alloy, and corrosion-protective properties with respect to these materials

POLYCHLORINATED BIPHENYLS -- SOVOL MIXTURE -- NUCLEOPHILIC SUBSTITUTION
Аннотация: In order to comprehend the data on reactivity of polychlorinated biphenyls of the Sovol mixture in nucleophilic substitution reactions we have performed quantum-chemical simulation using the RB3LYP\6-31G(d) gas phase approximation. Using the "Atoms-in-Molecules" approach, we have computed charges on the biphenyl carbon atoms adjacent to chlorine; furthermore, absolute chemical hardness and global electrophilicity index have been determined for the studied chlorobiphenyls. The calculated descriptors have been correlated with experimentally determined reactivity of the biphenyls in the hard acid-hard base nucleophilic reactions. The higher reactivity of more chlorinated substrates has been confirmed

CONGENERS -- DESCRIPTORS -- ELECTROPHILIC SUBSTITUTION
Аннотация: To explain the chemical reactivity of polychlorinated biphenyls in nucleophilic (SN) and electrophilic (SE) substitutions, quantum chemical calculations were carried out at the B3LYP/6-31G(d) level of the Density Functional Theory in gas phase. Carbon atomic charges in biphenyl structure were calculated by the Atoms-in-Molecules method. Chemical hardness and global electrophilicity index parameters were determined for congeners. A comparison of calculated descriptors and experimental data for congener reactivity in the SN and SE reactions was made. It is shown that interactions in the SN mechanism are reactions of the hard acid-hard base type, these are the most effective in case of highly chlorinated substrates. To explain the congener reactivity in the SE reactions, correct descriptors were not established. The obtained results can be used to carry out chemical transformations of the polychlorinated biphenyls in order to prepare them for microbiological destruction or preservation

Аннотация: We have suggested a one-step method for the synthesis of thi-ocarbamoyl derivatives of polyallylamine (TСPAA) and polyaminostyrene (TСPAS) in the eutectic melt thiourea/ammonium thiocyanate, that is more safe and simple in comparison with the known method of functionalization using carbon disulfide. The resulting derivatives are insoluble and can be used as sor-bents without additional cross-linking. Sorption properties of TCPAA and TCPAS toward gold, silver and mercury ions have been studied in solutions of ammonia-thiosulfate leaching of gold and silver-containing sludge of Chalgan experimental workshop, which are also contaminated with mercury. It was shown that both TCPAA and TCPAS are efficient sorbents for silver, while ef-fective recovery of gold and mercury is achieved only with low- and medium-substituted TCPAA.

Аннотация: 1,8-Bis(diisothiosemicarbazido)-3,6-dioxaoctane have been synthesized by subsequent treatment of 2,2 -(ethylenedioxy)bisethylamine with carbon disulfide, sodium chloroacetate, and hydrazine hydrate. 1,8-Bis- (diisothiosemicarbazido)-3,6-dioxaoctane has reacted with lithium 1,1-difluoropenta-2,4-dionate in glacial acetic acid to yield 1,8-bis[5R*,5 R*(5-hydroxy-5-difluoromethyl-4,5-dihydro-3-methyl-1H-pyrazol-1-yl)-1-carbothioamido]-3,6-dioxaoctane. The molecular and crystal structure of the product has been determined by X-ray diffraction analysis.

1,2,4,5-TETRAZINES -- HETEROCYCLIC LEAVING GROUPS -- TETRAZINES
Аннотация: The reactions of 3,6-disubstituted and azoloannulated 1,2,4,5-tetrazines containing heterocyclic leaving groups with S-nucleophiles were studied. The methods of introduction of functionalized thiols, including thiol derivatives of 1,7- and 1,2-dicarba-closo-dodecaboranes, into the tetrazine ring were developed. It was established for the first time that, instead of replacement of a leaving group in the tetrazine ring, the attack of S-nucleophile at the unsubstituted carbon atom occurs in the case of imidazo[1,2-b][1,2,4,5]tetrazines to form previously unknown products of nucleophilic substitution of the hydrogen atom

Аннотация: New fluorine-containing quaternary ammonium salts comprising an N-methylpiperazinyl moiety, which exhibited a high inhibiting capacity against hydrochloric acid corrosion of low-carbon steel, were synthesized. The polarization-resistance method was applied to determine the uniform corrosion rate of steel-3 in relation to the structure and concentration of the fluorine-containing substituents in the salts. It was found that the structure of the fluorine-containing moiety of the quaternary ammonium salts does not significantly influence the corrosion processes
