Документ Features of Interaction in the Sulfur(IV) Oxide–Hexamethylenetetramine–Water System: A First Example of Identification of the Product with a Sulfur–Carbon Bond(2011) Khoma, Ruslan E.; Shestaka, A. A.; Shishkin, O. V.; Baumer, Vyacheslav N.; Brusilovskii, Yu. E.; Koroeva, L. V.; Ennan, Alim-Abdul A.; Gelmboldt, V. O.; Хома, Руслан ЄвгенійовичHexamethylenetetramine (HMTA) is a ligand in the synthesis of coordination compounds and also is used as a pharmaceutical antiseptic drug and as hexogen precursorДокумент Preparation and Some Physicochemical Properties of Benzylammonium Sulfates(2014) Khoma, Ruslan E. ; Ennan, Alim-Abdul A.; Gelmboldt, V. O.; Shishkin, O. V.; Baumer, Vyacheslav N.; Mazepa, A. V.; Brusilovskii, Yu. E.; Хома, Руслан ЄвгенійовичNew method of preparation of multisubstituted benzylammonium cations via interaction in the SO2–L–H2O systems (L is benzylamine, α-phenylethylamine, N,N-dimethylbenzylamine, or dibenzylamine) has been developed. The products have been studied by X-ray diffraction, IR, Raman spectroscopy, and mass spectrometry.Документ Products of Interaction between Sulfur(IV) Oxide and Aqueous Solutions of Hexamethylendiamine and tert Butylamine: The Crystal Structure of Hexamethylenediammonium Sulfate Dihydrate(2012) Khoma, Ruslan E. ; Ennan, Alim-Abdul A.; Shishkin, O. V.; Baumer, Vyacheslav N.; Gelmboldt, V. O.; Хома, Руслан ЄвгенійовичThe possibility of mild SO2 oxidation in sulfur(IV) oxide–alkylamine–water–oxygen systems is demonstrated to yield onium sulfatesДокумент Synthesis and Structure of Aminoguanidinium Sulfite Monohydrate(2013) Khoma, Ruslan E. ; Gelmboldt, V. O.; Baumer, Vyacheslav N.; Shishkin, O. V.; Koroeva, Larysa V.; Хома, Руслан ЄвгенійовичThe reaction between sulfur(IV) oxide and an aqueous suspension of aminoguanidinium hydro carbonate yields (CN4H7)2SO3 ⋅ H2O, an “onium” sulfite, which has been characterized by X ray diffraction and IR spectroscopy and mass spectrometry. The structure of the salt is stabilized by numerous H bonds, such as NH⋅⋅⋅O, OH⋅⋅⋅O, and NH⋅⋅⋅N. The incorporation of pyramidal ions into the network of H bonds is accompanied by the lowering of their symmetry in comparison with C3v, thus complicating the IR spectra of the salt in the region where the vibrations of the anion appear.Документ Synthesis and Structure of N (Hydroxyethyl)ethylenediammonium Sulfite Monohydrate(2014) Khoma, Ruslan E. ; Gelmboldt, V. O.; Shishkin, O. V.; Baumer, Vyacheslav N.; Puzan, A. N.; Ennan, Alim-Abdul A.; Rakipov, I. M.; Хома, Руслан ЄвгенійовичA reaction between sulfur(IV) oxide and aqueous N (2 hydroxyethyl)ethylenediamine yields onium sulfite of composition (HOCH2CH2NH2CH2CH2NH3)SO3 ⋅ H2O, which has been characterized by X ray diffraction, IR spectroscopy, and mass spectrometry. The three dimensional structure of the salt is sta bilized by numerous hydrogen bonds, such as NH⋅⋅⋅O and OH⋅⋅⋅O.Документ Synthesis, Crystal Structure, Vibrational Spectra, and Thermochemical Transformations of Tris(hydroxymethyl)aminomethane(2014) Khoma, Ruslan E. ; Gelmboldt, V. O.; Shishkin, O. V.; Baumer, Vyacheslav N.; Ennan, Alim-Abdul A.; Хома, Руслан ЄвгенійовичA practically promising compound, tris(hydroxymethyl)aminomethane sulfate ((TRISH)2SO4, C8H24N2O10S) was synthesized and studied by a set of experimental methods (elemental analysis, IR and Raman spectroscopy, mass spectrometry, thermogravimetry).
