Composition And Structure

By the interaction of the previously synthesized 2-hydroxypropyl-1,3-bis-estersulfoimide of saccharin-6-carboxylyc acid with alkyl esters of sulfimide of the same acid triestertrisulfoimide saccharin-6-carboxylic acid has been obtained. The composition and structure of the synthesized compound has been confirmed by data of elemental analysis and IR-spectroscopy. The obtained product has been as a curing agent - plasticizer for industrial epoxide resin ED-20. It has been established that the triestertrisulfoimide of saccharin-6-carboxylic acidis the effective curing agent — plasticizer of epoxide resin ED-20. The curing prosses of composition was studied by a method of differential thermal analysis on derivatograph of system “Paulik-Paulik-Erdey”. It has been revealed according to the obtained data that the synthesized triestertrisulfoimide of saccharin-6-carboxylic acidis combined well with epoxide resin ED-20 but it is cured at hard temperature regime. It has been shown that in the introduction of accelerator UP 606/2 into epoxy composition the curing temperature of composition is decreased, but its thermal, physical -mechanical values are increased.

AbstractSorption interlayer complexes of n-butylamine, sec-butylamine, iso-butylamine and diethylamine with homoionic Ln-montmorillonites (Ln = La, Sm, Gd, Er, Y) have been prepared. Compositions of the complexes are of the type: [Ln(butylamine)4]3+ and [Ln-(diethylamine)2]3+. The disposition of amine molecules surrounding the ion, the interaction between the amine group and the Ln3+ ion, and the strength of the ion-dipole bond have been studied by X-ray diffraction, IR spectroscopy and differential thermal analysis.

The growth of NaLa(WO4)2 crystals has been carried out by the hydrothermal method at fairly low P-T conditions. The crystal morphology has been studied with respect to the growth parameters. The crystals obtained were characterized by various techniques such as x-ray diffraction (XRD), differential thermal analysis (DTA), and infrared (IR) spectroscopy.

The aim of this work is to synthesize and study a superabsorbent hydrogel based on starch copolymers. The optimal synthesis conditions have been determined and studies have been carried out on the effect of the molar ratios of the starting materials on the water absorption of the synthesized hydrogel. In the course of research, the optimum copolymerization temperature was 60 °C, and the reaction time was 3 hours. As a result of the study, a hydrogel was synthesized with a starch: acrylamide: bentonite ratio of 10 : 9 : 0.8, respectively. The resulting hydrogel was investigated by IR spectroscopy and differential thermal analysis. The influence of the molecular ratios of starch and acrylamide, as well as the concentration of the initiator, binder and bentonite, affecting the degree of swelling of the synthesized hydrogel, has been studied

The mechanism of fire protection of wood by the modification of a thin surface layer with organophosphorus compounds has been studied. The properties of the modified thin surface layer were studied by X-ray spectral analysis, IR spectroscopy and differential thermal analysis. Promising wood modifiers have been identified and the conditions for effective fire protection of wooden structures with organophosphorus compounds in a thin surface layer have been determined.

Through a combination of thermogravimetry, mass spectrometry and differential thermal analysis, we demonstrate for the first time that all four zeolites show experimental differences in their host-guest interactions with 18C6. In addition, we have estimated the kinetics of 18C6 decomposition, which is a technique that has not been applied to zeolites previously. Using these findings as a toolkit, a more rational use of OSDAs can be utilised to prepare designer zeolites. Furthermore, the new methodologies presented herein can be applied to current zeolites, such as MFI-type zeolites used in the petrochemical industry.
