medicinal plants -- Taraxacum koksaghyz rodin -- biologically active substances -- flavonoids -- IR spectrum -- 13С -NMR
Аннотация: In recent years, the interest of researchers in the herbal preparation has grown significantly. Plants are sources of biologically active substances (BAS). In previous articles, the chemical composition and biologically active substances of plants endemic Taraxacum kok-saghyz Rodin growing in Kazakhstan has been studied. Among the BAS of plant origin, inulin and flavonoids occupy a special place. The article examines the release of inulin and flavonoid from the stem of Taraxacum kok-saghyz Rodin plants. In order to isolate a flavonoid, you first need to extract inulin. Due to the fact that in our plants, inulin accumulates up to 40%. Therefore, the first stage was to isolate inulin: with extractions 1:10 with distilled water for 60 minutes, and in the second stage, the further isolation of the residue was first dried, the dry residue was 1:10 with a ratio of 70% ethanol for 3 hours. The inulin yield was -5%, the melting point was 1300C. A The yield of flavanoid is 0.66%, the melting point is 1700 C, the aggregate state is acicular light brown light. The structure of the isolated flavonoid was determined on a Uviline 9100 spectro-photometer; the highest absorption was observed at a wavelength of 364 nm. Consequently, the structure of the isolated flavonoid coincides with the literature data. The maxima of the UV, IR, 13С -NMR. spectrum show that flavonol is a derivative.

thallium amalgam -- chemical preparation -- storage -- decomposition -- sulfuric acid -- water -- wash liquid
Аннотация: It has been established that lNH2SO4 solution and distilled water can be used as a protective medium for a long-term storage (30-40 days) of thallium amalgam of eutectic composition (8.6 mas.%), without sliming of its surface and an insignificant change of its concentration. An inverse dependence between the decomposition reaction rate and the ratio of the solution volume per unit of the contact surface (V:S), which corresponds to the height of the liquid layer (h) above the amalgam, is observed. At h ~ 2.5 cm and higher, the reaction rate becomes stabilized. The value of metal loss during its storage for 10-15 days does not exceed 0.5-1.0 mas.% of the initial thallium content in the amalgam. It has been shown that the rate of dissolution of thallium from amalgam is rather low, and in sulfuric acid solution it is only slightly higher than that in water with all S:V ratios. A similar picture is observed upon thallium amalgam decomposition in the same media in an open vessel; the difference consists only in a higher K value (Table 4). Thus, with S:V = 1:2.5, in an open vessel K in lNH2SO4 makes up 10,5.1011 mol/cm2.sec, and in H2O – 7.3.1011 mol/cm2.sec, whereas in a closed vessel K in lNH2SO4 makes up 1,9.1011 mol/cm2.sec, and in H2O – 1.5.1011 mol/cm2.sec. For 40 days of thallium amalgam (8.54 mas.%) storage in 1NH2SO4 the loss of thallium has been 1.3 mas.%, and in the distilled water - 1 mas.%. The quantity of the dissolved metal increases in proportion to the experiment duration, which is characteristic for a zero-order reaction, and this dependence is observed for all S:V ratios from 1:1 to 1:7. Besides, a possibility to use some saturated hydrocarbons, wherein no sliming of thallium amalgam occurs, as a protective wash liquid has been shown.

stainless steel -- titanium electrode -- alternating current -- iron (II) ions -- chromium (III)ions -- current density -- and current efficiency
Аннотация: Stainless steel is in great demand due to its mechanical strength, heat resistance, and resistance to corrosive environments. This article presents the result of a study of the electrochemical dissolution behavior of a stainless steel electrode (12X18H10T) at polarization by 50 Hz alternating current in a neutral medium (NaCl). Preliminary experiments have shown that the main processes do not take place when two stainless steel electrodes are polarized with an alternating current. It was observed that by the polarization of the “stainless steel – titanium” pair electrodes with alternating current, the alloy is intensively dissolved with the formation of iron (II) and chromium (III) ions. This is due to the "valve" properties of the oxide layer formed on the surface of the titanium electrode. A change in the value of the current density of the titanium and steel electrodes significantly affects the process of electrochemical dissolution of the alloy. At high current densities, the dissolution rate of the alloy decreases due to the deterioration of the current correcting properties of titanium. With an increase in the electrolyte concentration, the current efficiency is reduced as salt passivation occurs. A maximum value of the current efficiency of dissolution of stainless steel was observed at a current frequency of 50 Hz. High frequencies of the alternating current do not provide an adjustable duration of the anodic half-cycle for the oxidation reaction due to the frequent change of half-cycles of the alternating current. It was observed that increasing the temperature of the electrolyte reduces the current efficiency of the electrochemical dissolution of stainless steel electrodes. The effects of main electrochemical parameters on the electrolysis process have been investigated, and the optimal conditions of the alloy dissolution were established (іТі = 60 kA/m2, іSS = 800 A/m2, [NaCl] = 2.0 M, t = 30, ν = 50 Hz.).

Comparison of the results of the cracking of vacuum gas oil on catalysts of the same composition, but with and without a NaMM binder, showed that the introduction of NaMM does not significantly affect the gasoline yield. Samples of catalysts of the same composition, but with the use of Al-pillared MM in Na-and CaNa-exchangeable forms and with the addition of NaMM as a binder, showed similar activity in the yield of gasoline, which is explained by the similarity of the elemental compositions, textural and acidic properties of the studied catalysts. The maximum yield of gasoline, equal to 44.8% and light gas oil of 14.6%, was obtained for Al (2.5) CaNaHMM + NaMM with the addition of a binder and crushing strength of 60-70 N / cm2.
