    Using trifluoracetyl and tert-butoxycarbonyl protection for amine groups, preparative methods for synthesis of prolylleucylproline have been developed.С использованием трифторацетильной и трет-бутоксикарбонильной аминозащитных групп предложены препаративные методы синтеза пролиллейцилпролина. Физико-химические характеристики полученных образцов трипептида практически совпадают, что может свидетельствовать об отсутствии процессов рацемизации на всех стадиях синтеза пролиллейцилпролина с применением трифторацетильной защитной группы

    The process of the oxidative chlorination of methane carried out in a flow reactor was investigated in the temperature range of 370–400°C under a pressure of 1–9 ata. The catalyst is a mixture of copper chloride, potassium chloride and lanthanum chloride on a porous support. The molar ratio CuCl2:KCl:LaCl3 is 1:1:0.3. The process was studied in an excess of methane at the reactants ratio CH4:HCl:O2 12:2:1 and 13.5:1:0.5. It was shown experimentally that the productivity of the methane oxychlorination reactor increases proportionally to pressure in the degree ~ 0.85. It was found that an increase in the selectivity of the methane oxychlorination process to the desired product – methyl chloride – (more than 90%) is achieved by increasing the ratio of methane to the sum of hydrogen chloride and oxygen.Процесс окислительного хлорирования метана, проводимый в проточном реакторе, изучался в интервале температур 370–400°С при давлении 1–9 ата. В качестве катализатора использовалась смесь хлоридов меди, калия и лантана в мольном соотношении 1:1:0.3, нанесенная на пористый носитель. Процесс изучался в избытке метана при соотношении реагентов CH4:HCl:O2, равном 12:2:1 и 13.5:1:0.5

    Multiple rare-earth ion environments in amorphous (Gd2_2O3_3)0.230_{0.230}(P2_2O5_5)0.770_{0.770} revealed by gadolinium K-edge anomalous x-ray scattering

    A Gd K-edge anomalous x-ray scattering (AXS) study is performed on the rare-earth (R) phosphate glass, (Gd2_2O3_3)0.230_{0.230}(P2_2O5_5)0.770_{0.770}, in order to determine Gd⋯Gd separations in its local structure. The minimum rare-earth separation is of particular interest given that the optical properties of these glasses can quench when rare-earth ions become too close to each other. To this end, a weak Gd⋯Gd pairwise correlation is located at 4.2(1)Å, which is representative of a metaphosphate R⋯R separation. More intense first-neighbor Gd⋯Gd pairwise correlations are found at the larger radial distributions, 4.8(1), 5.1(1), and 5.4(1)Å. These reflect a mixed ultraphosphate and metaphosphate structural character, respectively. A second-neighbor Gd⋯Gd pairwise correlation lies at 6.6(1)Å which is indicative of metaphosphate structures. Meta- and ultraphosphate classifications are made by comparing the R⋯R separations against those of rare-earth phosphate crystal structures, R(PO3_3)3_3 and RP5_5O14_{14}, respectively, or difference pair-distribution function (ΔPDF) features determined on similar glasses using difference neutron-scattering methods. The local structure of this glass is therefore found to display multiple rare-earth ion environments, presumably because its composition lies between these two stoichiometric formulae. These Gd⋯Gd separations are well-resolved in ΔPDFs that represent the AXS signal. Indeed, the spatial resolution is so good that it also enables the identification of R⋯X(X=R, P, O) pairwise correlations up to r∼9Å; their average separations lie at r∼7.1(1), 7.6(1), 7.9(1), 8.4(1), and 8.7(1)Å. This is a report of a Gd K-edge AXS study on an amorphous material. Its demonstrated ability to characterize the local structure of a glass up to such a long range of r heralds exciting prospects for AXS studies on other ternary noncrystalline materials. However, the technical challenge of such an experiment should not be underestimated, as is highlighted in this work where probing AXS signal near the Gd K edge is found to produce inelastic x-ray scattering that precludes the normal AXS methods of data processing. Nonetheless, it is shown that AXS results are not only tractable but they also reveal local structure of rare-earth phosphate glasses that is important from a materials-centered perspective and which could not be obtained by other materials characterization methods

    The article presents studies on the dependence of the crystallization rate of natural honey on the moisture weight ratio, the activity of the invertase enzyme. Based on the results presented, preliminary conclusions can be drawn, which indicate that the higher the activity of the invertase enzyme, the sooner the crystallization of the honey begins
