Ratio of Protein Fractions in Cereal Grains Cultivated in Uzbekistan

The glutelin fraction was used as the food value index of local corn. The base-soluble fraction was used as a test of the glassiness of local strains of rice grain. The content of gliadins and glutelins did not change over 24 h after wheat grain cultivated in Uzbekistan was moistened.     

Iron complexes with monocarboxylate anions: Models of their formation

The composition, stability, existence ranges, and degrees of accumulation of iron complexes in solutions of formic, acetic, propionic, butyric, and valeric acids have been determined with the use of the oxidation function and suggested principle of equilibrium modeling from the experimental data obtained by the oxidation potential method. The calculated model parameters can serve as the reference material for targeted synthesis and different thermodynamic calculations.     

Organophilization of Na+-montmorillonite with polyfluorinated alcohols

Modification of Na⁺-montmorillonite with polyfluorinated alcohols was performed. The structure of the modified Na⁺-montmorillonite was studied by derivatography and Fourier IR spectroscopy. The effect of calcite as clay component on the capability for physical and chemical binding of polyfluorinated alcohols was revealed.     

One-pot catalytic synthesis of crown-like macroheterocycles

An efficient procedure has been developed for the synthesis of crown-like N-cycloalkyl-1,5,8-trithia-3-azacyclodecanes and N-cycloalkyl-1,11-dioxa-4,8-dithia-6-azacyclotridecanes by recyclization of saturated oxathiacycloalkanes with carbocyclic amines in the presence of SmCl₃ · 6 H²O as catalyst.     

Effective synthesis of <Emphasis Type="Italic">N</Emphasis>-substituted 1,3,5-dithiazinanes by reactions of <Emphasis Type="Italic">N</Emphasis>-methyl-1,3,5-dithiazinane and 1,3,5-trithiane with aromatic amines

A novel procedure has been developed for selective synthesis of N-aryl-1,3,5-dithiazinanes, 1,2,6,7-tetrahydro-3,5,1,7-benzodithiadiazonine, and 6,7-dihydro-1,3,5,7-benzotrithiazonine by reactions of aniline derivatives with N-methyl-1,3,5-dithiazinane or 1,3,5-trithiane in the presence of transition and rare earth metal salts and complexes.
