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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
