Commercial and laboratory samples of polyoxypropylenepolyols were studied by 1H NMR spectroscopy at operating frequencies of 100 and 500 MHz. Various methods depending on the solvent used were suggested for determining the equivalent weight (molecular weight of the polyether per terminal hydroxy group). The 1H NMR data are compared to the data obtained by chemical methods and gel permeation chromatography. © 2010 Pleiades Publishing, Ltd.

The influence of the nanocrystalline structure of an aluminum-zinc spinel support on the catalytic activity of bimetallic Pt-Sn catalysts in dehydrogenation of 2-methylbutane was studied. The formation of the spinel structure in solid-phase reactions of aluminum and zinc oxides was examined. © 2010 Pleiades Publishing, Ltd.

Regular trends in variation of the solubility of potassium phosphates in the polyether-water system depending on the physicochemical parameters of the process and kind of the polyether were examined. The residual solubility of potassium dihydrogen phosphate was studied in relation to the temperature, water content, and kind of the polyether being purified. © 2010 Pleiades Publishing, Ltd.
