Synthesis of 2,5-disubstituted pyrroles by the reaction of ketoximes with 1,2-dibromopropane

Conclusions The reaction of ketoximes with 1,2-dibromopropane in the KOH-DMSO system gave 2,5-disubstituted pyrroles in 21–56% yield.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2175–2177, September, 1988.     

Electric discharge treatment of the surface of bentonite clay containing montmorillonite

The electrification of solid porous adsorbents of the clay type was studied. It was found by the thermally stimulated relaxation method that clays contained centers of the accumulation of surface and volume charges. Adsorbent structural changes were studied by X-ray diffraction. Original Russian Text ? A.M.

Extraction separation and cleaning of sewage waters by organic solvents with recirculation

The technology of separation and cleaning of sewage waters from organic compounds by their extraction from water solution by isopropyl ether with its further separation and return for reuse is proposed and well founded. Results of the experimental investigations and kinetics of the liquid phase extraction of organic compounds from sewage waters are reported.
