Refractories and Industrial Ceramics | Year: 2012

Studies are performed with the aim of developing scientific bases and creation of preparation methods based on local raw material resources for a new generation of SHS-refractory materials with high operating properties, making it possible to increase service life (resistance) of metallurgical heating unit linings, and also to improve the quality of metal obtained. A novelty of this research consists of development of scientifically based approaches for resolving this problem, which make it possible to reveal features of unmolded and molded refractory formation, required for effective control of complex physicochemical and production processes for preparing new grades of refractories. © 2012 Springer Science+Business Media New York.

N-(5-Bromopyridyl-2)-2-N′-cytisino-and N′-d- pseudoephedrineoacetamides were synthesized by reaction of the alkaloids cytisine and d-pseudoephedrine with N-(5-bromopyridin-2-yl)-2-bromoacetamide hydrobromide. The compositions and structures of the products were confirmed by IR and PMR spectroscopy and mass spectrometry. © 2010 Springer Science+Business Media, Inc. Source

10-(2-N-Cytisino-), (-anabasino-), and (-d-pseudoephedrino-)acetyl- and -propionylphenothiazines were synthesized by reaction of chloroacyl derivatives of phenothiazine with the alkaloids cytisine, anabasine, and d-pseudoephedrine. The compositions and structures of the products were confirmed by IR and PMR spectroscopy and mass spectrometry. One of several samples showed clearly pronounced antioxidant activity. © 2010 Springer Science+Business Media, Inc. Source
