Synthesis of N-alkylacrylamides from commercial fractions of higher olefins by the Ritter reaction

Effect of the synthesis conditions on the compositional heterogeneity of copolymers of higher N-alkylacrylamides and butyl (meth)acrylate

“…BAA and OAA were prepared by the Schotten-Baumann reaction from acryloyl chloride and the corresponding amine (nbutylamine or n-octylamine) [16]. NAA was synthesized by the Ritter reaction of acrylonitrile with propylene trimer in the presence of sulfuric acid, following the procedure described in [17]. Prior to use, all the monomers were double-distilled in a vacuum.…”

Modeling and comparative analysis of packing of the polyfractional mixture of B4C powder

“…High-clean boron carbide powder mixtures with 5-15 wt.% of nano additive content (B 4 C-PIHT1, B 4 C-PIHT2, B 4 C-PIHT3, B 4 C-PIHT4) were obtained by combination of mechanical and chemical methods [4]. The initial powder were milled, then purified of the impurities of enriched milled nanopowder particles, rinsed and dried.…”
