Graft polymerization of ethyl acrylate onto polyvinyl alcohol using Ce4+ – dextrose redox initiator was written by Chowdhury, P.;Chowdhury, N. D.. And the article was included in Journal of Polymer Materials in 1999.SDS of cas: 14431-43-7 This article mentions the following:
Et acrylate (EA) was graft polymerized onto polyvinyl alc. (PVA) using ceric ammonium sulfate (CAS)-dextrose monohydrate (DM) redox initiator in aqueous medium. The grafting efficiency (GE) of EA was studied as a function of monomer concentration, initiator concentration, time, pH, and temperature The GE was optimum for concentrations of CAS 12.64 × 10-3 mol/L, DM 2.52 × 10-3 mol/L, PVA 2.0 g/L, EA 0.552 mol/L, and H2SO4 0.18 mol/L, temperature 45°C, and time 3.5 h. Acid hydrolysis and IR spectroscopy were used for the confirmation of graft copolymer formation. The X-ray diffraction anal. and TGA of PVA and a representative graft copolymer were undertaken. A mechanism of grafting was suggested. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7SDS of cas: 14431-43-7).
(2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7) belongs to tetrahydropyran derivatives. Tetrahydropyrans are also used as important solvents, as chemical intermediate and as monomer for ring-opening polymerization. The reaction of tertiary 1,4- and 1,5-diols with cerium ammonium nitrate at room temperature gives tetrahydrofuran and tetrahydropyran derivatives in high yield and stereoselectivity. Various fragrant compounds have been synthesized using this method.SDS of cas: 14431-43-7
