Secondary organic aerosol formation from the photooxidation of isoprene, 1,3-butadiene, and 2,3-dimethyl-1,3-butadiene under high NOx conditions
Secondary organic aerosol (SOA) formation from atmospheric oxidation of isoprene has been the subject of multiple studies in recent years; however, reactions of other conjugated dienes emitted from anthropogenic sources remain poorly understood. SOA formation from the photooxidation of isoprene, isoprene-1-13C, 1,3butadiene, and 2,3-dimethyl-1,3-butadiene is investigated for high NOx conditions...
متن کاملFuture directions--toxicology studies of 1,3-butadiene and isoprene.
Examination of a profile of data already existing on 1,3-butadiene shows adequate knowledge in many areas of toxicology that are conventionally required in hazard identification. However, while much progress has been made in areas of metabolism and pharmacokinetics, further studies would be worthwhile to improve mechanistic understanding such as the examination of alternate metabolic pathways, ...
متن کاملstudy of ethylene/vinyl acetate transformation to ethylene/vinyl alcohol copolymer by nmr and dsc
hydrolysis of ethylene-vinyl acetate copolymer in alkaline conditions using two systems of naoh/methanol and koh/isopropanol has been studied and the formation of ethylene-vinyl alcohol copolymer was systematically examined using nmr spectroscopy and dsc measurements. vinyl acetate weight percentage and the degree of hydrolysis were calculated from nmr spectroscopy and it is shown that hydrolys...
متن کاملNon-isothermal crystallization and melting of ethylene-vinyl acetate copolymers with different vinyl acetate contents
Non-isothermal crystallization and subsequent melting of three grades of ethylene-vinyl acetate copolymer were investigated by differential scanning calorimetry (DSC) technique. The DSC crystallization curves show that vinyl acetate (VAc) content has the same effect on the onset, peak and final crystallization temperatures, and these copolymers have almost the same spacing of thermal windows un...
