4 7: Nitration of Alkanes

Mixtures are obtained nitration of propane gives not only 1- and 2-nitropropanes but nitroethane and nitromethane: In commercial practice the yield and product distribution in nitration of alkanes is controlled as far as possible by the judicious addition of catalysts (e g oxygen and halogens) which are believed to raise the concentration of alkyl radicals

Roads to Nitroethane Hive Chemistry Discourse

Re: Roads to Nitroethane Bookmark The sodium ethyl sulfate should be a solid but it is probably low-melting so at the reaction temperature I believe that the mixture is a melt Also there is no solvent needed the reaction is what is called a destructive distillation where the reactants breaks down into product (nitroethane which distils

Electrophilic nitration of alkanes with nitronium

28 10 1997Nitration of alkanes such as methane ethane propane n-butane isobutane neopentane and cyclohexane was carried out with nitronium hexafluorophosphate in methylene chloride or nitroethane solution Nitration of methane albeit in poor yield required protolytic activation of the nitronium ion

Key Performance NITROETHANE [NE

The acute oral LD50 for nitroethane in the Sprague-Dawley strain of rat is estimated to be 1625 193 mg/kg of body weight Thus nitroethane is classified by toxicologists as slightly toxic following oral administration since it is within the toxic range of 500 to 5000 mg/kg Should accidental ingestion occur promptly induce vomiting
