Darstellung · 1 Eintrag

synthetischeIsobutylbenzene synthesis: Isobutyrophenone, underwent a Wolff–Kishner reduction using hydrazine hydrate and strong base conditions to synthesize isobutyl benzene. The solvent for this reaction was replaced with the more sustainable solvent glycerol. The glycerol for this reaction was obtained from the synthesis of biodiesel. The reaction was allowed to heat at reflux (149–155 °C) for a period of three hours. An average 51 % yield of isobutyl benzene was obtained from the solar synthesis, compared to a 55 % yield from an in-lab, electrical heating analysis.

Ergänzende Hinweise

DefinitionChEBI: Isobutylbenzene is an alkylbenzene that is benzene carrying an isobutyl substituent.
