Partial oxidation of ethylbenzene by H ; modified using iText® 7.1.7 ©2000-2019 iText Group NV (AGPL-version) endobj The conversion of ethylbenzene is more than 90% and the selectivity of acetophenone is more than 95% at 353 K. Graphene can be used as catalyst owing to its unique structures and chemical properties. Noncatalytic Liquid Phase Air Oxidation of Ethylbenzene to 1-Phenyl Ethyl Hydroperoxide in Low Oxygen Volume Fraction. First Step: Friedel Craft Acylation on benzene to form phenyl methyl ketone or acetophenone. Acetophenone carboxylation is shown to be dependent on ATP hydrolysis, reminiscent of but distinct from the related carboxylation of acetone (25). Download PDF's .
