Abstract

Epoxidation of 1,3-butadiene has been studied in acetonitrile solutions of aqueous H2O2 and tetrabutylammonium or 1-ethyl-3-methylimidazolium salts of phosphotungstate anions: [(n-C4H9)(4)N](3){PO4[WO(O-2)(2)](4)}, [(n-C4H9)(4)N](5)Na0.6H1.4[PW11O39] or [(C2H5)(CH3)C3H3N2](5)NaH[PW11O39]. The selectivity of the 1,3-butadiene to 3,4-epoxy-1-butene (EpB) conversion attains 97% at nearly 100% efficiency of the H2O2 consumption. The rate of the EpB formation has been correlated with the solution compositions as found by P-31 NMR under the reaction conditions.
