Physicochemical properties of 1,2-epoxycyclopentane

Temperature dependences of density, viscosity, and saturated vapor pressure of 1,2-epoxycyclopentane were studied and approximated by interpolation equations. Its refraction index and chromato-mass-spectroscopy data are given.

     

Efficiency of phase-transfer catalysis in cyclopentene epoxidation with hydrogen peroxide

The effect of the structure and amount of the phase-transfer catalyst (quaternary ammonium salts) and the solvent effect on cyclopentene oxidation with an aqueous hydrogen peroxide solution in the liquid-liquid two-phase system was studied. The phase-transfer catalyst and solvent ensuring high reaction rate and high selectivity with respect to target products were chosen.     

Curing of oligo(diene-isoprene-urethane-epoxy) oligomer in the presence of an active plasticizer, 1,2-epoxycyclopentane, and of its adducts with imidazoles

Curing of a high-molecular-weight low-polarity oligo(diene-isoprene-urethane-epoxy) oligomer PDI-3AK with methylendic anhydride and isophoronediamine in the presence of an active plasticizer, 1,2-epoxycyclopentane, and of its adducts with imidazoles acting simultaneously as catalysts and plasticizers was studied by differential scanning calorimetry in the dynamic mode. The glass transition points and physicomechanical properties of the elastomers were determined.
