Abstract��
Both the density and the viscosity of E-44 epoxy resin solution are measured at different temperature.The effect of the volume ratio of E-44 epoxy resin to benzene on phase entrainment is investigated with �� 50mm centrifugal extraactor.The relation between operating factors(rotor speed the flow rate and the flow ratio)and the purifying effect is studied with �� 50mm centrifugal extractor too.The plant test is carried out with �� 230mm centrifugal extrator.When benzene was added into E-44 epoxy resin,the content of chlorine in the E-44 epoxy resin is less than 5mg/L after purification.Without adding bezene,the content of chlorine in the E-44 epoxy resin is less than 100mg/L after purification.
