Isomerization of 3,4-dichloro-1-butene into 1,4-dichloro-2-butene by heterogeneous catalysis

The isomerization of 3,4-dichloro-1-butene into 1,4-dichloro-2-butene was investigated by gas-liquid chromatography in the temperature range of 60-90 °c. fe2o3/tio2 was used as a catalyst. fe2o3/tio2 solid acid catalyst has been prepared by the support saturation method,tested in the isomerization of 3,4-dichloro-l-butene into 1,4-dichloro-2-butene. this catalyst shows a high activity opposite to pure titania in this reaction. the present investigation focuses on the reactivity of titatia supported ferric oxide with iron contents of 5 wt%. in the isomerization of 3,4-dichloro-lbutene into 1,4-dichloro-2- butene. the activation parameters have been evaluated under optimized conditions,using the arrhenius and eyring plots.
