Separation of methylpentenes from hydroperoxide derivatives thereof

摘要

Methyl pentenes are separated from methylpentene hydroperoxides by distillation in the presence of an inert liquid diluent, e.g. benzene, having an atomospheric boiling point in the range 67-92 DEG C. The distillation may be carried out at a pressure of 150 mm. of mercury to atmospheric pressure. The overhead fraction, which contains the methylpentenes, may be further fractionated to separate olefin from diluent and any oxy-compounds that may be present.
