摘要：
In purifying a normally solid organic peroxide by heating an aqueous suspension of the organic peroxide in an impure state to a temperature above the melting point of the peroxide for converting the suspension to an aqueous emulsion and then separating the resulting aqueous and liquid peroxide phases so that the separated peroxide phase can be solidified by cooling; the heating of the aqueous suspension is effected by injecting finely divided steam therein during its continuous transport in one or more paths leading to the separator for obtaining complete melting immediately prior to entry of the emulsion into the separator without substantial decomposition of the organic peroxide.
