WebbThe concentration of propylene chlorohydrin in sodium chloride solution of various concentrations was increased by propylene oxide fumigation temperature and propylene chlorohydrin was affected by the amount of chloride ion. (Fig. 2) Propylene chlorohydrin in foodstuffs was affected by fumigation time (Fig. 3). WebbPropylene oxide can be produced by the chlorohydrin process (involving the reaction of propylene with chlorine) or by the hydroperoxide process (using an organic hydroperoxide to epoxidize propylene [ Kirk and Dempsey 1982 ]). U.S. production of propylene oxide in 1980 was approximately 1,767 billion pounds [ USITC 1981 ].
