decanted and the entire cycle repeated the resin was slurried and loaded to a chromatography column with a glass frit in the bottom and a stopcock approximately 150 ml of cascamid u00ae c 12 was passed through the bed the cascamid u00ae contained about 5 2 ppm of epichliorohydrin about 10 200 ppm of dichloropropanol and 105 ppm of chloropropanediol a treated sample contained less than 1 ppm of epichlorohydrin less than 2 ppm of dichloropropanol and about 15 5 ppm of chloropropanediol kraft paper was treated with the sample the treated paper had a wet strength of 13 0 lb in a dry strength of 46 5 lb in and a wet dry ratio of 27 9 a sample of kraft paper treated with the untreated cascamid u00ae c 12 had a wet strength of 12 5 lb in dry strength of 45 3 lb in and a wet dry ratio of 27 6 a resin bed was prepared as described in example 1 using amberlyst u00ae a 21 a sample of cascamid u00ae containing about 7 8 ppm of epichlorohydrin about 10 800 ppm of dichloropropanol and 114 ppm of chloropropanediol was treated with this bed a treated sample contained less than 1 ppm of epichlorohydrin less than 2 ppm of dichloropropanol and about 4 5 ppm of chloropropanediol paper treated with the untreated cascamid u00ae had a wet strength of 12 8 lb in a dry strength.
