Tate's entrainer method was utilized to determine moisture in polyethylene glycols and carbowax compounds. As the entrainer, benzene, toluene, and xylene were examined and it was found that benzene and toluene would be suitable because they entrain up to 99.7% moisture while xylene entrains only about 90%. The time required until the maximum entrainment of moisture was over 150minutes with toluene and over 240minutes with benzene.
