Evaluation of amines as bases for the H2O2hyphen;Cl2singlethyphen;oxygen generation reaction

摘要

The performance of a spargerhyphen;type, singlethyphen;deltahyphen;oxygen generator using various amines as alternative bases to NaOH was found to be comparable to the performance of a generator with the Cl2hyphen;NaOHhyphen;H2O2hyphen;H2O reactant system. Based on the percentage of singlethyphen;oxygen evolution from the generator and the known rates of reaction between Cl2and propylamine, the reaction between Cl2and HOminus;2, which is assumed to produce singlet oxygen, is estimated to be sim;108Mminus;1thinsp;sminus;1.
