    • IN WHICH Ar is thienyl, phenoxyphenyl, phenyl or substituted phenyl and X is a trifluoroacetate, trichloroacetate, chloride or bromide anion. The compounds are prepared by (a) oxidation of 4iodo-3,5-dimethylisoxazole to 3,5-dimethyl-4(bis(trifluoroacetoxy)iodo)isoxazole, and condensation of the latter with the corresponding activated aromatic compound, ArH or (b) acid-catalyzed condensation of a diacetoxyiodobenzene with 3,5-dimethylisoxazole when the benzene nucleus has halo substitution, i.e., for electrophilic substitution on the isoxazole ring. The compounds have antimicrobial activity.

    • 湿法烟气脱硫(WFGD)系统中使用的含石灰石的浆料的石灰石溶解速率通过加入铵离子而增强。 铵离子可以通过将含有石灰石的浆料气体或氨水和/或水溶性铵盐如硫酸铵,氯化铵或碳酸铵掺入而获得。 增加在WFGD系统中使用的含石灰石的浆料的石灰石溶解速率允许使用石灰石颗粒,较低的石灰石化学计量和较低的浆料循环利用率,从而节省资本和运营成本。 铵离子可以在该过程中回收和重复使用。
