  Synthesis of reference substances for highly polar metabolites of nitroaromatic compounds

  摘要：

  Transformation processes of nitroaromatic compounds (NAC) lead to polar and highly hydrophilic metabolites. For the unequivocal identification of proposed metabolites reference substances are needed. Since most of them are not commercially available, their synthesis was done in our group. In many cases no satisfying synthesis schemes were found in the literature. In this communication, we therefore describe the preparation, structural elucidation and separation of 17 compounds. Many of the newly synthesized analytes were found in various water samples from a former ammunition plant, (C) 1999 Elsevier Science Ltd. All rights reserved.

  A deodorizer is disclosed which is superior both in odor elimination effect eliminating an already existing odor and in odor prevention effect preventing odor occurrence, without leaving a colored trace on an application site. The deodorizer of the present invention comprises a salt of copper (II) ion and/or zinc ion; at least one acid component selected from the group consisting of alkylsulfonic acids having 1 to 6 carbon atoms, arylsulfonic acids having 5 to 14 carbon atoms, amidosulfuric acids, and derivatives thereof; and water being a solvent. The acid component may be substituted by at least one selected from the group consisting of amine groups, imine groups, and hydroxyl group. The deodorizer comprises the salt in an amount of more than 0.001 mM and less than 10 mM.
