VUV irradiation of carbon dioxide (CO2) and ammonia (NH3) complexes in argon matrix
摘要:
In this study, we characterized by FTIR spectroscopy the 1:1 and 2:1 molecular complexes between NH3 and CO2 in argon matrix at low temperature. In addition we tentatively identified the 1:2 molecular complex. The structures of the complexes were established from B3LYP calculations. Moreover, we showed that the VUV irradiation of the 1:1 complex forms the NH2OH:CO complex. (c) 2008 Elsevier B.V. All rights reserved.

Zinc carboxylate clays and zinc carboxylate organoclays, methods for their preparation, and compositions containing the same are disclosed. The methods comprise either mixing a zinc clay composition with a carboxylic acid, or mixing a carboxylic acid with a zinc ammonia complex solution, then combining the resulting zinc carboxylate salt with a slurry or suspension of a cation-exchangeable clay, to prepare the zinc carboxylate clay. These clays can be further intercalated with quaternary ammonium salts to make zinc carboxylate organoclays. The present clays may be used in compositions and/or as additives in rubber and plastic formulations and products and in catalyst formulations.
