Efficient Synthesis of Readily Water-Soluble Amides Containing Sulfonic Groups
摘要:
A series of various readily water-soluble amides were synthesized by different procedures. These compounds are useful chemical tracers for assessing the cooling progress in a georeservoir during geothermal power plant operation. Acylation of primary amines was carried out by basically employing the Schotten-Baumann method. As a second method a single-phase solvent system consisting of ethyl acetate as an organic solvent and triethylamine as a catalyst was used. Products were characterized by H-1 NMR and C-13 NMR.
