The research results of maleic anhydride water treatment agents in the past years were summarized and analyzed, which provided reference for further preparation environmental protection agents. A binary copolymer product with excellent scale inhibition dispersion properties was synthesised using sodium allyl sulfonate as monomers. characterized its investigated. It concluded that has performanc...
The title compound {systematic name: poly[[μ(7)-(2R)-2-amino-3-sulfonato-propano-ato]disodium]}, [Na(2)(C(3)H(5)NO(5)S)](n), was obtained through solvent-thermal reaction of l-cysteic acid and aqueous sodium hydroxide. The monomer consists of two Na(+) cations that are coordinated to the deprotonated amino acid. The latter acts as donor utilizing all available coordination sites, viz. the amino...
The two-step synthesis of sodium (2,3,5,6-tetrafluorophenoxy) diethane sulfonate (Na-TFP) is reported, starting from 2,3,5,6-tetrafluorohydroquinone as the precursor. Compared with conventional aqueous electrolytes such 0.5 m NaClO4 and Na2SO4, solution Na-TFP provides higher ionic conductivity over a wide range temperature (e.g., >60 mS cm−1 at 20 °C >70 30 °C) wider electrochemical stability ...
