A water-soluble benzoindole spiroxaxine quaternary ammonium salt additive and its preparation and use (by machine translation)
The present invention discloses a water-soluble benzoindole spiroxaxine quaternary ammonium salt additive and its preparation and use, and is characterized in that the 1 – ethyl – 3, 3 – dimethyl – 2 – methylene-indoline and 1 – nitroso – 2, 7 – naphthalene diphenol as a raw material, preparation 9 ? with phenolic hydroxyl at the piperazine compound. The latter with dibromo butane in the reaction under alkaline conditions, to obtain 9 ? bit has a Br active point of the intermediate. 9 ? bit has a Br active point of the intermediate reaction with triethylamine, recrystallization purification to obtain water-soluble benzoindole spiroxaxine quaternary ammonium salt additive, it has good water-solubility, thermal stability and anti-fatigue characteristics, is applied to the aqueous polyurethane coating, polyacrylic acid coating or polyvinyl alcohol slurry field.
