Synthesis and anticorrosive properties of alkylammonium polyfluoro-3-(ethoxycarbonyl)-2-oxo-2h-chromen-4-olates
摘要:
Reactions of ethyl polyfluoro-4-hydroxy-2-oxo-2H-chromene-3-carboxylates with amines under mild conditions afforded alkylammonium polyfluoro-3-(ethoxycarbonyl)-2-oxo-2H-chromen-4-olates which efficiently inhibited hydrochloric acid corrosion of mild steel at low concentrations (10(-4)-10(-5) M).
