GTA(Glycidyl-triethylammonium chloride) was synthesized by using triethylamine instead of trimethylamine under ultrasonic condition.The reaction was under better controlled when liquid tertiary amine was used.The reaction time was decreased when ultrasonic technology was applied.The best conditions for the synthesis of GTA were: ultrasound frequency was 40 kHz,the reaction temperature was 25 ℃,n(EPIC):(TEA) was 1:1.5,pH value was 7~7.5,the reaction time was 0.5 h.The yield was 97.61%,epoxy value was 91.57%,melting point was 138~140 ℃.
