PGMEA Method for production of ultra-highly purified propylene glycol monomethyl ether acetate

The ultra-high purity PGMEA can be effectively produced by controlling the conversion of α-PGMEA to β-PGMEA through a quenching step using an amine compound as a quencher. 초고순도 PGMEA는 반응정지제인 아민 화합물을 이용한 퀜칭 단계를 통해 α-PGMEA로부터 β-PGMEA로의 전환을 제어함으로써 효과적으로 제조될 수 있다....
