Abstract
(EN)
The implemented embodiments relate to a polyol composition, a propylene glycol composition and a preparation method thereof. The controlled polymerization rate (CPR) of the polyol composition is less than 2.4, and thus a polyol composition appropriate for the application to a following procedure can be obtained. The nitrogen content of the propylene glycol composition is less than 0.4 ppm, and thus a propylene glycol composition appropriate for the application to a following procedure and having enhanced quality can be obtained.
(FR)
Les modes de réalisation mis en oeuvre concernent une composition de polyol, une composition de propylène glycol et leur procédé de préparation. La vitesse de polymérisation contrôlée (CPR) de la composition de polyol est inférieure à 2,4, et ainsi une composition de polyol appropriée pour l'application à une procédure suivante peut être obtenue. La teneur en azote de la composition de propylène glycol est inférieure à 0,4 ppm, et ainsi une composition de propylène glycol appropriée pour l'application à une procédure suivante et ayant une qualité améliorée peut être obtenue.
(KO)
구현예는 폴리올 조성물, 프로필렌 글리콜 조성물 및 이의 제조방법에 관한 것으로서, 상기 폴리올 조성물은 CPR(Controlled Polymerization Rate)이 2.4 미만이고, 이로써 후속 공정에 적용하기에 적합한 폴리올 조성물을 얻을 수 있고, 상기 프로필렌 글리콜 조성물은 질소 함량이 0.4 ppm 미만이며, 이로써 후속 공정에 적용하기에 적합하고 품질이 향상된 프로필렌 글리콜 조성물을 얻을 수 있다.
