Abstract
processo de purificação de co~ 2~de alcanolamina. um processo de purificação de amina co~ 2~utiliza uma mistura absorvente consistindo de um sorvente co~ 2~de alcanolamina, em combinação com uma base não-nucleofílica. a alcanolamina tem locais de oxigênio e nitrogênio capazes de ataque nucleofílico no átomo de carbono co~ 2~. a adição nucleofílica é promovida na presença da base não-nucleofílica, relativamente mais forte, atuando como um aceitador de prótons. o promotor de base não-nucleofílica, que pode também atuar como um solvente para a alcanolamina, pode promover a reação com o co~ 2~em cada um do(s) grupo(s) reativos de hidroxila e amina nucleofílica das alcanolaminas. no caso de amino alcanolaminas primárias, o co~ 2~pode ser absorvido por uma dupla reação de carboxilação em que dois mols de co~ 2~são absorvidos pelos grupos de amina primária reagindo.
