Ethylene Oxide → 2-(Hexylamino)ethanol

Participants

Reaction Steps

In an alternate synthesis scheme for n-hexyl ethanolamine, the ethoxylation steps remained the same as above in sequence, temperature and pressure. However, the preferred weight fraction of n-hexyl amine to ethylene oxide was lowered to approximately 88 pounds n-hexyl amine to 12 pounds ethylene oxide to yield 100 pounds of reaction mass. The weight ratio of mono to di ethoxylates in the reaction mass was approximately 4.0-4.2 mono to 1.0 di. The purification section was also the same except the process was stopped after removal of n-hexyl amine overhead. The final bottoms fraction contained n-hexyl ethanolamine and some diethoxylates byproducts (less than 20% by weight).
