Reaction Steps

Though the temperature increased up to 150° C. by the heat of reaction over the length of about 20 mm from the inlet at the initial stage, the temperature came to have a profile barely rising to nearly 150° C. after 500 hrs near the outlet of the catalytic layer. As a result, deterioration in catalytic activity was observed. The results obtained are as follows: the conversion of ethylene oxide was 100%; and the ratio of each component in the produced ethanolamines was: monoethanolamine/diethanolamine/triethanolamine=69/30/1. Diethanolamine was produced at a high selectivity while a small amount of triethanolamine was produced.
