colorless liquid, boiling point 138 °c. Flash point 32 °c. Freezing point -63 °c. The relative density was 0. 916. The vapor pressure was 0.813kPa.
with cooling and stirring, morpholine is slowly added with bromoethane, and the reaction temperature is controlled to be below 70 ℃. After feeding, the mixture is refluxed for 6 hours, the oil layer was separated by neutralization with 50% NaOH solution until it was strongly alkaline. The water layer was extracted with ether and then combined with the oil layer.
