CAS No.: 622-40-2
Molecular formula: C6H13NO2
Molecular weight: 131.17300
Physical and chemical properties of hydroxyethylmorpholine
Appearance and properties: transparent colorless to yellow liquid
Density: 1.083 g/mL at 25 °C(lit.)
Melting point: -1 °C
Boiling point: 227 °C757 mm Hg(lit.)
Flash point: 211 °F

Production method
It is obtained by the addition of morpholine to ethylene oxide. Pass ethylene oxide gas into morpholine and react at a temperature below 20°C. After passing, keep warm for half an hour. The residual liquid is distilled under reduced pressure and the fraction is collected at 122-126℃ (1.33kPa) to obtain morpholine ethanol.
