GENERAL DESCRIPTION OF MORPHOLINE | ||
Morpholine is a hygroscopic, weak basic, oily and volatile liquid; with a
characteristic amine odor; melting point -5 C, boiling point at 129 C; miscible
with water and with many alcohol organic solvents such methanol, ethanol,
acetone, ethers, BTX (it is used as a solvent itself), but has limited
solubility in alkaline solutions. It decomposes on heating resulting toxic
nitrogen oxides and violently reacts with strong oxidants resulting fire hazard
and attacking copper and its compounds. It can be prepared by the reductive
ammonation of diethylene glycol with hydrogen, by the dehydration of
diethanolamine with a strong acid (oleum) and by heating bis(chloroethyl)ether
with excess ammonia. It is a cyclic amino ether as well as a secondary amine.
1,4-Dioxane is the form which nitrogen atom is replaced by oxygen. The ether
property of morpholine is typically inert. The secondary amine property
involves in the most chemical reactions. Morpholine is a versatile chemical. It is
used as a solvent itself for resins, dyes, and waxes. Its alkyl derivatives
(e.g. N-methylmorpholine, N-ethylmorpholine) are used as a catalyst for the
production of polyurethane foams. Nitrogen in ring system involves in the introduction
of sterically demanding asymmetric center to achieve
effective stereocontrol. Morpholine has a similar volatility with water.
It is used as a pH adjustment additive in fossil fuel and steam systems as
a corrosion inhibitor. The most important use is as a chemical intermediate to
prepare below compounds:
