MORPHOLINE is a
colorless liquid, hygroscopic liquid with a characteristic amine-like odor. It is completely miscible
with water and a large number of organic solvents and is itself a solvent for a
large variety of organic materials, including resins, dyes, waxes, shellac, and
casein.
MORPHOLINE is an extremely versatiles chemical with many
importants applications. It is used an intermediate in the manufacture of
rubber chemical and optical brightener s. It is also used extensively as a
corrosion inhibitor in steam boiler systems .
Fatty acid derivates of morpholine are used as
emulsifiers in the manufacture of waxes and polishes. Other derivative
chemicals, and antioxidants for lubricating oils. Morpholine derivatives are
particularly useful in the textile industry, where they are employed as textile
lubricants and sizing emulsifiers.
APPLICATIONS :
Corrosion Inhibitors
Morpholine is
widely used as a neutralizing amine in combating carbonic acid corrosion in
condensate return lines of steam boiler systems. The morpholine volatilizes
with the steam from the boiler and condenses when the steam does, thereby
affording protection to the lines, which otherwise would be subjected to
corrosion by the carbonic acid present in the steam condensate.
Morpholine is one of
several amines employed as phosphates for inhibiting the corrosive action of
greaseproof paper on steel and other metals. Di-4-morpholinyl polysulfides have
been claimed as corrosioin inhibitors to be added to mineral lubricating oils.
Turbine oils, especially, are quickly contamined with water, and to protect the
machinery against rusting, 4,4-alkylidenedimorpholines and poly (
4-morpholinylmethyl) phenols have been used. Storage tanks, pipes, and other
device for handling petroleum distillates must be protected against corrosion
and for this purpose 4,4-butylmercaptomorpholine, morpholinium mahogany
sulfonates, and morpholine in conjunction with ammonium mahogany sulfonates
have been suggested.
A number of other morpholine containing compounds have been used as wetting agents, and it is said that morpholinium linoleate is an especially good surface tension depressor for use in rust preventive compositions because it tends to harden the rust preventive film.

Morpholine
vapors protect silver and other metals against corrosion and tarnish by acid
fumes, such as sulfur dioxide and hydrogen sulfide. The morpholine is supplied
by evaporation from solution in a solid, such as camphor, or by sublimation from morpholinium N
N-oxydiethylenecarbamate.
Morpholine is
a component of a corrosion inhibitor system that prevents decomposition of a
chlorinated hydrocarbon in a composition containing the chlorinated hydrocarbon
and a large amount of water.
Corrosion of
metal aerosol containers and valves can be prevented by the use of low levels
of morpholine.
Wax Emulsifiers and Surface-Active Agents
When morpholine is reacted with fatty acids, it forms soaps possessing
excellent emulsifying properties. The oleic soap is a particularly important
emulsifier used in the formulation of self-polishing waxes and polishes. One of
the main advantages of morpholine-based emulsifiers is the similar boiling
points of morpholine and water. When the loosely bound faty acid-morpholine
compound breaks down, the morpholine component evaporates at approximately the
same rate as the water. Consequently, the resultant wax film is left dry and
void of morpholine and is then highly water resistant. This is a very desirable
feature in household and automobile waxes and polishes.
The reaction products of morpholine and tung oil or linseed oil havbe
been found to be good emulsifying and dispersing agents. Also, the quaternary
alkyl ammonium sulfates of Mannich bases from morpholine and mono- or
polyhydric phenols have been patented as emulsifying and wetting agents.
A number of other morpholine containing compounds have been used as wetting agents, and it is said that morpholinium linoleate is an especially good surface tension depressor for use in rust preventive compositions because it tends to harden the rust preventive film.
The morpholine salt of polymeric maleamic acid has been used in
compositions for coating paper, cloth, etc. Small quantities of morpholine have
been incorporated in fireproofing materials, and the stability of certain
asphalt emulsion has been improved by the addition of morpholine. This amine
has also been used as an equalizing and dispersing agent in dye baths and
printing pastes, and its quaternary alkyl ammonium sulfates have been patended
as general surface active agents.
