MethoxyPropyl Amine is used for several application such as intermediate in the production of floor waxes, water treating chemicals, emulsifiers, in waterbased paints, as corrosion inhibitor, textile additive, in the production of polyamide resins and other products.
Product Application:
3-Methoxypropylamine is a liquid C3-Aminoether. 3-Methoxypropylamine is used in steam systems as a corrosion inhibitor and to make soaps and emulsions in floor coatings, textile finishes, and paints.
3-Methoxypropylamine (MOPA) is used mainly as a corrosion inhibitor in water treatment systems.
Methoxypropylamine (MOPA) is a clear, colorless slightly viscous liquid with a typical ammonialike odor. It is completely soluble in water.
Product Dose:
When used in combination with hydrazine or another oxygen corrosion inhibitor, the compositions should contain on an active basis from about 1% to about 99% methoxypropylamine and from about 0.1% to about 50%, preferably about 1% to about 15%, of the oxygen corrosion inhibitor.
The compositions of 3-Methoxypropylamine may be fed to the steam condensate system being treated by conventional liquid feeding means or may be fed to the boiler feedwater or directly to the steam supply lines.
Product Note:
3-Methoxypropylamine as a neutralizing amine:
There are several different neutralizing amine components typically used in the treatment of boiler feedwater and/or condensate.
Neutralizing amines each have different chemical properties, and it is important to understand the differences so that the correct components can be applied.
Neutralizing amines typically applied in power plant systems are cyclohexylamine (CHA), methoxypropylamine (MPA), monoethanolamine (ETA), and morpholine.
Neutralizing amines are weak bases that are typically classified in terms of their neutralizing capacity,basicity, and distribution ratio.
The neutralizing capacity is a measure of how much amine it takes to neutralize a given amount of acid.
Usually it is expressed as the ppm of CO2 (or carbonic acid) neutralized per ppm of neutralizing amine.
Once the acid has been neutralized, each amine has a different ability to boost pH, which is accomplished by the hydrolysis of the amine to form hydroxyl (OH-) ions.
Distribution ratio refers to the volatility of the amine, which is one factor that helps determine how each amine component will partition between the liquid and steam phases.
The distribution ratio of a particular amine also influences how much amine is recycled throughout the system, and how much amine will be lost from the system via boiler blowdown and steam venting.
While neutralizing amine chemistry may appear to be relatively straightforward, it is in fact quite complex.
For example, the distribution ratio for a given amine is actually a function of pressure, temperature and pH.
This means if you feed more or less neutralizing amine in a given system and affect the pH, the distribution of the amine between the liquid and steam phases will change as well.
In addition, the chemistry of neutralization is actually based on equilibrium chemistry of weak acids and weak bases.
In many cases, there are multiple neutralizing amine components and acid components present so it becomes even more difficult to predict the amine distribution and pH profile across the system without using sophisticated computerized modeling techniques or without performing extensive empirical in-plant analyses.
The thermal stability of the neutralizing amine must also be considered when designing a treatment program to control FAC.
Most amines degrade to some degree in an aqueous, alkaline, high temperature environment to form carbon dioxide, organic acids and ammonia.
Morpholine, CHA, ETA, and MPA are considered the most thermally stable amines and are routinely employed in high-pressure power plant applications.

Remarks:
Advantages of 3-Methoxypropylamine over Cyclohexylamine and Morpholine:
Neutralizing amines such as cyclohexylamine and morpholine have been used but they have several disadvantages.
For example, cyclohexylamine has a high distribution ratio and accordingly, substantial cyclohexylamine escapes the system through the deaerator vent.
Morpholine, on the other hand, has a low basicity value which means that more morpholine is required to attain high pH in the condensate system and it also has a very low distribution ratio which means that substantial amounts are lost via blowdown.
The neutralizing amine 3-Methoxypropylamine overcomes the above-mentioned disadvantages of cyclohexylamine and morpholine.
3-Methoxypropylamine has a very desirable distribution ratio and a fairly high basicity value.
3-Methoxypropylamine may be used alone or in combination with an oxygen corrosion inhibitor such as hydrazine.
In use, concentrations of 0.1 to 1000 mg/l, and preferably 1 to 100 mg/l, should be maintained in the steam condensate system.
When used in combination with hydrazine or another oxygen corrosion inhibitor, the compositions should contain on an active basis from about 1% to about 99% methoxypropylamine and from about 0.1% to about 50%, preferably about 1% to about 15%, of the oxygen corrosion inhibitor.
