Applications:
- Amine soaps prepared from methoxypropylamine and fatty acids are useful for making dispersion and emulsions of certain synthetic and natural resins and waxes which are useful in floor finishes, textile finishes, water-based paints and in similar areas of application.
- Useful for preparing water-insensitive waxes. It volatilizes with water and leaves behind an insoluble wax film. Further, in dilute solutions does not have an objectionable odor. The material has been compared with morpholine in such applications and may, in fact, function as a substitute for morpholine in some instances.
- Used in insecticide emulsions, dye solvents, textile assistants, and in general, applications in which mild bases of moderate volatility are desired.
- It has been used in the production of dyes to modify polybutadiene-based isocyanates and in the manufacture of polyamide resins.
- The treatment of aluminum and aluminum alloy surfaces with dilute solutions of methoxypropylamine is reported to improve the adherence of various coatings which may be subsequently applied.
- The reaction of methoxypropylamine with bis(2-carbamoylphenyl) disulfides is reported to give products useful in controlling mildew fungi in latex and alkyd paints.
- Similar products are obtained by reacting methoxypropylamine with quinones, carbamates, benzothiazole and other substrates.
- Compounds effective against silicosis have been reported from the reaction of methoxypropylamine with styrene-maleic anhydride copolymer and a diamine.
- Aphenol-free paint remover has been prepared from methoxypropylamine and sodium hydroxide. Plant growth regulators were prepared from this product.
- A fluorescent brightener for cellulosic textiles was prepared from methoxypropylamine. It is reported to have improved low-temperature effectiveness and did not discolor washing powders.
- Water soluble polyelectrolytes for use as flocculating agents have been prepared by reacting methoxypropylamine with acrylonitrile polymers.
- Used to inhibit corrosion in steam condensate systems. The addition of the amine in the parts per million level is effective in reducing corrosion caused by the presence of carbon dioxide in the water.
- An additive to prevent corrosion of oil refining equipment. The presence of acidic materials in the incoming crude causes corrosion at the points of initial water condensation.
