Dodecylamine acetate is primarily used as a corrosion inhibitor in industrial applications, particularly in oil and gas production. It forms a protective layer on metal surfaces, preventing the damaging effects of corrosive substances like acids and salts. This makes it valuable in pipelines, storage tanks, and drilling equipment to extend their lifespan and maintain efficiency.

In the field of mineral processing, it acts as a flotation agent, aiding in the separation of valuable minerals from ore, such as potash and phosphate ores. Its surfactant properties help in selectively attaching to specific mineral particles, making them hydrophobic and easier to separate.

Additionally, it is utilized in the synthesis of certain organic compounds and as an emulsifier in various chemical formulations. Its antimicrobial properties also make it suitable for use in some biocidal products, helping to control microbial growth in industrial systems.
