The Dow Chemical Company, the world's largest producer of isopropanolamines and the only U.S. producer, offers grades of MIPA (monoisopropanolamine), DIPA (diisopropanolamine) and TIPA (triisopropanolamine). DIPA is occasionally used in gas treating applications. However, it cannot match the performance of products from Dow Gas Treating Products and Services.
Isopropanolamines are basic chemicals that are used in many applications to achieve basicity, buffering and alkalinity objectives. Because they are good solubilizers of oil and fat, they are frequently used to neutralize fatty acids and sulfonic acid-based surfactants.
DOW monoisopropanolamine (MIPA) is a liquid at room temperature, while diisopropanolamine (DIPA) and triisopropanolamine (TIPA) are white solids. All of the amines, except for monoisopropanolamine, are available in low freezing grades to facilitate handling. Low freezing grades (LFG) contain deionized water (usually 15% by weight).
NOTE: Low freezing grades of isopropanolamines to be heated above 60°C should not be stored in the presence of aluminum, due to the possibility of excessive corrosion and potential chemical reaction releasing flammable hydrogen gas. They should be stored in mild steel; or if iron or color are important, stainless steel is recommended.
