Isopropanolamines include monoisopropanolamine (MIPA), diisopropanolamine (DIPA) and triisopropanolamine (TIPA). They are offered either as single products or as blends. Monoisopropanolamine (MIPA) is a colorless liquid at room temperature; diisopropanolamine (DIPA) and triisopropanolamine (TIPA) are white solids at room temperature; and mixtures of isopropanolamines are usually in liquid form. Typical grades are commercial and low-freezing, with 10%, 15% or 20% water. Isopropanolamines are used in a wide array of applications, including gas purification, surfactants (primarily for home and personal care products), cosmetic formulations, corrosion inhibitors, metalworking fluids, cement and concrete processing aids, and as emulsifiers, dispersants and wetting agents.
The following pie chart shows world consumption of isopropanolamines:
Isopropanolamines are manufactured by reacting propylene oxide with excess ammonia. The ratio of ammonia to propylene oxide determines which of the three products—MIPA, DIPA or TIPA—is produced. By increasing the ratio of ammonia to propylene oxide, MIPA and DIPA production is favored.
World consumption of isopropanolamines is forecast to grow at an average annual rate of about 5% during 2014–2019, driven by consumption in China, the Middle East, and Other Asia (excluding Japan). In Asia (excluding Japan) and the Middle East, combined consumption is forecast to grow at an average annual rate of about 7%, driven by the increasing use of TIPA for cement applications. These countries/regions, especially China, continue to invest in a great deal of infrastructure—a large consuming application for cement. Consumption of isopropanolamines in North America and Western Europe is fairly mature and will grow at an average annual rate of about 1–2% through 2019. In Central and South America, Central and Eastern Europe, and Africa, consumption is projected to grow at an average annual rate of about 4–5%.
