What is Triisopropanolamine TIPA?
Triisopropanolamine (TIPA), with the chemical formula of C9H21NO3, belongs to the tertiary amine and triol class of compounds. Its molecular weight is 191.27 g/mol. The chemical structure of TIPA consists of a central nitrogen atom linked to three isopropanol groups, giving it both amine and hydroxyl functional groups. This dual functionality endows TIPA chemical with versatility, allowing it to be used as a surfactant, chelating agent, pH adjuster, and corrosion inhibitor.
TIPA is typically a colorless to pale yellow viscous liquid at room temperature with a slight ammonia odor. It is readily soluble in water, alcohols, and other polar solvents, making it easy to add to aqueous formulations. Unlike primary and secondary alcoholamines, TIPA’s tertiary alcohol structure gives it greater stability under high temperature and alkaline conditions, a property particularly important in industrial processes such as cement hydration and metal processing.
What Are Main Application of Triisopropanolamine?
>> In the construction industry, as a high-efficiency cement grinding aid
As a key additive in the cement grinding process, its three-dimensional molecular structure provides stronger dispersibility, significantly improving grinding efficiency and reducing energy consumption. Compared to traditional triethanolamine, it can increase the 28-day compressive strength of concrete by 12%, making it particularly suitable for high-temperature construction environments.
>> In the polyurethane industry, as a multifunctional modifier
Crosslinking agent: Reacts with isocyanates to build a three-dimensional network, improving the strength, heat resistance, and wear resistance of products.
Catalyst: Mildly catalyzes the foaming reaction, balancing foaming and gelation rates, and optimizing cell structure.
Performance Regulator: The steric hindrance effect of isopropyl gives products both rigidity and toughness, with better aging resistance than triethanolamine alternatives. Widely used in the production of polyurethane elastomers, foamed plastics, and shoe sole materials.
>> Used as a high-efficiency deacidifying agent in the oil and water treatment industries
In natural gas desulfurization and oil refining, it can be used as an absorbent to selectively remove acidic gases such as hydrogen sulfide and carbon dioxide, generating water-soluble compounds and ensuring the purity of oil and gas products.
In the water treatment field, it is also used to remove acidic impurities from industrial wastewater, reducing the risk of water pollution.
>> Multifunctional Additives
Surfactants and emulsifiers. Used in water-based coatings, detergents, and cosmetic formulations to reduce surface tension and enhance system stability. Its salts formed with long-chain fatty acids exhibit excellent coloring stability, making it an ideal choice for cosmetic emulsification. Metalworking fluid additives. Improve the lubricity and rust prevention of cutting fluids, extending the rust prevention period from 7 days to 30 days.
>> Pesticides and Pharmaceuticals
As a chemical intermediate in the synthesis of herbicides, nitrogen fertilizers, and pharmaceutical raw materials, it can also adjust the PH value of pesticides and enhance solution stability.
>> Applications in New Energy and Electronic Materials
In photovoltaic silicon wafer wire cutting, its extreme pressure lubrication reduces the silicon wafer breakage rate to 0.3% and the cutting wire consumption to 18%.
Its applications in cutting-edge fields such as semiconductor cleaning and carbon fiber impregnation are also making continuous breakthroughs.
What are the excellent properties of TIPA Chemical as a high-efficiency cement grinding aid?
>> High-efficiency dispersion and grinding performance
Its three-dimensional molecular structure (three isopropyl hydroxyl groups and tertiary amine groups) provides super-strong surface activity, enabling it to quickly adsorb onto the surface of cement particles. Through charge repulsion, it breaks the van der Waals forces between particles, preventing agglomeration.
Specifically, it reduces the surface energy of cement particles, increasing particle crushing efficiency by 15-25% and mill hourly output by 10-15%. Optimized particle size distribution increases the proportion of 3-32μm particles (which contribute most to strength) by 3-5%, reduces 45μm sieve residue by over 3.2%, and increases specific surface area by 20.5 m²/kg (at a dosage of 0.05%).
Surface tension regulation capability is 1.8 times that of traditional triethanolamine (TEA), significantly improving cement fluidity and reducing over-grinding by 40%.
>> Full-age strength enhancement characteristics
Early strength (3 days): Promote the hydration of difficult-to-hydrate ferrates, increases mineral hydration level, and increases strength by 10-15%, making it more suitable for scenarios requiring stable setting than TEA.
Late-term strength (28 days): Directional activation of silicate (C3S, C2S) hydration, generating more C-S-H gel, resulting in a 3-12 MPa increase in compressive strength. In high-dosage slag cement, this can even reach a 15% increase, far exceeding the 3-5 MPa increase of TEA.
Long-term strength (60 days): In key projects such as high-speed rail and bridges, a dosage of 0.03% can exceed the strength requirement by 15%, extending building durability by 15-20 years.
>> Activation and compatibility of admixtures
Effectively activates the activity of industrial waste such as slag and fly ash, expanding the range of admixture dosages. In slag cement, the admixture dosage can be increased from 30% to 40% while maintaining strength.
Excellent compatibility with polycarboxylate superplasticizers, early-strength agents, and other admixtures, with no stratification or antagonism, and a stable hydration environment.
Which types of cement can triisopropanolamine (TIPA) be used in?
1. General-purpose Portland cement (PO/PPC)
TIPA Advantages: Low dosage of 0.02-0.05% can increase mill hourly output by 10-15%, and increase 28-day strength by 3-8 MPa. It does not antagonize with polycarboxylate superplasticizers and meets the pumpability requirements of concrete.
2. High-dosage blended cement (slag/fly ash cement)
TIPA Advantages: Targeted activation of waste slag, increasing slag content from 30% to 40% and fly ash content from 20% to 28%, while still meeting 28-day strength standards. Carbon emissions per ton of cement are reduced by 35 kg.
3. Specialty Cement (Ultra-High Strength/Rapid-Hard/Sulfate-Resistant Cement)
TIPA Advantages: With a dosage of 0.05-0.08%, C80 concrete achieves a 15% increase in 3-day strength and reaches over 95MPa in 28 days. Its sulfate resistance coefficient is ≥0.95. The rapid-hardening formula can shorten the final setting time to within 8 hours, making it suitable for 24-hour emergency repair projects.
FAQs of Triisopropanolamine TIPA
