Tri-iso-butyl phosphate, abbreviated as TiBP, is an isomer of tri-n-butyl phosphate (TBP). It is a colorless to light yellow transparent liquid. Compared to TBP, TiBP has a lower viscosity and higher hydrolysis stability due to its branched iso-butyl structure. It is primarily used as an efficient solvent, extractant, and plasticizer, serving as an alternative or complementary option to TBP in various industrial fields.
Chemical Name: Tri-iso-butyl phosphate
English Name: Tri-iso-butyl phosphate
CAS No.: 126-71-6
Molecular Formula: C₁₂H₂₇O₄P
Chemical Structure: [(CH₃)₂CHCH₂O]₃P=O
Appearance: Colorless or light yellow transparent liquid
Odor: Faint characteristic odor
| Property | Description |
|---|---|
| Boiling Point | Approx. 265 °C (decomposes), can be distilled under reduced pressure at approx. 140 °C / 10 mmHg |
| Melting Point | Approx. -70 °C |
| Flash Point | Approx. 145 °C, considered a combustible liquid |
| Density | Approx. 0.965 - 0.972 g/cm³ (20°C) |
| Viscosity | Approx. 3.0 mPa·s (25°C) （Slightly lower than TBP） |
| Solubility | Low solubility in water, miscible with most organic solvents (e.g., alcohols, ketones, esters, aromatic hydrocarbons, aliphatic hydrocarbons) in any proportion. |
| Refractive Index | Approx. 1.418 - 1.422 (20°C) |
| Hydrolysis Stability | Better than TBP, relatively more stable against hydrolysis. |
Many applications of TiBP overlap with TBP, but its unique properties make it more advantageous in certain specific scenarios.
1. Extractant (Primary Application)
Rare Metal Metallurgy: An efficient extractant for the separation of Zirconium (Zr) and Hafnium (Hf). Due to the steric effects of its branched structure, its selectivity for separating zirconium and hafnium can sometimes be superior to TBP, playing an important role in the industrial production of nuclear-grade zirconium and hafnium.
Other Metal Separation: Also used for the extraction and separation of metals such as Vanadium (V), Molybdenum (Mo), and Tungsten (W).
Nuclear Fuel Processing: Can be used as a substitute for TBP or in mixtures with TBP in nuclear fuel reprocessing cycles, though its application is not as widespread or classic as TBP's.
2. Solvent
Coatings and Inks: Used as a high-boiling-point solvent in coatings, inks, and adhesives to improve leveling and prevent blushing.
Cellulose Resin Solvent: Used in the processing of products like nitrocellulose and cellulose acetate.
Chemical Reaction Solvent: Used as a reaction medium in organic synthesis.
3. Plasticizer
Mainly used in nitrocellulose coatings and lacquers as a plasticizer, providing good flexibility and durability to products. However, its plasticizing effect and general applicability are usually not as prominent as mainstream plasticizers like phthalates.
4. Defoamer
Used as a defoamer and anti-foaming agent in industries such as water treatment, papermaking, and textiles.
Typical specifications for industrial-grade TiBP are as follows:
| Item | Specification |
|---|---|
| Appearance | Colorless transparent liquid, free of visible impurities |
| Purity (TiBP) | ≥ 98.0% |
| Acidity (as H₃PO₄) | ≤ 0.05% |
| Water Content | ≤ 0.1% |
| Specific Gravity (20/20°C) | 0.968 - 0.975 |
Packaging: Typically packaged in 200-liter iron drums, plastic drums, or IBC totes. Can be customized according to customer requirements.
Storage: Store in a cool, well-ventilated, dry warehouse away from ignition sources, heat, and strong oxidizing agents. Keep containers tightly sealed.
Transportation: Transport as a general chemical. Protect from direct sunlight, impact, and leakage during transportation.
