UN 2413 Quick Details
UN 2413
Product name: Tetrapropyl orthotitanate
DOT Class: 3
Placard type: Flammable
ERG Guide: 128 (check current ERG)
Initial isolation: ERG 128: Small spill - isolate 30m all directions; Large spill - isolate 150m all directions; Fire - isolate 800m and consider evacuation in downwind direction
Common Hazards of UN 2413
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
- Vapors may travel to source of ignition and flash back.
- Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas
- Vapor explosion hazard indoors, outdoors or in sewers.
- Those substances designated with a (P) may polymerize explosively when heated or involved in a fire.
- Runoff to sewer may create fire or explosion hazard.
- Containers may explode when heated.
Chemical Identity & Physical Properties
| Also known as | Titanium tetra-n-propoxideTitanium(IV) propoxideTetra-n-propyl orthotitanateTitanium n-propylateTetrapropoxytitanium |
| CAS Number | 3087-36-3 |
| Appearance | Clear to pale yellow liquid with a mild alcoholic odor. Sensitive to moisture and hydrolyzes in the presence of water to form propanol and titanium compounds. |
| Flash Point | 47°C (117°F) |
| Boiling Point | 232°C (450°F) with decomposition |
| Vapor Density | ~9 (heavier than air) |
| Water Reactivity | Reacts with water and moisture, hydrolyzing to produce propanol and titanium dioxide; avoid water contact |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2413
Extinguishing Media
Dry chemical, CO2, foam designed for polar solvents (alcohol-resistant foam); water may cause hydrolysis but can be used cautiously for cooling
PPE Requirements
⚠️ Level B minimum recommended; full face SCBA required in enclosed spaces or fire situations; chemical-resistant gloves and suit to prevent skin contact
Isolation & Evacuation
ERG 128: Small spill - isolate 30m all directions; Large spill - isolate 150m all directions; Fire - isolate 800m and consider evacuation in downwind direction
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 128).
First Actions for a UN 2413 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
- Consider initial downwind evacuation for at least 300 meters (1000 feet).
