CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Triisobutyl aluminum appears as a colorless liquid. |
|---|---|
| Color/Form | CLEAR COLORLESS LIQUID |
| Boiling Point | 414 °F at 760 mmHg (USCG, 1999) |
| Melting Point | 33.8 °F (USCG, 1999) |
| Flash Point | -23 °C (closed cup) |
| Density | 0.788 at 68 °F (USCG, 1999) - Less dense than water; will float |
