Product Details
|
Air & Water Reactions |
Flammable. Insoluble in water. |
|
Reactivity Profile |
Organometallics, such as TETRA-N-PROPYL ZIRCONATE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. |
|
Health Hazard |
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. |
|
Purification Methods |
Although it was reported that it could not be crystallised or sublimed even at 150o/10-4mm [Bradley & Wardlaw J Chem Soc 280 1951], the propoxide, when properly prepared, has been purifed by distillation in a high vacuum [Bradley et al. J Chem Soc 2025 1953]. [Beilstein 1 IV 1420.] |
|
General Description |
A yellow-colored liquid with an alcohol-like odor. Has about the same density as water and is insoluble in water. Flash point below 141°F. Vapors are heavier than air. May be irritating to skin, eyes, and mucous membranes. |
