Production Methods |
Diisobutyl phthalate is manufactured by esterifying phthalic anhydride and isobutanol in the presence of sulfuric acid. |
|
Air & Water Reactions |
Insoluble in water. |
|
Reactivity Profile |
Diisobutyl phthalate reacts with acids to liberate heat along with isobutyl alcohol and phthalic acid. May react sufficiently exothermically with strong oxidizing acids to ignite the reaction products. Heat is also generated by interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Can generate electrostatic charges in handling [Handling Chemicals Safely, 1980. p. 250]. |
|
Health Hazard |
Vapors from very hot material may irritate eyes and produce headache, drowsiness, and convulsions. |
|
Fire Hazard |
Diisobutyl phthalate is combustible. |
|
Safety Profile |
Moderately toxic by intraperitoneal route. Mdly toxic by ingestion and skin contact. Experimental teratogenic and reproductive effects. Combustible when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. |
|
Definition |
ChEBI: A phthalate ester that is the diester obtained by the formal condensation of the carboxy groups of phthalic acid with two molecules of isobutanol. |
|
General Description |
Oily colorless liquid with a slight ester odor. Denser than water. Insoluble in water. Low toxicity. |
