|
Air & Water Reactions |
Insoluble in water. |
|
Reactivity Profile |
Butyl butyrate reacts with acids to liberate heat along with butyl alcohol and butyric acid. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic 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. May attack some forms of plastics [USCG, 1999]. |
|
Hazard |
Irritant and narcotic. Moderate fire risk. |
|
Fire Hazard |
Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. |
|
Flammability and Explosibility |
Flammable |
|
Safety Profile |
Moderately toxic via intraperitoneal route. Mildly toxic by ingestion. Moderately irritating to eyes, sh, and mucous membranes by inhalation. Narcotic in hgh concentrations. Flammable liquid. To fight fire, use alcohol foam, foam, CO2, dry chemical. Incompatible with oxidizing materials. When heated to decomposition it emits acrid and irritating fumes. |
|
Definition |

|
Aroma threshold values |
Detection: 87 to 1000 ppb |
|
Taste threshold values |
Taste characteristics at 40 ppm: sweet, fresh, fruity, slightly fatty. |
|
General Description |
A colorless liquid. Insoluble in water. A marine pollutant. Poses a threat to the aquatic environment. Immediate steps should be taken to prevent spread to the environment. May penetrate soils and contaminate groundwater and nearby waterways. Mildly irritates the eyes and skin. |
