107-66-4 Usage

Uses

Pale amber liquid

Potential Exposure

This material is used as a catalyst in organic synthesis.

Chemical Properties

Dibutyl phosphate is a pale amber to brown, odorless liquid.

Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits toxic fumes of POx. See also PHOSPHATES.

Shipping

UN1760 Corrosive liquids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required. UN3261 Corrosive solid, acidic, organic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required.

Incompatibilities

Dibutyl phosphate is a medium strong acid. Incompatible with oxidizers (chlorates, nitrates, per- oxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Attacks many metals forming flammable and explosive hydrogen gas. Attacks some plas- tics, rubber, and coatings.

Health Hazard

Dibutyl phosphate is an irritant of the eyes and mucous membranes.

General Description

Pale-amber odorless liquid. Mp: -13°C, bp: 135-138°C. Density: 1.06 g cm-3. Moderately soluble in water (18 g / L at 20°C).

Chemical Properties

clear liquid

Reactivity Profile

Dibutyl phosphate Is non-flammable, but combustible (flash point 188°C). Auto-ignition temperature is 420°C. Emits irritating or toxic fumes in a fire. Is a moderately strong acid obtained by the partial esterification of phosphoric acid. Reacts exothermically and vigorously with bases. Incompatible with strong oxidizing agents, alkali metals, heat, or plastic. Reacts with many metals liberating flammable/explosive hydrogen gas.
