Dibutyl phosphate Chemical Properties,Uses,Production
Chemical Properties
Dibutyl phosphate is a pale amber to brown, odorless liquid. It is used as a catalyst for cross-linking in the paint industry and antistatics for the textile industry. It is stable in neutral, acidic or alkaline solution, and is classified as "not readily biodegradable" but inhererently biodegradable.The half-life time of 4.99 years is estimated for the degradation of dibutyl phosphate in air by the reaction with photochemically produced OH radicals. (MITI, Japan).
Uses
Dibutyl phosphate is used as a plasticizer for polymer system and hydraulic fluid directly and used as a catalyst for cross-linking in paint industry. It is used as an antifoam agent in ore separation process and as an antistatic agent in the textile industry. It can be used as a precursor for antistatics, as a mould release agent in polyurethane applications and, as a non volatile acidic catalyst soluble in organic media.
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).
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.
Health Hazard
Dibutyl phosphate is an irritant of the eyes and mucous membranes.
Safety Profile
Moderately toxic by ingestion. When heated to decomposition it emits toxic fumes of POx. See also PHOSPHATES.
Potential Exposure
This material is used as a catalyst in organic synthesis.
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.
