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).

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.

This material is used as a catalyst in organic synthesis.

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respira- tion with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with run- ning water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical obser- vation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

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.

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.

clear liquid

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

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.

Pale amber liquid

ChEBI: Dibutyl phosphate is a dialkyl phosphate.

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

Nonflammable

Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Prior toworking with this chemical you should be trained on its properhandling and storage. Dibutyl phosphate must be stored toavoid contact with strong oxidizers, such as chlorine, chlorinedioxide, and bromine, since violent reactions occur.

Two initial threshold screening levels (ITSLs) for dibutyl phosphate, included an JTSL of 86 μg/m3 based on an 8-hour averaging time, and an ITSL of 170 μg/m3 based on a 1-hour averaging time.
