| Hazard Information | Back Directory | [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. | [Potential Exposure]
This material is used as a catalyst in
organic synthesis. | [First aid]
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. | [Shipping]

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. | [Description]

Dibutyl phosphate is a pale amber to
brown, odorless liquid. | [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. | [Uses]

Dibutyl phosphate is an irritant
of the eyes and mucous membranes. | [Flammability and Explosibility]
Nonflammable | [storage]
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. |
