Bis(2-ethylhexyl) phthalate （DEHP）
CAS No.117-81-7

Molecular formula: C24H38O4
Relative molecular mass: 390.56
Structural formula:
1. Performance and use:
Di(2-ethylhexyl)phthalate is a colorless oilyliquid with almost no odor.
Dialkyl phthalate ester plasticizer used to import softness and flexibility to PVC products.
As plasticizer in PVC applications and flexible vinyls.
Bis(2-ethylhexyl) phthalate is commonly used plasticizing agent for PVCs, which as such is a component of blood bank bags, surgical tubing, and other products including food wrappers and children’s toys.
Bis(2-ethylhexyl) phthalate, known by a variety of other names and usually abbreviated DEHP, was patented in 1950 and first used as vacuum pump oil. But since then, it has become the most widely used plasticizer for poly(vinyl chloride) (PVC) and other plastics.
Di(2-ethylhexyl)phthalate (DEHP) is a benzenedicarboxilate ester which is the most widely used plasticizer to soften resins.

3. Packaging and storage
Color Code—Green: General storage may be used.Prior to working with DEHP you should be trained on itsproper handling and storage. Before entering confined spacewhere this chemical may be present, check to make surethat an explosive concentration does not exist. Bis (2-ethylhexyl)phthalate must be stored to avoid contact with oxidizing materials, such as permanganates, nitrates, peroxides,chlorates, and perchlorates, since violent reactions occur.Store in tightly closed containers in a cool, well-ventilatedarea away from heat. Sources of ignition, such as smokingand open flames, are prohibited where bis (2-ethylhexyl)phthalate is used, handled, or stored in a manner that couldcreate a potential fire or explosion hazard. Sources of ignition, such as smoking and open flames, are prohibitedwhere this chemical is used, handled, or stored in a mannerthat could create a potential fire or explosion hazard. Metalcontainers involving the transfer of=gallons or more ofthis chemical should be grounded and bonded. Drums mustbe equipped with self-closing valves, pressure vacuumbungs, and flame arresters. Use only nonsparking tools andequipment, especially when opening and closing containersof this chemical. A regulated, marked area should be established where this chemical is handled, used, or stored incompliance with OSHA Standard 1910.1045.
4. Safety protection
Inhalation can cause nausea and irritation of nose and throat. Contact of liquid with eyes or skin causes irritation. Ingestion can cause abdominal cramps, nausea and diarrhea.
