- 1,2-Benzenedicarboxylic acid, di-2-propenyl ester
- o-Phthalic acid, diallyl ester
Clear pale-yellow liquid. Odorless.
Most diallyl phthalate compounds are sold under military specification and are used in critical electricalelectronic applications requiring high reliability under long-term, adverse environmental conditions. A significant application area is in electronic connectors in communications, computer and aerospace systems. Other uses are insulators, potentiometers, and circuit boards.

Hazards and Protection.
Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Clean up spills immediately, using the appropriate protective equipment. Provide ventilation.
Stable under normal temperatures and pressures.
Can react with oxidizers Incompatible with water and oxygen.
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Extinguishing media: Water spray may cause frothing. Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
This chemical is combustible.
May cause digestive tract disturbances. May be harmful if swallowed.
May cause respiratory tract irritation.
May cause skin irritation.
May cause eye irritation. Lachrymator.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
