Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
First-aid measures
Emergency measure - Inhalation: Remove victim to fresh air and obtain medical attention.
Emergency measure - Eyes: Wash immediately with water for at least 15 minutes.
Emergency measure - Skin: Wash the affected area with cool water for approximately 15
minutes, after first removing any contaminated clothing.
Emergency measure - Ingestion: Obtain medical attention.
Fire-fighting measures
Recommended extinguishing agent: Dry chemical or halon are suitable.
Product arising from burning: Products of combustion may contain carbon oxides and soot.
Product determined by test: N
Protective equipment: An approved self-contained breathing apparatus is suitable.
Accidental release measures
Emergency measures in case of spillage: Wear suitable protective clothing (see 2.3.1). Collect the
spillage using a vacuum and transfer to a labelled, sealed
container. Avoid dry sweeping to reduce exposure to a
minimum. Neutralise the spill area with soda ash (sodium
carbonate). Do not allow the substance to enter water
systems. Dispose of spilt material at a licensed facility.
Handling and storage
Handling: Handle under local exhaust ventilation to control dust
levels. If exposure cannot be avoided, wear skin and eye
protection; chemical resistant gloves, eg. neoprene or
vinyl, and safety glasses or chemical safety goggles are
suitable. If airborne exposure is likely a respirator (class
P2) should be worn.
Storage: Store in a clearly labelled, sealed container in a cool,
dry, well ventilated area, away from heat and separated from
oxidisers and alkalis.

Stability and reactivity
Danger other than fire: None reported.
Chemical reaction with water: The substance rapidly hydrolyses in water to give
oxydiphthalic acid.
Disposal considerations
Industry - Possibility of recovery/recycling: Recovery from polymers is not possible.
A method for recycling/reclaiming spilt material that has
not been in contact with water is being developed.
Industry - Possibility of neutralisation: Neutralise with aqueous alkali (eg sodium carbonate or
hydroxide) solution.
Industry - Possibility of destruction: controlled discharge: Discharge following extensive dilution with water, which
will result in the formation of the corresponding acid, is
possible.
Industry - Possibility of destruction - incineration: Incineration at an approved facility is possible, either as
solid or in a combustible solvent.
Industry - Possibility of destruction - water purification: Disposal by this route is possible after pretreatment with
sodium hydroxide to form the sodium salt of the carboxylic
acid.
Public at large - Possibility of recovery/recycling: The substance itself will not enter the public domain.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
