Results and discussion
Any other information on results incl. tables
EU Risk Assessment on the major component of C4 Hydrocarbons: 1,3-Butadiene:
Testing of oxidising properties of 1,3-butadiene is not applicable because it does not contain functional groups capable of producing an oxidising effect. However olefins with allylic hydrocarbons are prone to peroxide formation and 1,3-butadiene will readily form butadiene polyperoxide, (C4H6O2)x, in the presence of oxygen. At lower temperatures this is an alternating copolymer of butadiene and oxygen, although at elevated temperatures (>50°C) the proportion of oxygen decreases. Butadiene polyperoxide is nearly insoluble in liquefied butadiene and separates out to form ¿globules¿ which settle to form a viscous residue. Butadiene polyperoxide is prone to self-heating and above a critical radius will result in explosive decomposition (Alexander, 1959).
Applicant's summary and conclusion
- Executive summary:
According to EU Risk Assessment Report (2002) the major component of C4 Hydrocarbons: 1,3 ¿butadiene does not have oxidising properties (it does not contain functional groups capable of producing an oxidising effect).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
