Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Additional physico-chemical information: Results from different independent sources indicating the following propierties:
Aziridine may polymerize explosively. Polymerization may be caused by elevated temperature, oxidizers, peroxides, or sunlight. Uninhibited monomer vapor may form polymer in vents and other confined spaces.
Aziridine is very reactive chemically with acids and it is subject to aqueous auto-catalysed exothermic polymerisation, which may be violent if uncontrolled by dilution, slow addition or cooling. It is normally stored over solid caustic alkali, to minimise polymerization catalysed by presence of carbon dioxide.
Aziridine gives the explosive 1-chloroazidine on treatment with chlorinating agents, eg sodium hypochlorite solution. Explosive silver derivatives may be formed in contact with silver or its alloys, including silver solder, which is therefore unsuitable in handling equipment. Aziridine is very reactive chemically with acids and it is subject to aqueous auto-catalysed exothermic polymerisation, which may be violent if uncontrolled by dilution, slow addition or cooling. It is normally stored over solid caustic alkali, to minimise polymerization catalysed by presence of carbon dioxide.
In the preparation of a series of substituted phenylethylenediamines, it is essential to add the reagents to an aromatic solvent at 30-80 ºC in the order aniline, then aluminium chloride, then ethylenimine to prevent uncontrollable exothermic reaction.
