The lower and upper flammability limits of butenes are 1.6 - 10%. The range reported are based on the data from the members of the butenes category: but-1-ene (CAS 106-98-9), 2-butene (CAS 107-01-7) and 2-methylpropene (CAS 115-11-7).
reported are derived from the members of the butenes category and were
obtained from the CRC Handbook (Lide 2008). This handbook is
peer-reviewed and is considered reliable and suitable for use as a key
study for this endpoint. The lower and upper explosion limits of the
butenes category are 1.6 % - 10 %.Although data are only available from
a single peer-reviewed handbook, the results are very similar across the
different isomers and the consistency of the results between the
structural analogues provides further weight of evidence that the data
lower and upper explosive limits of 2-methylpropene are 1.8 % - 9.6 %
(Lide 2008). The lower and upper explosion limits of 2-butene are 1.7 %
- 9.7 % (Lide 2008). The lower and upper explosive limits of but-1-ene
are 1.6 % - 10 % (Lide 2008). The data would result in a classification
for butenes of category 1 flammable gas and the hazard statement
'extremely flammable gas'.
The lower and upper explosion limits of the
butenes are 1.6 % - 10 %. The data would result in a classification of
category 1 flammable gas and the hazard statement 'extremely flammable
