sodium peroxide
A nearly white compound (Na 2 O
2 ), having vigorous oxidizing
properties, and used in bleaching mechanical paper
pulps and as a final stage in the bleaching of
chemical paper pulps in some multi-stage bleaching
sequences. It is dangerous to use because, when in
contact with organic matter, it reacts so
vigorously with atmospheric moisture that
sufficient heat can be generate to cause organic
matter to burn or even explode.
