RE: [Histonet] Chlorine gas

From:"Smith, Allen"

It depends on what you use for decalcification.  If you use Hollande's
fluid, formic acid, or EDTA, there is no chloride to be oxidized to
chlorine. My preference for decalcification is Schmorl's fluid
(formalin-formic acid). In theory, formalin can react with hydrochloric acid
to produce the dangerous volatile liquid bis-chloromethyl ether, but the
yield from dilute solutions at atmospheric pressure is trivial.
Nevertheless, if I mixed formalin and HCl I would do it in a fume hood.
Mixing concentrated ammonium hydroxide and sodium hypochlorite ("chlorine
bleach") produces a fairly good yield of chlorine: don't try it!

Has any one heard that mixing decal solution and formalin would cause
the formation of chlorine gas?
