chloroform is an unstable and is combined with variety of stabilizers to enhance their product life.Sigma-ethanol and amylene stabilized chloroform.and this is used to prevent it from turning into a dangerous gas known as phosgene.
the equation is
Chloroform oxidises in presence of air and forms poisonous phosgene(COCl₂).
CHCl₃ + 1/2 O₂———>COCl₂ + HCl.
To prevent the formation of phosgene, ethanol is used.
COCl₂+ C₂H₅OH————> (C₂H₅)₂CO₃+ HCl
i hope this helps u
