Reactivity
ALLYL ALCOHOL presents a dangerous fire and explosion hazard when exposed to heat, flame, or oxidizing agents. Reacts violently or explosively with sulfuric acid, strong bases. Reacts violently with 2,4,6-trichloro-1,3,5-triazine and 2,4,6-tris(bromoamino)-1,3,5-triazine. Reacts with carbon tetrachloride to produce explosively unstable products [Lewis]. Mixing allyl alcohol in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, nitric acid, oleum, sulfuric acid [NFPA 491M. 1991].
