Chemical properties

It is flammable.Its vapor and air can form explosive mixture. In case of open flame and high heat, it is easy to cause combustion and release toxic gas. Reacts violently with oxidants, strong acids, strong bases, amines, and bromine. Under the high temperature of the fire, the exothermic heat of polymerization can occur, causing the container to rupture.
