Incompatible materials

1-Chloro-2,3-epoxypropane, the mono- and di-2,3-epoxypropyl ethers of 1,4-butanediol, and 2,2-bis(4(2',3'-epoxypropoxy)phenyl)propane can, in the presence of catalytic quantities of halide ions, cause dehydrochlorination of trichloroethylene to dichloroacetylene, which causes minor explosions when the mixture is boiled under reflux. ... /Trichloroethylene; Epoxides/
