Hazard Predictions

• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive
• Polymerization hazard: Polymerization reaction may become intense and may cause pressurization

Propylene oxide and NaOH exothermically polymerize; reaction heat can be sufficient to cause spontaneous explosion and fire (MCA Case History No. 31, Case Histories of Accidents in the Chemical Industry, Washington, Manufacturing Chemists' Association).

Bases initiate exothermic polymerization in 1-chloro-2,3-epoxypropane (M. Sittig, 1981, Handbook of Toxic and Hazardous 365bet娱乐, Park Ridge (NJ), Noyes Data Corp., 2nd ed., pp. 23).

Liquid 1-chloro-2,3-epoxypropane ignites on contact with potassium tert-butoxide (Manwaring, R., et al. 1973. Chemistry and Industry 172).

Ethylene oxide violently polymerizes on contact with bases, including metal hydroxides and ammonia (Gupta, A.K. 1949. J. Soc. Chem. (Ind.) 68:179; Troyan, J.E. et al. 1968. Loss Prevention 2:125-30).

Flammable hydrocarbons were released during decomposition in the latter stages of a runaway polymerization reaction between bases and epoxides (Thermal Decomposition of Polymers by Craig Beyler and Marcelo Hirschler, Section 1, Chapter 7, p 1-128).
