Safety | Decomposes violently when heated above 155°C. May polymerize exothermically when heated above 100°C. Polymerization is catalyzed by traces of acid or base. Reaction with sodium hydroxide forms an explosive salt. The cis- isomer readily cyclizes to form the dangerous 2,3-dimethylfuran. When heated to decomposition it emits acrid smoke and irritating fumes. See also ACETYLENE COMPOUNDS and ALKYNES. | Risk Codes | N/A |
