摘要

異戊二烯為橡膠工業中重要的原料之一，其相關應用被廣泛研究，但卻鮮少有關其安全資訊方面研究，2011年高雄發生異戊二烯與氧化鋁燒熔太空包事件，引起相關產業的注意。本研究利用微差掃描熱卡計（differential scanning calorimetry, DSC）分析異戊二烯之危害特性，工作內容包含異戊二烯的熱分析、異戊二烯混和氧化鋁放熱反應與異戊二烯混入不相性物質的放熱特性探討，以提供主管機關及產業界參考。結果顯示異戊二烯本身具有易燃性與不穩定性的危害，應避免接觸不相容性物質，本研究結果顯示當失控反應發生時，其放熱量達1,100 J/g，本研究成果將有助於提升產業之製程安全管理。

Isoprene is an important material applied in the rubber industry, which have been extensively studied in application, but safety research was scarce for this substance. In 2011 Kaohsiung, a rubber factory induced fire accidents, which caused relevant industries concerned about the safety information of isoprene. This study focuses on the hazardous properties of isoprene by thermal analysis that contains thermal polymerization of isoprene and exothermic characteristics of isoprene mixed incompatible substances by differential scanning calorimetry (DSC). Isoprene has flammability and instability hazards, if isoprene exposed to air and then contact with fire that will induce fire and explosion. Thermal analysis was carried out for isoprene and mixed with incompatible substances. Results by this study can provide to engineers for avoiding accident.
