2001年5月18日，位于台湾北部的一家丙烯酸树脂制造厂发生破坏性火灾爆炸事故。100多人受伤，包括附近16家高科技公司在内的46家工厂遭到严重破坏。爆炸产生的冲击波摧毁了半公里内许多住宅的大小窗户，直接原因是蒸汽云爆炸，爆炸质量估计相当于1000公斤TNT。然而，最初的原因被发现是一个6吨重的反应器发生的反应失控，其中含有丙烯酸甲酯、甲醇、丙烯腈、异丙醇、丙烯酸、甲基丙烯酸和过氧化苯甲酰。研究和实验结果表明，在失控过程中，温度从60℃迅速上升到170-210℃，最大升温速率可达192K·min(-1)。由于该过程的最终温度远远高于所有反应物的沸点，因此在反应堆内产生的蒸汽被释放到大气中。作为这项研究的一部分，进行了某些危险分析和量热测试，以确保类似的失控事故不会再次发生。(C)2002爱思唯尔科学有限公司。保留所有权利。
On May 18, 2001 a destructive fire and explosion accident occurred in an acrylic resin manufacturing plant located in the northern part of Taiwan. More than 100 people were injured and totally 46 plants including 16 high-tech companies nearby were severely damaged. The resulting blast wave destroyed and shattered many large and small windows of residences within half-a-kilometer.The immediate cause turned out to be a vapor cloud explosion and the blast mass was estimated to be equivalent to 1000 kg of TNT. However, the original cause was found to be a runaway reaction of a 6-ton reactor that contained methyl acrylate, methyl alcohol, acrylonitrile, isopropyl alcohol, acrylic acid, methacrylic acid, and benzoyl peroxide. The investigation and experimental runaway results revealed that during the runaway, the temperature had risen rapidly from 60degreesC to about 170-210degreesC and the maximum temperature rising rate could reach 192 K min(-1). Since the final temperature of the process was much higher than the boiling points of all the reactants, vapors generated inside the reactor were released to the atmosphere. Certain hazards analysis and calorimetric tests to ensure that similar runaway accident should not occur again were performed as part of this study. (C) 2002 Elsevier Science Ltd. All rights reserved.
