- Health hazard: 急性/慢性危害:该化合物可能是刺激物。加热至分解时释放有毒氯气。(NTP, 1992)
- Hazard summary: 在小鼠致死剂量腹腔注射研究中导致僵直(包括木僵)和肌肉收缩或痉挛(LD50 = 237 mg/kg);[RTECS] 刺激物;[Acros Organics MSDS]
- reactive group: 卤代芳烃
- First aid measures: 摄入:如果受害者意识清醒且没有抽搐,给予1-2杯水稀释化学品,并立即呼叫医院或中毒控制中心。如果医生建议,准备将受害者送往医院。如果受害者抽搐或昏迷,不要经口给予任何东西,确保受害者的气道畅通,并将受害者侧卧,头部低于身体。不要催吐。立即将受害者送往医院。(NTP, 1992)
- Regulatory information: 新西兰EPA化学品清单状态:2,5-二氯苯甲酸:没有单独批准但可在适当的团体标准下使用
- fire hazard: 该化学品的闪点数据不可用;但可能是可燃的。(NTP, 1992)
- fire fighting: 涉及此材料的火灾可以用干化学灭火器、二氧化碳或哈龙灭火器控制。(NTP, 1992)
- reactivity profile: 羧酸在有碱存在的情况下可提供氢离子。它们以这种方式与所有碱反应,包括有机碱(例如胺)和无机碱。它们与碱的反应称为"中和",伴随大量热量释放。酸和碱之间的中和反应产生水和盐。六个或更少碳原子的羧酸在水中的溶解度自由或中等;多于六个碳原子的羧酸在水中的溶解度较低。可溶性羧酸在水中一定程度解离产生氢离子。因此,羧酸溶液的pH值小于7.0。许多不溶性羧酸与含有化学碱的水溶液迅速反应并在中和过程中溶解...
- Air and water reaction: 不溶于水。
