毒理学数据：

1.试验方法：吸入
摄入剂量： 10 mg/m3/4H
测试对象：啮齿动物-鼠
毒性类型：急性
毒性作用： (1)肺 ，胸部或呼吸-咳嗽

2.试验方法：吸入
摄入剂量： 2 mg/m3/30M/26W-I
测试对象：哺乳动物-物种不详
毒性类型： MutipleDose
毒性作用： (1)心电图变化不影响诊断的指定
                      (2)肝功能受损
                      (3)体重减轻或减少体重增加。

3.在潮湿空气中能自燃。加热或接触水或酸类能发生放热反应，也能引起燃烧。能与氧化剂剧烈反应，密集的粉尘遇热或氧化剂接触即行爆炸。粉尘对眼睛、鼻、皮肤和呼吸系统有强刺激作用。遇湿气或水分生成氢氧化锂腐蚀性很强。

4.急性毒性^[7]  LD50：77.5mg/kg（大鼠经口）

5.刺激性^[8]  家兔经眼：5mg/m³，引起刺激。
