【理化性状和用途】
无色透明液体, 有类似苯的芳香气。熔点为-94.9℃，沸点为110.6℃。不溶于水，可混溶于苯、醇、醚等多数有机溶剂。主要用于掺合汽油组成及作为生产甲苯衍生物、****、染料中间体、药物等的主要原料。
【毒性及燃爆性】
属低毒类。对皮肤、粘膜有刺激作用, 对中枢神经系统有麻醉作用, 长期作用可影响肝、肾功能。急性中毒：病人有咳嗽、流泪、结膜充血等; 重症者有幻觉, 神志不清等, 有的有癔病样发作。慢性中毒：病人有神经衰弱综合症的表现, 女工有月经异常, 工人常发生皮肤干燥、皲裂、皮炎。
本品易燃，爆炸限为1.2～7.0%，其蒸气与空气形成爆炸性混合物, 遇明火、高热能引起燃烧爆炸, 与氧化剂能发生强烈反应, 其蒸气比空气重, 能在较低处扩散到相当远的地方, 遇明火源引着回燃. 若遇高热, 容器内压力增大, 有开裂和爆炸的危险。
