66℃)、C4H8O2I2(m.p. 84℃)、C4H8O2Cl2，与硫酸形成C4H8O2H2SO4(m.p. 101℃)等氧化合物。与氯化锂或三氟化硼也能形成络合物LiCl·C4H8O2·H2O，BF3·2H2O·C4H8O2。在钯、铑、镍等金属催化下，二噁烷在重氢和醚间进行同位素交换。二噁烷与四硝基甲烷反应呈鲜黄色，此反应可用来检验二噁烷。\n3.属微毒类。毒性比乙醚强2~3倍。中毒时最初出现麻醉、呕吐，尿频后尿减少，终至停止排尿。同时血液中尿素增加，嗜眠，昏睡，2~3日后死亡。长期接触或吸入其蒸气时，刺激眼、鼻、咽喉和肺，损害肝、肾、脑和皮肤。工作场所最高容许浓度360mg\u002Fm3，超过720mg\u002Fm3时即能引起头痛和胃痛等症状。二噁烷能经皮肤吸收而中毒，接触皮肤时应用大量水冲洗和用肥皂洗净。\n4.稳定性

\n\u003Cbr \u002F>废弃物处置方法：不含过氧化物的废料液经浓缩后，控制一定的速度燃烧。含过氧化物的废料经浓缩后，在安全距离外敞口燃烧。 \n\u003Cbr \u002F>\n\u003Cbr \u002F>二、防护措施 \n\u003Cbr \u002F>\n\u003Cbr \u002F>呼吸系统防护：可能接触其蒸气时，佩戴自吸过滤式防毒面具(半面罩)。 \n\u003Cbr \u002F>眼睛防护：戴化学安全防护眼镜。 \n\u003Cbr \u002F>身体防护：穿防静电工作服。 \n\u003Cbr \u002F>手防护：戴橡胶手套。 \n\u003Cbr \u002F>其它：工作现场严禁吸烟。工作毕，淋浴更衣。注意个人清洁卫生。 \n\u003Cbr \u002F>\n\u003Cbr \u002F>三、急救措施 \n\u003Cbr \u002F>\n\u003Cbr \u002F>皮肤接触：脱去被污染的衣着，用肥皂水和清水彻底冲洗皮肤。 \n\u003Cbr \u002F>眼睛接触：提起眼睑，用流动清水或生理盐水冲洗。就医。 \n\u003Cbr \u002F>吸入：迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难，给输氧。如呼吸停止，立即进行人工呼吸。就医。 \n\u003Cbr \u002F>食入：饮足量温水，催吐，就医。 \n\u003Cbr \u002F>\n\u003Cbr \u002F>灭火方法：尽可能将容器从火场移至空旷处。喷水保持火场容器冷却，直至灭火结束。处在火场中的容器若已变色或从安全泄压装置中产生声音，必须马上撤离。灭火剂：抗溶性泡沫、干粉、二氧化碳、砂土。用水灭火无效。 \n\u003Cbr \u002F>\u003Cbr
