在空气中,砷化氢以气体状态存在,它具有大蒜气味,对空气的比重为2.695,微溶于水。金属中常含有微量砷,当酸和金属反应生成氢气常伴有砷化氢产生。此外象含砷的金属炉渣、矽铁、电石等遇到水份也会产生一些砷化氢。
In the air, arsine exists as a gas, has a garlic odor and has a specific gravity of 2.695 for air, slightly soluble in water. Metal often contains traces of arsenic, when the reaction of acid and metal to produce hydrogen is often accompanied by arsine. In addition, like arsenic-containing metal slag, ferrosilicon, calcium carbide encountered in water will also produce some arsine.
