第四十八类非金属氢化物活性特点:非金属氢化物具有EHn活性基团,大多数挥发性氢化物的最低爆炸氧浓度几乎是零。因此,在处理非金属氢化物时,全部除掉空气或氧气对安全操作是重要的。在氢化混合物中有杂质时会更进一步增加着火的危险。值得强调的是:硫化氢不仅与空气混合能形成爆炸性混合物,而遇明火、高热且能引起燃烧或爆炸。若遇高热,容器内压增大,有爆炸的危险。同时它还是属高毒类危险品,是强烈的神经毒物,对粘膜有强烈的刺激作用。
The forty-eighth category non-metallic hydride activity characteristics: non-metallic hydrides have EHn active groups, most of the lowest volatile oxygen concentration of volatile oxygen is almost zero. Therefore, in the treatment of non-metallic hydride, the total removal of air or oxygen is important for safe operation. There is a further risk of fire when impurities are present in the hydrogenation mixture. It is worth emphasizing that not only is hydrogen sulfide mixed with air to form an explosive mixture, but also exposed to fire, heat and can cause combustion or explosion. In case of high fever, the container pressure increases, there is the danger of explosion. At the same time it is still a high-toxic dangerous goods, is a strong nerve poison, a strong stimulating effect on the mucous membrane.
