Research on Production and Pyrophorisity of Iron Sulfur Compounds in Liquid Phase

Abstract:

The production and pyrophorisity of iron sulfur compounds in liquid phase were studied in order to get the spontaneous combustion rules of iron sulfur compounds producted by different ways. In the experiment, FeSO₄·7H₂O, FeCl₂·4H₂O, Fe (NO₃) ₃·9H₂O react with (NH₄)₂S_x and Na₂S·9H₂O respectively,then the pyrophorisity were analyzed by the exothermic oxidation process of sulfuration productions. The results show that, the pyrophorisity of sulfuration productions formed from (NH₄)₂S_x and dissolvable iron salt is obviously higher than formed from Na₂S and the same dissolvable iron salt. With the increase of dissolvable iron salt concentration, the oxidation pyrophorisity of sulfuration productions formed from (NH₄)₂S_x also increases. There is some pyrophorisity of sulfuration productions formed from Na₂S and dissolvable iron salt. But the pyrophorisity is faint relatively.
