·Property formula：SF4 Molecular weight：**8.*5 GB ID：****9 CAS number：********0 Risk category： 2.3 Class Toxic Gas Chemistry Class：Halogens and halogen compounds Physical and chemical properties Melting（oC）：***1.0 Boiling（oC）：**8 Density：Density（water = 1）1.*5（liquid），2.*5（solid）； density（air =1）3.7 Critical temperature（oC）：*0.9 Critical pressure：***2.9kPa Solubility：Soluble in benzene Stability：Stable Transportation information Risk number：****9 NO.：***8 Package class：Ⅱ Package mark：6 Package ：Steel cylinder Transportation：by bus、by train、by ship , by air Product description SF4 is familiar with SO2, in normal temperature and press; it is a kind of colorless toxic gas with strong Irritating odor. it can’t be fire in air .it is stable when the temperature is below **0oC, but when it occurs with Moist air , it will be hydrolyzed and produce Toxic fumes which has strong toxic just like Phosgene. When SF4 reacts strongly with water and acid will produce hydrogen fluoride and sulfur dioxide. When has a little water, it will rust Glass.SF4 can soluble in benzene and it is widely used as fluorinating agent.
