| Abstract: | When double decomposition reaction of BaS and H_2SO_4 is induced to precipitate BaSO_4,(NH_2)_2CS and NaHS can be produced simultaneously by using the reaction product H_2S. This new technological process is superior to the traditional technology in that H_2S is made full use of to produce a series of sulphuric products with high additional value while pollution is reduced. |
