Sodium Sulfide properties uses production
Sodium sulfide is also a chemical substance. Its properties are strongly alkaline, yellow or reddish in color, and it is lumpy or granular. It is easily soluble in water, and when dissolved, it often generates heat and has the smell of hydrogen sulfide escaping.
As for its use, it is quite extensive. In the papermaking industry, it can be used as a cooking aid to help the fiber separate and make the pulp better texture. In the process of leather tanning, it can remove hair and degrease, making leather soft and durable. It is also used in the dye industry. It is an important raw material for the synthesis of various dyes, which helps the color of dyes to be distinct.
There are several common methods of production. First, sodium sulfate and carbon are heated together to produce sodium sulfide through chemical reaction. In the reaction, charcoal is used as a reducing agent to promote the reduction of sulfur in sodium sulfate. Second, it is obtained from the reaction of barium sulfide and sodium carbonate solution. This process requires precise temperature control and control of the reaction conditions to obtain high-purity sodium sulfide.
All these are the characteristics, uses and production of sodium sulfide.
