The said treatment process can eliminate the effect of the impurity and produce sodiumhydrosulfide product similar to that produced through barium salt process.
In order to reduce raw material costs, this topic then studied at the condition of atmospheric pressure taking hydrosulfidesodium as materials to synthesis sodium thioglycolate kettle-style process.
