Crystalline sodium sulfide is produced only by Sankyo Kasei in the world.Compared with flake type, it has less iron content and is effective for iron-unfriendly reactions in organic synthesis.

Chemical name

Crystal Sodium Sulfide

Application

Raw material for PPS resin, organic synthetic chemistry, leather depilatory agent, auxiliary agent for sulfide dyeing and copper mine flotation beneficiation.

Example of use

Strong alkalinity, strong hygroscopicity, soluble in water, oxidized by air to form sodium thiosulfate. Reacts with acids to produce hydrogen sulfide gas and produces sulfurous acid gas when burned.

Product Form
