Nowadays, for industrial sulfur and various sulfur powder and sulfur block products, they are all made of sulfur. Sulfur itself is unstable from a chemical analysis alone. Improving the stability of sulfur is necessary if sulfur is to be used efficiently to make products.
To correctly improve the stability of industrial sulfur, halogens and their derivatives can be used as insoluble sulfur stabilizers, such as iodine, bromine, ferric chloride, titanium tetrachloride, phosphorus tetrachloride, phosphorus pentachloride, tetrachloride Silicon chloride, sulfur monochloride, sulfur dichloride and phosphorus oxychloride, etc., as well as dilute acids, hydrogen sulfide, sulfides, hydrocarbon oils, olefins, terpenes, some acid-base systems, etc. Halogen atoms, hydrogen atoms, etc. in the stabilizer form bonds with the sulfur atoms at both ends to stabilize the insoluble sulfur.
Of course, if industrial sulfur is exposed to sunlight for a long time in the field environment, under the action of ultraviolet radiation, high temperature, microorganisms and oxygen, the insoluble sulfur will disintegrate and be reduced to soluble low molecular orthorhombic sulfur, and gradually oxidized to Sulfur dioxide becomes sulfurous acid after absorbing water, and can be converted into sulfuric acid if further oxidized. Even insoluble sulfur treated with chemical stabilizers will still undergo obvious reduction under long-term storage conditions, under the action of heat above 105 °C close to the melting point, or under the induction of alkaline substances, especially amines. In short, by taking the correct method to improve the stability of sulfur powder, the quality of the sulfur powder products made in this way will be effectively improved, and after reprocessing by the manufacturer, it can play an important role in all walks of life.
