Study of the intereaction of sodium tyocyanate with the mineral acids and investigation of the properties of received products

Hydrogen sulfide gases are formed in many technological processes, in particular, the processing of natural combustible fossil fuels. During the purification of coke oven gas containing cyanadium, from hydrogen sulfide by arsenic-sodic method, sodium thiocyanate is formed together with thiosulfate. Polymer sulfur, which is formed because of the acid decomposition of sodium thiosulfate, contains slightly soluble impurities. They aggravate its rheological properties and cause excessive high ash content of polymer sulfur up to 8%.
