Abstract
FIELD: inorganic chemistry, chemical technology. SUBSTANCE: method involves effect of basic dissolving agents on sulfur. Mixture hydrazine-hydrate-alkali at mole ratio 1:(0.05-0.5) is used as a solvent of elemental sulfur. Sulfur dissolving begins at room temperature and occurs effectively at reaction mass heating to 80-90 C. Dissolving is carried out at environment medium temperature. Sodium or potassium hydroxide is used as alkali. At dilution with water prepared solvents eliminate sulfur rapidly and without large losses and sulfur can be filtered off and utilized. Method is based on self-heating phenomena. EFFECT: increased effectiveness of process. 2 cl
