Sodium sullide

Industrial uses for H-S include 111 die preparation of sullides. such as sodium sullide and sodium hydrosullide 12) the production of sulfur-bearing organic compounds, such as lliioplienes. mercaptans. and organic sullides (3) the removal of Cu. Cd. and Ti from spent catalysis where the gas acts as a precipitant (4) Ihe lormulation of extreme-pressure lubricants and (51 die preparation of rare-eardl phosphors used ill color TV lubes.

MOLECULE, hi the traditional sense, a molecule is the smallest particle of a chemical substance capable of independent existence with retention of all its chemical properties. Molecules comprise one or more atoms which need not be of the same kind. Only the rare, or noble gases form single-atom or monatomic molecules. All other elements form bi-. Iri. quudrt-. etc. atomic molecules, e.g.. hydrogen. H ozone. O-, phosphorus. P4 and sulfur, Sx or hydrogen chloride. IICI sodium sullide. Na S. aluminum chloride, AlClu carbon tetrachloride. C CI. and so on. 

Treatment of dinitro compounds of type (3) or (4) with sodium sullide in DMF under irradiation (20-W fluorescent light) produces olefins in high yield. Sodium thio-phenoxide in HMPT is also very effective.
