Abstract
The following sulphides were precipitated with hydrogen sulphide from solutions of naphthenates in organic solvents: In2S3, CoS, NiS, CuS, ZnS, CdS, HgS, PbS, Ag2S and the thiospinels NiIn2S4, CdIn2S4 and HgIn2S4. Not precipitated are chromium (II) and chromium (III). The ir-spectra of the naphthenates are discussed.
