FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for preparing concentrates of γ-ketosulfides. Method for preparing concentrates of γ-ketosulfides is based on the alkylthiomethylation reaction of ketones with a mixture of formaldehyde and methane gas odorant containing mercaptanes and disulfides in an aqueous-alkaline medium at temperature 20 ± 5°C. Proposed method provides enhancing the yield of the end product. Concentrates of γ-ketosulfides can be used as foaming agents-collecting agents in flotation of copper-zinc and gold-containing ores or adsorbents of sulfur dioxide.
EFFECT: improved preparing method, valuable properties of concentrates.
