1. THE METHOD OF PREPARING THIOCARBONATES WHICH COMPRISES REACTIG CARBON WITH AN INORGANIC SULFIDE OF A MEMBER OF THE GROUP CONSISTING OF AMMONIUM, ALKALI METALS, AND ALKALINE EARTH METALS, IN A LIQUID MEDIUM COMPRISING FROM 97 TO 70 PERCENT BY WEIGHT OF AN INET ORGANIC LIQUID DILUENT SELECTED FROM THE GROUP CON-K SISTING OF ALIPHATIC PARAFFIN, CYCLOPARAFFIN, AROMATIC AND HALOGENATED ALIPHATIC HYDROCARBONS HAVING BOILING POINTS IN THE RANGE OF 30 TO 100*C., AND FROM 3 TO 30 PERCENT BY WEIGHT OF LEVELLING SOLVENT SELECTED FROM THE GROUP CONSISTING OF METHANOL, ETHANOL, ISOPROPANOL, DIOXANE AND DIMETHYLFORMAMIDE, AND LEVELLING SOLVENT BEING CHARACTERIZED BY A MEASURABLE SOLVENCY FOR SAID INORGANIC SULFIDE AND BEING FURTHER CHARACTERIZED BY A SUBSTANTIAL MISCIBILITY WITH SAID INERT ORGANIC LIQUID DILUENT.
