Abstract
Aqueous thiocarbonate solutions are synthesized in a batch or continuous reactor at a pressure below the critical pressure of carbon disulfide and at a temperature (at the pressure of the reaction) above the boiling point of carbon disulfide. The reactor is fitted with a condenser for preventing the escape of carbon disulfide vapor from the reaction zone. The batch synthesis procedure yields a product solution having a carbon-disulfide equivalent concentration of about 26 weight percent and takes about 62.5 minutes to complete (not including the time required to add the reactants to and remove the final product from the reactor).
