Abstract: ALKALI METAL FORMATE IS MADE FROM ALKALI METAL THIOSULFATE BY THE FOLLOWING THREE STEPS:

(1) REDUCTION: 4MCOOH+M2S2O3+H2O=4MHCO3+2MSH

(2) STRIPPING:D

MHCO3+MSH=M2CHO3+H2S CO2+H2O+MSH=MHCO3+H2S

(3) FORMATE SYNTHESIS:

M2CO3+2CO+H2O= 2MCOOH+CO2 M2CO3+CO+H2=2MCOOH

WHERE M IS EITHER SODIUM OR POTASSIUM. THE FOREGOING PROCESS IS USEFUL IN CONNECTION WITH THE ABSORPTION OF SULFUR DIOXIDE FROM FLUE GAS BY ALKALI METAL FORMATE AT TEMPERATURES ABOVE 140*F. TO FORM THE CORRESPONDING THIOSULFATE.

Abstract: SODIUM, POTASSIUM, OR AMMONIUM THIOSULFATE IS CONVERTED IN ONE STAGE TO THE CORRESPONDING FORMATE AND H2S BY HEATING THE THIOSULFATE TO AN ELEVATED TEMPERATURE ABOVE 475*F. IN THE PRESENCE OF CARBON MONOXIDE, STEAM,AND

ONE OF THE FOLLOWING: SODIUM, POTASSIUM, AND AMMONIUM FORMATES.
