1. process for synthesizing potassium formate is characterized in that described technology may further comprise the steps:

  • (1) purify CO ↑

    , its purity is reached more than 90%;

    (2) choose the K that concentration is 3-5m (OH) solution, produce concentration with CO ↑

    synthetic and beThe synthetic liquid of 370-420g/L, operating pressure are 1-1.7Mpa, and synthesis temperature is 170℃

    -220 ℃

    ;

    (3) will synthesize the liquid sedimentation;

    (4) evaporation concentration is made the KCOOH liquid that requires density;

    Or (5) crystallization or film-making are dried to qualified industrial potassium formiate in product.
