Sodium Monochloro Acetate (SMCA)

SODIUM MONOCHLORO ACETATE (SMCA) (C2H2ClNaO2) is the sodium salt of Monochloroacetic Acid (MCA).
Sodium Monochloro Acetate (SMCA) is obtaining from neutralization of Monochloroacetic Acid (MCA) with Sodium Carbonate (Soda Ash).
Another method of manufacturing Sodium Monochloro Acetate (SMCA) is spraying molten Monochloroacetic Acid (MCA) together with 50 % Caustic Soda solution into a spray dryer.
