ABSTRACT:
A deicing product comprising a mixture having, based upon the total weight of solid in said deicing product between 12% and 75% acetate salts, trace amounts and 36% carbonate salts, 1 and 24% formate salts, 1 and 32% pseudolactate salts. The cations of said salts are selected from the class consisting of sodium, magnesium, calcium, potassium. Lignin fractions and low molecular weight sugars may also be present, as well as other chemicals derived from the method of making black liquor and this new product. A method of making same is disclosed. It comprises using a black liquor obtained from a pulp mill operation, fractionating said black liquor into a low molecular weight fraction, concentrating said collected low molecular weight fraction to produce a concentrated deicing product.
