Abstract

A liquid deicer composition suitable for use as a deicer or as a pre-coat for solid deicers is disclosed. The composition typically includes molasses solids, magnesium chloride, and a corrosion inhibitor. In one implementation the liquid deicer composition includes molasses solids; magnesium chloride, and a corrosion inhibitor.

Claims

1. A deicer composition, the composition comprising on a water-free basis:

from 1.0 to 70 percent by weight molasses solids;

from 0.1 to 40 percent by weight magnesium chloride;

from 0 to 30 percent by weight of a corrosion inhibitor; and

sodium gluconate.

2. The deicer composition according to claim 1, wherein the composition comprises less than 45 percent by weight molasses solids.

3. The composition according to claim 1, wherein the composition comprises less than 25 percent magnesium chloride.

4. The composition according to claim 1, wherein the corrosion inhibitor is a phosphate salt.

5. The composition according to claim 4, wherein the phosphate salt is selected from the group consisting of orthophosphates, polyphosphates, pyrophosphates, organic phosphonates, and combinations thereof.

6. The composition according to claim 5, wherein the phosphate salt is selected from the group consisting of diammonium phosphate, monosodium phosphate, and calcium phosphate.

7. The deicer composition according to claim 1, wherein the corrosion inhibitor is triethanolamine.

8. The deicer composition according to claim 1, wherein the composition further comprises a solid deicer.

9. The deicer composition according to claim 8, wherein the solid deicer is selected from the group consisting of potassium chloride, magnesium chloride, sodium chloride, calcium chloride, urea, acetate salts, and combinations thereof.

10. The deicer composition according to claim 1, wherein the composition comprises greater than 0 and less than 10 percent sodium gluconate.

11. The deicer composition according to claim 1, wherein the composition comprises greater than 0 and less than 5 percent sodium gluconate.

12. The deicer composition according to claim 1, wherein the composition comprises from 0.5 to 1.5 percent sodium gluconate.

13. A deicer composition, the composition comprising on a water-free basis:

at least 0.5 percent by weight magnesium chloride;

at least 0.5 percent by weight molasses solids;

at least 80 percent by weight sodium chloride; and

less than 10 percent sodium gluconate.

14. The deicer composition of claim 13, wherein the composition comprises on a water-free basis:

0.5 to 13 percent by weight magnesium chloride;

0.5 to 3.0 percent by weight molasses solids; and

85 to 96 percent by weight sodium chloride.

15. The deicer composition of claim 13, wherein the deicer contains from 0.5 to 1.5 percent by weight monosodium phosphate.

16. The deicer composition of claim 13, wherein the deicer contains up to 2.0 percent by weight diammonium phosphate.

17. A deicer composition, the composition comprising:

a) one or more phosphate salts;

b) molasses solids;

c) chloride salt other than sodium chloride; and

d) sodium chloride.

18. The deicer composition of claim 17, wherein the composition based upon water-free weight comprises:

at least 0.5 percent by weight phosphate salt;

at least 0.5 percent by weight molasses solids;

at least 2.0 percent by weight magnesium chloride; and

at least 70 percent by weight sodium chloride.

19. The deicer composition of claim 18, wherein the phosphate salt comprises monosodium phosphate.

20. The deicer composition of claim 18, wherein the phosphate salt comprises diammonium phosphate.

21. The deicer composition of claim 17, wherein the composition based upon water-free weight comprises:

0.5 to 2.0 percent by weight of a phosphate salt;

0.5 to 2.0 percent by weight molasses solids;

2.0 to 6.0 percent by weight magnesium chloride and

80 to 97 percent by weight sodium chloride.
