Adduct having an acidic solution of sparingly-soluble group IIA complexes
An adduct that has an acidic solution of sparingly-soluble Group IIA complexes (“AGIIS”) and at least one additive. The AGIIS can be prepared by mixing a mineral acid (such as sulfuric acid), and a Group IIA hydroxide (such as calcium hydroxide) or a Group IIA salt of a dibasic acid (such as calcium sulfate), or a mixture of the two Group IIA compounds, followed by removing the solid formed. The additives can be an alcohol, an organic acid or a surface active agent. The composition has various uses, including cleaning, food production, decontamination, bioremediation, agricultural application, medical application, and detoxification of substances.
1. A composition comprising:
a solution or suspension of an acidic sparingly-soluble Group IIA complex (“AGIIS”); and
an additive, wherein the solution or suspension of the AGIIS is isolated from a mixture comprising sulfuric acid and calcium hydroxide, or calcium sulfate, or a mixture of the two, wherein the solution or suspension of the AGIIS contains from about 73,560 ppm to about 84,633 ppm of sulfate ions, and wherein when the solution or suspension of the AGIIS is isolated from a mixture comprising sulfuric acid and calcium hydroxide, for every mole of sulfuric acid used, the amount of total hydroxide ranges from about 0.1 mole to about 0.45 mole.
2. The composition of claim 1 , wherein the AGIIS has a certain acid normality that is less effective in charring sucrose and less corrosive to an animal skin than a saturated solution of calcium sulfate in sulfuric acid having the same acid normality, and wherein the solution or suspension of an AGIIS is non-volatile at room temperature and pressure.
3. The composition of claim 1 , wherein the additive comprises an alcohol.
4. The composition of claim 1 , wherein the additive comprises an organic acid.
5. The composition of claim 1 , wherein the additive comprises a surfactant.
6. The composition of claim 1 , wherein, based on the final weight of the composition, the amount of the solution or suspension of the AGIIS ranges from about 0.01% to about 99.99% of the composition, and the amount of the additive ranges from about 0.01% to about 99.99% of the composition.
7. A composition comprising:
a solution or suspension of an AGIIS prepared by mixing calcium hydroxide and sulfuric acid with or without the addition of calcium sulfate; and
an additive selected from the group consisting of an alcohol, an organic acid, a periodic acid, a surface active agent, and a mixture thereof, wherein the solution or suspension of an AGIIS contains from about 73,560 ppm to about 84,633 ppm of sulfate ions, and wherein when the solution or suspension of the AGIIS is prepared by mixing sulfuric acid and calcium hydroxide, for every mole of sulfuric acid used, the amount of total hydroxide ranges from about 0.1 mole to about 0.45 mole.
8. The composition of claim 7 , wherein the sulfuric acid contains a predetermined amount of calcium sulfate.
9. The composition of claim 7 , wherein the alcohol comprises a lower aliphatic alcohol having six or less carbon atoms.
10. The composition of claim 7 , wherein the organic acid is lactic acid, acetic acid, propionic acid, oxalic acid, per-acetic acid, or a mixture thereof.
11. The composition of claim 7 , wherein the surface active agent is cationic, anionic, non-ionic or a mixture thereof.
12. The composition of claim 7 , wherein the solution or suspension of the AGIIS has a certain acid normality that is less effective in charring sucrose and less corrosive to an animal skin than a saturated solution of calcium sulfate in sulfuric acid having the same acid normality, and wherein the solution or suspension of an AGIIS is non-volatile at room temperature and pressure.
13. The composition of claim 7 , wherein, based on the final weight of the composition, the amount of the solution or suspension of AGIIS ranges from about 0.01% to about 99.99% of the composition, and the amount of the additive ranges from about 0.01% to about 99.99% of the composition.
