The most common production method for dichloroacetic acid is the hydrolysis of dichloroacetyl chloride, which is produced by the oxidation of trichloroethylene. It can also be obtained by hydrolysis of pentachloroethane with 88–99% sulfuric acid or by oxidation of 1,1-dichloroacetone with nitric acid and air.

What is dichloroacetic acid used for?

Dichloroacetic acid is used as a chemical intermediate in the synthesis of organic materials, as an ingredient in pharmaceuticals and medicines, as a topical astringent, and as a fungicide (Hawley, 1981; HSDB, 2001).

Is dichloroacetic acid harmful?

* Dichloroacetic Acid is a HIGHLY CORROSIVE CHEMICAL and contact can cause severe skin and eye irritation and burns with possible permanent eye damage. * Breathing Dichloroacetic Acid can irritate the nose and throat. * Breathing Dichloroacetic Acid can irritate the lungs causing coughing and/or shortness of breath.

What is dichloroacetic acid in water?

Dichloroacetic acid, one of the group of five haloacetic acids regulated by federal standards, is formed when chlorine or other disinfectants are used to treat drinking water. Haloacetic acids and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy.

How is dichloroacetic acid removed from water?

While the best way to remove the contamination from your drinking water is by eliminating the source of the pollutant, a solid carbon block water filter systems can help remove Dichloroacetic Acid to below the EPA's contamination level standards.

What are the side effects of DCA?

DCA was discovered to be a safe drug with no cardiac, pulmonary, renal or bone marrow toxicity[4]. The most serious common side effect consists of peripheral neuropathy, which is reversible[6]. Delirium has been reported, and is reversible after discontinuation of DCA[7].

What is DCA metabolism?

DICHLOROACETATE (DCA)

Dichloroacetate (DCA) is a metabolic modulator that inhibits mitochondrial pyruvate dehydrogenase kinase and increases mitochondrial oxidative phosphorylation. DCA also depolarizes the mitochondria, causing release of H2O2 and cytochrome c.

Is dichloroacetic acid a strong acid?

As an acid with a pKa of 1.35, pure dichloroacetic acid is classed as a strong organic acid; it is very corrosive and extremely destructive to tissues of the mucous membranes and upper respiratory tract via inhalation.


What is haloacetic acids in drinking water?

Haloacetic acids (HAA) are a group of disinfection byproducts that form when chlorine compounds that are used to disinfect water react with other naturally-occurring chemicals in the water.

What is the pKa of acetic acid?

For example, the Ka constant for acetic acid (CH3COOH) is 0.0000158 (= 10-4.8), but the pKa constant is 4.8, which is a simpler expression. In addition, the smaller the pKa value, the stronger the acid.

Is Dichloroacetate FDA approved?

US Food and Drug Administration Approval

There is not enough evidence that dichloroacetate is effective in the fight against cancer, and it has not been approved by the FDA for cancer treatment.

What is fenbendazole used for?

Fenbendazole is widely used as an antiparasitic agent against various gastrointestinal parasites, such as pinworms, giardia, roundworms, hookworms, Taenia solium, and pulmonary paragonimiasis [6-13]. The agent is used in several animal species, that is, dogs, cats, rabbits, rats, horses, sheep, and cattle [6-15].


What is DCA medical?

DCA, or directional coronary atherectomy is a minimally invasive procedure to remove blockage from coronary arteries to improve blood flow to the heart muscle and ease pain. ... This new wire is used to insert a diagnostic catheter, a long flexible tube, into the artery and guide it to the heart.

What is Ka value of an acid?

The acid dissociation constant (Ka) is used to distinguish strong acids from weak acids. ... The Ka value is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates. Thus, strong acids must dissociate more in water.

Is formic acid a strong acid?

Figure 1 Formic acid (methanoic acid, HCOOH) is a weak acid that occurs naturally in bee and ant stings. Formic acid makes up 55–60% of the body mass of a typical ant; its name comes from 'formica', the Latin word for ant.

Is citric acid a weak or strong acid?

Citric acid is a weak organic acid. It occurs naturally in produce, and in particular, citrus fruits such as limes, oranges, and lemons. Citric acid is a naturally occurring antioxidant. People use it as a food flavoring and preservative, an ingredient in cosmetics, and a component in cleaning products.


Which is the strongest acid?

The strongest acid is perchloric acid on the left, and the weakest is hypochlorous acid on the far right. Notice that the only difference between these acids is the number of oxygens bonded to chlorine. As the number of oxygens increases, so does the acid strength; again, this has to do with electronegativity.

Is trichloroacetic acid stronger than HCL?

carboxylic acids

(The NO2 group is a very strong electron-withdrawing group.) An even greater effect is found in trichloroacetic acid, Cl3CCOOH, whose acid strength is about the same as that of hydrochloric acid.

Is Chloroethanoic acid weak or strong?

Similarly, chloroacetic acid, ClCH2 COOH, in which the strongly electron-withdrawing chlorine replaces a hydrogen atom, is about 100 times stronger as an acid than acetic acid, and nitroacetic acid, NO2CH2 COOH, is even stronger.
