Chloroacetic acid is also used in the production of phenoxy herbicides by etherification with chlorophenols. In this way 2-methyl-4-chlorophenoxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid, and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) are produced. It is the precursor to the herbicide glyphosate and dimethoate.
Chloroacetic acid is chemical intermediate for production of various pharmaceuticals and insecticides. Trichloroacetic acid is used for various analytic tests in biochemistry. In sufficient concentration it will cause protein, DNA and RNA to precipitate out of solution. The sodium salt of trichloroacetic acid is used as a weedkiller.
Trichloroacetic acid (TCA; TCAA; also known as trichloroethanoic acid) is an analogue of acetic acid in which the three hydrogen atoms of the methyl group have all been replaced by chlorine atoms. Salts and esters of trichloroacetic acid are called trichloroacetates .
Dichloroacetic acid (DCA), sometimes called bichloroacetic acid (BCA), is the organic compound with formula CHCl 2 CO 2 H. It is an analogue of acetic acid, in which 2 of the 3 hydrogen atoms of the methyl group have been replaced by chlorine atoms. Like the other chloroacetic acids, it has various practical applications.
It is a precursor to thioglycolic acid by reaction with sodium hydrosulfide. Reaction with cyanide salts gives cyanoacetate NCCH 2 CO 2 Na. [3] Cyanoacetate is a precursor to malonic acid. Sodium chloroacetate is a common laboratory reagent in organic chemistry as illustrated by many entries in the book series Organic Syntheses. With ...
Ether synthesis by reaction of salicylaldehyde with chloroacetic acid and sodium hydroxide [1] The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol . This reaction was developed by Alexander Williamson in 1850. [2]
Carboxymethyl cellulose is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. [3] The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. [4] Fabrics made of cellulose – e.g., cotton or viscose (rayon) – may also be converted into CMC. [5]
The two main processes are amination of chloroacetic acid with ammonia, giving glycine and hydrochloric acid, [24] and the Strecker amino acid synthesis, [25] which is the main synthetic method in the United States and Japan. [26] About 15 thousand tonnes are produced annually in this way. [27]
