Chloroethanoic acid

It is an important dyestuffs intermediate. It condenses with chloroethanoic acid to give phenylglycine-o-carboxylic acid for the synthesis of indigo. It can be diazotized and used as a first component in azo-dyes it condenses also with chloroanthraquinones to give intermediates for anthraquinone dyes. [Pg.36]

CCls CHO. A colourless oily liquid with a pungent odour b.p. 98°C. Manut actured by the action of chlorine on ethanol it is also made by the chlorination of ethanal. When allowed to stand, it changes slowly to a white solid. Addition compounds are formed with water see chloral hydrate), ammonia, sodium hydrogen sulphite, alcohols, and some amines and amides. Oxidized by nitric acid to tri-chloroethanoic acid. Decomposed by alkalis to chloroform and a methanoate a convenient method of obtaining pure CHCI3. It is used for the manufacture of DDT. It is also used as a hypnotic. [Pg.91]

MCPA, l-methyl-A-chlorophenoxyacetic acid, Methoxone, CgH ClOj. Made by chlorination of o-cresol followed by reaction with chloroethanoic acid. While crystals, m.p. 118-119 C. As usually obtained, crude MCPA contains both 4- (60%) and 6- (40%) chloro-isomers, and is a light brown solid. Selective weedkiller. [Pg.252]

Prepared by the action of chloroethanoic acid upon anthranilic acid. It can also be prepared by the action of KCN and methanal on anthranilic acid, followed by hydrolysis with NaOH of the nitrile of anthranilic acid first produced. [Pg.305]

Structures 16, 2 (R -R = Me), ° 4, if and 137, are all converted to the corresponding hydantoins by aqueous or methanolic hydrochloric acid, but it is possible to achieve selective hydrolysis. Thus, with aqueous ethanoic acid, 4 yields 148 (64%), whereas methanolic chloroethanoic acid cleaves 115 to 149(86%) the salt 137 gives 150 in aqueous methanol. ° ... [Pg.445]

Exercise 18-7 Fluoroethanoic acid is only about twice as acidic as chloroethanoic acid, even though fluorine is much more electronegative than chlorine (Section 10-4B). The lengths of aliphatic C-F bonds are about 1.38 A, whereas those of C-CI bonds are 1.78 A How could this difference in bond lengths tend to compensate for the differences in electronegativity between chlorine and fluorine and make the acids similar in strength ... [Pg.801]

Explain why the mono-, di- and tri-chloroethanoic acids are progressively stronger acids than the original ethanoic acid. You should consider the inductive effect of the chloro group (electron attracting) on the 0-H bond. [Pg.362]

Monochloroacetic acid (Figure 12.3), also known as chloroacetic acid and chloroethanoic acid, which has a molecular weight of 94.5, can be obtained from the reaction between acetic acid and chlorine under high pressure. The pH of an 80% MCA solution is lower than 1 and its pK, is 2.82. [Pg.79]

SYNONYMS Alpha chloroacetic acid, chloroethanoic acid, monochloroacetic acid, monochloroethanoic acid. [Pg.46]

The Cl— -CH2C00 ion is more stable than CHjCOO", so for chloroethanoic acid is much greater than that for ethanoic acid. Additional electron-withdrawing groups increase this effect, but the influence of the electron-withdrawing group on acid strength falls off with distance. [Pg.339]

In addition, modified phenol methanal polymers of phenoxy ethanoic acids are useful as crosslinldng agents for epoxy resins. The monomer is formed by reacting 2-chloroethanoic acid with a phenol to give the corresponding jiienoxy ethanoic acid. [Pg.641]
