This compound is formed by the action of monochloracetic acid on a faintly alkaline solution of the 5-selenopyrazolone. It forms white needles, M.pt. 157° C., easily soluble in alcohol, hot benzene or aquoeus alkali, sparingly soluble in figroin, insoluble in water. 

Chromium pentaphenyl chloroacetate trihydrate, (C6H5)5 Cr(0.C0.CH2Cl)2H.3H20, from monochloracetic acid and the chromium base, forms hygroscopic, intensely red plates, M.pt. 103° C. The anhydrous salt is also known. The products dissolve readily in alcohol, pyridine or ethyl acetate. 

In the chemical industry chlorine is used for the production of various chemical compounds, such as hydrochloric acid, hypochlorites, chlorates, bleaching powder, aluminium chloride, corrosive sublimate, cupric chloride, carbon tetrachloride, tin recovery from used cans, sulphuryl chloride, for extraction of bromine from Stassfurt waste liquors, etc. In the organic chemical industry it is used for the chlorination of aliphatic and cyclic organic compounds, for the preparation of medicaments, the manufacture of plastics, insecticides, fungicides and herbicides.

Similarly, hydrogen chloride also escapes during chlorination of other hydrocarbons as well as in the manufacture of monochloracetic acid, chloral, etc. 

Monochloracetic Acid, according to Kolbe,1 is reduced to acetic acid, hydrochloric acid being split off at the same time free chlorine is evolved (Bunge 2). 

Acetic acid is used in the manufacture of a wide variety of products including adhesives, polyester fibres, plastics, paints, resins and solvents. About 40% of the acetic acid made industrially is used in the manufacture of vinyl acetate monomer for the plastics industry other large uses are to make cellulose acetate, a variety of acetate esters that are used as solvents, as well as monochloracetic acid, a pesticide. Acetic acid is also used as a solvent for the oxidation of p-xylene to terephthalic acid, a precursor to the important polyester, polyethylene terephthalate (PET). A minor, but important use is as non-brewed condiment, a vinegar substitute widely used in British fish and chip shops this is made using food-grade industrial acetic acid and is less expensive than fermentation vinegar.

The absence of analogy is still more striking between naphthalene and monochloracetic acid, whose mixtures have been studied by Cady. Within these mixtures there are formed two kinds of mixed crystals the first, rich in naphthalene, are isomorphous with pure naphthalene crystals the others, rich in monochloracetic acid, are isomorphous with those furnished by this acid taken by itself. 

Into a flask of about 200 ml. capacity fitted with a reflux condenser, 75 gm. monochloracetic acid, 45 gm. 95% alcohol and 10 gm. sulphuric acid (S.G. i-84) are introduced. These are stirred and heated on the water-bath at 100° C. for about 5-6 hours. At the end of the heating the mass is allowed to cool and then poured into a separatory funnel containing about 150 ml. cold water. The ethyl chloroacetate layer is separated, washed once more with water and then fractionally distilled. 

Tliis acid may be prepared in two ways (1) Sodium j3-aminophenyl-arsinate, 27 5 parts, is dissolved in 80 parts of hot water, a solution of 16 parts of monochloracetic acid in 20 parts of water added, and the whole heated under reflux for six to eight hours. The glycine derivative which crystallises on cooling is removed and washed with dilute hydrochloric add.
