Phenylarsonic acid is a chemical compound selected from the group consisting of arsenic acid derivatives in which a hydroxy group has been replaced by a phenyl group.

Production and representation

Phenylarsonic acid can be synthesized in several ways, but is usually prepared by reacting with sodium arsenite Phenyldiazoniumsalzen in the presence of copper ( II) catalysts.

It was first produced by Michaelis and Loenser.

Properties

Phenylarsonic acid is a flammable white odorless solid that is slightly soluble in water. It decomposes above 158 ° C.

Use

Phenylarsonic acid is used as a starting material for other arsenic- organic compounds, some of which are used, for instance roxarsone and Natriumhydrogenarsanilat in animal nutrition.

It is also used as precipitation reagent for tetravalent metal ions such as tin ( IV), zirconium (IV), and thorium ( IV).
