벤젠알소닉 산 C화학적 특성, 용도, 생산
화학적 성질
white to slightly yellow crystalline powder용도
Arsonic acids (arsonic acid, phenylarsonic acid, p-hydroxyphenylarsonic acid, arsanilic acid) react with the tetravalent metals of group IV of the periodic system to give water-insoluble complexes of composition MA2 . The composition of the precipitates is not exactly stoichiometric, and hence the precipitates are not suitable for direct gravimetric analysis. Instead, the precipitates are transformed by ignition to the corresponding metal oxides and weighed as such. The main advantage of the application of these reagents is the possibility offered of the selective determination of zirconium(IV), hafnium(IV) and titanium(IV) in the presence of many other metals, such as zinc, manganese, nickel, cobalt, aluminium, copper, calcium, magnesium and chromium. In practice they are utilized most frequently for the determination of zirconium.In strong mineral acidic media phenylarsonic acid forms water-insoluble precipitates with zirconium and hafnium only. In highly concentrated acetic acid solution the thorium phenylarsonate complex is also precipitated, which makes possible the separation of thorium from rare earth metals.
The procedure gives satisfactory results in the presence of alkaline earth metals, iron, aluminium, manganese, cobalt, nickel, copper, zinc and bismuth.

UN3280 Organoarsenic compound, liquid, n.o.s., Hazard Class: 6.1; Labels: 6.1—Poisonous materials, Technical Name Required. Potential Inhalation Hazard (Special Provision 5).Purification Methods
Crystallise it from H2O (3mL/g) between 90o and 0o. Alternatively dissolve 600g of the acid in 500mL of boiling H2O, add 20g of Norite, filter hot, cool, filter off the crystals and dry them. On heating at ~154-160o it is converted to the anhydride.
