Abstract
p-Oxy-m-nitrophenylarsinic acid is prepared by nitrating and diazotizing arsanilic acid in the same solution. The nitration may be simultaneous with or subsequent to the diazotization. Preferably nitric acid is used in sufficient quantity both to effect nitration and to liberate nitrous acid from the nitrite used for diazotization, but any other acid may be employed for the latter purpose. The product may be purified by conversion into a salt and recovery of the acid therefrom. According to the examples, (1) sodium nitrite is added to a mixture of arsanilic acid and nitric acid; after standing a short time, the whole is heated and then allowed to cool for separation of the product; (2) arsanilic acid is first diazotized and nitric acid then added to the solution; the mass is heated for some time or allowed to stand for several weeks; the product separates out as a crystalline mass. Examples are also given of the purification of the product by first forming the sodium or potassium salt, followed if desired by conversion into the calcium salt, and then decomposing the salt to free the pure acid. A purity test for the product using sodium hydrosulphite is described.
