Abstract
Aromatic stibinic acids are prepared by treating a diazo compound with antimony oxide in the presence of a polyvalent alcohol such as glycerin or mannite. The product is not very soluble in the alkaline solution containing the polyvalent alcohol and readily precipitates with acid; the presence of the alcohol also reduces the amount of undesirable by-products. According to the examples, (1) a solution of antimony oxide in hydrochloric acid, to which glycerin has been added, is poured into an ice-cooled solution of diazotized aniline and caustic soda then added; the resulting phenylstibinic acid is precipitated with hydrochloric acid and purified, when a greater yield is obtained than if glycerin were absent or if tartar emetic were used instead of antimony oxide; (2) similar increase in output is obtained if glycerin be added when making p-chlorophenylstibinic acid, or m-chloro-p-acetylaminophenylstibinic acid from 2-chloro-4-amino-1-acetanilide.
