G. Taddei7 prepared potassium iodide by adding a dil. soln. of potassium monosulphide to an alcoholic soln. of iodine. In place pf potassium sulphide, J. von Liebig and C. Wittstock used barium sulphide, prepared by calcining sulphate with coke. According to R. Schindler, the products obtained by the sulphide process are contaminated with sulphur compounds. G. S. Serullas treated potassium antimoniate (prepared by calcining tartar emetic) with an alcoholic soln. of iodine as long as the soln. was decolorized. The filtered soln. was evaporated to the point of crystallization. 

Diluted Standard Solution Pipet 2.00 mL of Stock Standard Solution into a 100-mL volumetric flask, dilute to volume with 6 N hydrochloric acid, and mix. Each milliliter contains 20 pig of antimony. Prepare this solution fresh weekly. 

Several other metals have been used in this Barbier-type reaction. Thus, a mixture of bismuth(III) chloride/aluminum [160] or of bismuth(III)chloride/ magnesium [161] was shown to promote allylation of aldehydes under aqueous conditions yielding homoallylic alcohols in good yields. Similarly, the same reaction can be promoted with metallic lead [162], highly reactive antimony prepared by the NaBH4 reduction of SbClj [163] or a mixture of manganese and catalytic copper [164]. In the latter case, aromatic aldehydes reacted whereas ali-...

Antimonial preparations have alfo been of late much ufcd with great advantage as diaphoretics. / For the hiflory and ufe of thefe preparations I fhall refer the reader to the late writers on the Materia Medica, only obfervliig that the ftomach becomes fo foon habituated to its flimulus, that the fecond dofe may be confiderably increafed, if the firft had no operation. ... 

A solution of SbCU (d 1.265) is reduced with Zn dust. The resultant Sb is washed several times with O.IN HCl until free of Zn, then treated with alcohol and ether, and finally dried in a stream of CO 3. Antimony prepared by other methods does not reduce TiCU as efficiently. 

The Epsom salt sold on the Continent and extracted from salt brine was very impure. Chaptal pointed out that many antimonial preparations used in medicine are dangerous because of the varying antimony content, and recommended inspection to check fraudulent manufacture. The fuming liquor of Libavius (SnCl4) is a muriate of tin, in which the acid is in the state of the oxigenated muriatic acid . ...

According to the Colour Index (Cl 77050), this is precipitated metallic antimony, prepared by treating an acid solution of an antimony salt to precipitate a fine black powder known as antimony black or iron black. It is said to be used to impart the appearance of polished steel to papier mach6 and plaster of Paris . Terry (1893) lists iron black as grormd black sulphide of iron . See also iron oxide black.
