Antimony oxychloride, preparation

To prepare antimony oxychloride, 50g of antimony trichloride (No. 77) are stirred well with 35ml of water and allowed to stand for 2-3 days. The white product is filtered off, washed with 50ml of 95% alcohol and with the same volume of ether. The material is dried at 100°C. 

To a solution of SbCl, (15 g, 50 mmol) in CCI4 (50 mL) was added dropwise a solution of norborna-2,5-diene (9.2 g, 100 mmol) in CCI4, (150 mL) at 25 °C and the resulting clear solution was stirred for 10 min. HjO was added to this solution and the precipitated antimony oxychloride was filtered. Then the organic layer was distilled to give the products yields 6.5 g (80%) bp 95-96°C/22 Torr. This 58 42 mixture of stereoisomers 11 and 12 was separated by preparative GC.

The oxytriiodide, PaOIs, and dioxymonoiodide, PaOgl, have both been prepared (40) by reacting the pentaiodide with the stoichiometric amount of antimony sesquioxide [Eqs. (9) and (10)]. PaOIs, a dark brown solid, is thermally unstable [Eq. (11)] in vacuo like certain of the oxychlorides and oxybromides. The positions of the protactinium-oxygen... 

Antimony trioxid—Antimonous anhydrid—Oxid of antimony —Antimonii oxidum (U. S. Br.)—SbaOs—388—occurs in nature and is prepared artificially by decomposing the oxychlorid or by heating Sb in air.
