Antimony chloride reagent

Oxides and peroxides can occur in many essential oils by a photochemical reaction. 1,8-Cineol and linalool monoxide can be readily separated on silica gel thin layers with 1-nitropropane-hexane (1 1, v/v), as the mobile phase.In this case, they have exhibited Rf values of 73 and 8, respectively. " Another pair of compounds, ascaridole and 1,8-cineol, can be easily separated on a silica gel layer, obtaining a value for chloroform as the mobile phase of 63 and 54, respectively. The antimony chloride reagent gives a gray color. The potassium iodide-acetic acid-starch test is usually better than ferrous thiocyanate. 

Visualisation of the terpenoid substances is best with the anisalde-hyde-sulphuric acid reagent (No. 11), antimony chloride reagents (Nos. 15, 18) or molybdophosphoric acid (No. 168) (cf. also [312]). 

If pieces of iron are added to a solution, and the mixture is filtered, tin(II) ions can be detected with mercury(II) chloride reagent. A similar result is obtained on boiling the solution with copper or antimony. 

Other useful organometallic reagents for the preparation of tertiary stibines or related heterocyclic compounds are compounds of lithium, aluminum, tin, copper, zirconium, and other metals. " In most cases, these metal compounds are reacted with antimony chlorides or bromides. Good yields of tertiary stibines were, however, also obtained by the interaction (equation 3) of triaUcylaluminium reagents and tris(dimethylamino)stibine. ...
