Sulfide - an overview | ScienceDirect Topics

The oxidation of the propargyl sulfide (469) with MCPBA and sodium carbonate as base was accompanied by a prototropic rearrangement to the corresponding allene sulfone (470); the same product was formed by oxidation of the parent allene sulfide (471). An acyl group in the 5-position makes a 2-sulfonyl derivative very prone to hydrolytic reactions.

Refractory Gold Ore Treatment Methods

It is generally known that antimony can be readily volatilized, and by roasting stibnite (Sb2S2) in an oxidizing atmosphere, antimony oxide can be driven off and condensed. At the same time, anyone who has had experience with such roasting knows that it is a delicate process. To begin with it is impossible to drive off the antimony completely.
