Evaluation of the pyrophoric risk of sulfide mineral in storage.
Spontaneous combustion of the sulfide mineral is one of the major challenge during the sulfide mineral storage and transportation. To evaluate the pyrophoric risk of the sulfide mineral, the thermo-gravimetry and differential scanning calorimetry (TG-DSC) technique were employed to evaluate the thermal behavior of the sulfide concentrate sample. The samples were heated from ambient temperature to ...

An Examination of the Steric and Electronic Effects in the Copolymerization of Carbonyl Sulfide and Styrene Oxide
关键字:Carbonyl Sulfide, Copolymerization,Styrene Oxide
The completely alternating copolymerization of carbonyl sulfide (COS) and styrene oxide was found to occur under mild reaction conditions (0?30 °C and 1.5 MPa) in the presence of (salen)CrCl/onium salt catalyst systems to afford high molecular weight poly(monothiocarbonates) with narrow molecular weight distributions. Ring-opening of styrene oxide was shown to be 88% selective&nb...
