Elemental sulfur coarsening kinetics
BACKGROUND Elemental sulfur exists is a variety of forms in natural systems, from dissolved forms (noted as S8(diss) or in water as S8(aq)) to bulk elemental sulfur (most stable as α-S8). Elemental sulfur can form via several biotic and abiotic processes, many beginning with small sulfur oxide or polysulfidic sulfur molecules that coarsen into S8 rings that then coalesce into larger forms: [For...
متن کامل11398: Investigation of Elemental Sulfur Corrosion Mechanisms
Sour gas wells frequently co-produce elemental sulfur which can cause catastrophic corrosion of mild steel. As producing wells become increasingly sour, the incidence of sulfur corrosion will likely increase. Despite the severity of this problem, limited mechanistic information about this process exists in the literature. The objective of this study is investigation of the corrosion mechanism i...
متن کاملToxicity of elemental sulfur for brucellae.
In previous reports we have described the toxicity of certain peptones and amino acids, particularly cystine, for brucellae (Schuhardt, Rode, Foster, and Oglesby, 1949; Schuhardt, Rode, and Oglesby, 1949). Subsequently, we found and reported that cystine per se is not toxic for these organims, and proved that the observed toxicity of autoclaved cystine is due to a heat-induced breakdown product...
متن کاملReaction of elemental sulfur with a copper(I) complex forming a trans-mu-1,2 end-on disulfide complex: new directions in copper-sulfur chemistry.
Elemental sulfur (S8) was found to react with [(TMPA)CuI(CH3CN)]+ to form the trans-mu-1,2 end-on disulfide complex [(TMPA)Cu-S-S-Cu(TMPA)]2+. The X-ray structure of this centrosymmetric disulfide complex shows a Cu(1)-S(1) bond length of 2.280(2) A and a S(1)-S(1A) bond length of 2.044(4) A.
