    only one documented case, that of PbS2 which adopts two polymorphic forms corresponding to Pb(IV)(S2−)2 and Pb(II)(S22−). Here we have taken advantage of metathetic reactions using salts of weakly coordinating anions and we have prepared for the first time Ag(I)2S2O8, silver(I) peroxydisulphate. The title compound crystallizes in the non-centrosymmetric Cc space group with partial disorder of the anionic

  • Anhydrous processing of methane into methane-sulfonic acid, methanol, and other compounds

    Anhydrous processing to convert methane into oxygenates (such as methanol), liquid fuels, or olefins uses an initiator to create methyl radicals. These radicals combine with sulfur trioxide to form methyl-sulfonate radicals. These radicals attack fresh methane, forming stable methane-sulfonic acid (MSA) while creating new methyl radicals to sustain a chain reaction. This system avoids the use or creation of water, and liquid MSA is an amphoteric solvent that increasing the solubility and reactivity of methane and SO 3 . MSA from this process can be sold or used as a valuable chemical with no mercaptan or halogen impurities, or it can be heated and cracked to release methanol (a clean fuel, gasoline additive, and chemical feedstock) and sulfur dioxide (which can be oxidized to SO 3 and recycled back into the reactor). MSA also can be converted into gasoline, olefins, or other valuable chemicals.
    无水处理将甲烷转化为氧化物(如甲醇)、液体燃料或烯烃,使用引发剂产生甲基自由基。这些自由基与三氧化硫结合形成甲基磺酸盐自由基。这些自由基攻击新鲜的甲烷,形成稳定的甲烷磺酸(MSA),同时产生新的甲基自由基以维持链式反应。该系统避免使用或产生水,并且液体MSA是一种两性溶剂,增加了甲烷和SO3的溶解性和反应性。通过这一过程得到的MSA可以作为有价值的化学品出售或使用,不含硫醇或卤素杂质,也可以加热裂解释放甲醇(一种清洁燃料、汽油添加剂和化学原料)和二氧化硫(可以氧化为SO3并循环回反应器)。MSA还可以转化为汽油、烯烃或其他有价值的化学品。
  • Process for producing anhydrous peroxydisulfuric, acid using sulfur trioxide recovered from a waste comprising sulfuric acid

    A process for producing peroxydisulfuric acid from a waste comprising substantially sulfuric acid, whereby the sulfuric acid is separated into sulfur trioxide and substantially water which is removed as a waste. The recovered sulfur trioxide is reacted with hydrogen peroxide to produce peroxydisulfuric acid which is fed to a methane-sulfonation process resulting in formation of sulfuric acid radicals. The sulfuric acid radicals react with methane producing methane radicals resulting in formation of sulfuric acid. The sulfuric acid from the methane-sulfonation process is recovered, reprocessed, and the process is repeated.

    A method of processing a semiconductor wafer sliced from a single-crystal ingot and having front and back surfaces and a peripheral edge comprises the step of plasma jet etching the wafer to reduce the sub-surface wafer damage. The method further comprises high-gloss etching the wafer by subjecting the wafer to a high-gloss etchant that smooths the wafer such that surface roughness and nonspecularly reflected light are reduced. Plasma assisted chemical etching (PACE) is performed on the wafer to improve the flatness and the thickness uniformity of the wafer. The wafer is final polished to further reduce surface roughness and nonspecularly reflected light.
