    摘要： The present application pertains to processes producing oxides using a weak acid intermediate. In one embodiment a material comprising calcium carbonate is reacted with a solution comprising aqueous carboxylic acid to form a gas comprising carbon dioxide and a solution comprising aqueous calcium carboxylate. The solution comprising aqueous calcium carboxylate is reacted with sodium sulfate to form a solution comprising aqueous sodium carboxylate and a solid comprising calcium sulfate. The solution comprising aqueous sodium carboxylate is reacted with sulfur dioxide to form sodium sulfite and an aqueous carboxylic acid. The sodium sulfite is separated from said aqueous carboxylic acid and reacted to form a solid comprising calcium sulfite which is decomposed to form calcium oxide and sulfur dioxide.

    摘要： The present invention relates to molecular isotopic engineering. The present invention relates to a method or process for preparing a target compound of a statistically defined isotopic composition comprising the step of reacting one or more reactant compounds, wherein each reactant compound is of a statistically defined isotopic composition. The reactant compound is reacted in a chemical process or a biological process thereby generating an isotopic mass balance, or further, an isotopic fractionation to produce the target compound. The present invention also relates to a statistically defined isotopic composition of a target compound. The statistically defined isotopic composition comprises an internal marker, and can be used as, for example, a security feature, an identity indicator, or a purity indicator of the target compound.

    摘要： The present disclosure includes a system and method for producing a first product from a first region of an electrochemical cell having a cathode and a second product from a second region of the electrochemical cell having an anode. The method may include a step of contacting the first region with a catholyte comprising carbon dioxide, producing a first product which may include carbon monoxide or an alkli metal formate. The method may include another step of contacting the second region with an anolyte comprising a sulfur-based reactant and producing a second product including oxygen and sulfur dioxide. Further, the method may include a step for introducing the separated oxygen from second region of the electrochemical cell with a hydrogen sulfide stream in a catalyst reactor bed, converting the hydrogen sulfide to sulfur dioxide. The sulfur dioxide may then be liquefied as a product, or a portion of the sulfur dioxide may be recycled to the second region of the electrochemical cell where it may be converted to sulfuric acid. The sulfuric acid may then be reacted with another reactant, such as ammonia, to produce an ammonium sulfate product.
