Abstract: Iron-based homogeneous catalysts, supported by pincer ligands, are employed in the catalytic dehydrocoupling of ethanol to produce ethyl acetate and hydrogen. As both ethanol and ethyl acetate are volatile materials, they can be readily separated from the catalyst by applying vacuum at room temperature. The hydrogen by-product of the reaction may be isolated and utilized as a feedstock in other chemical transformations.

Abstract: Processes for forming a vulcanizable elastomeric formulation are disclosed. The processes include the steps of mixing an elastomer with a vulcanizing agent to form a vulcanizable elastomeric formulation that includes the vulcanizing agent dispersed in the elastomeric compound, wherein the vulcanizing agent includes a cyclododecasulfur compound. A process for forming a vulcanized elastomeric article is also described.

Abstract: Disclosed is a process for the purification of a mixed diol stream. The mixed diol stream comprising two-, three-, and four-carbon diols is separated into component diols by extraction with a hydrophobic solvent mixture. The diols recovered in the extractant may be removed from the extractant stream by back extraction with water or by distillation with an azeotrope-forming agent present, preferably an azeotroping agent already present in the extractant mixture.
