  摘要：

  本文披露了一种改进的方法，用于从脱硫/脱金属反应中再生材料。脱硫/脱金属反应最好具有产品，其中包括碱金属硫化物、多硫化物或氢硫化物，或碱土金属硫化物、多硫化物或氢硫化物中的一个或多个。该方法包括以下步骤：将脱硫/脱金属产物与卤素反应，从产物中释放和去除硫，然后电解卤化产物以将卤素与碱金属或碱土金属分离。

  The millimeter/submillimeter spectrum of LiSH (X̃1A′): further investigations of the metal–sulfur bond

  摘要：

  The pure rotational spectrum of USH and its Li-6 and deuterium isotopomers has been recorded in the region 73-521 GHz using millimeter/sub-millimeter direct absorption techniques. These species were created by the reaction of H2S or D2S and lithium vapor in a dc discharge. Extensive K-a ladder structure was observed for all three isotopomers, indicating that USH is a near-prolate asymmetric top with a (X) over tilde (1)A(1) electronic state. Rotational parameters have been determined for the three species, enabling the calculation of a r(m)((1)) structure. The Li-S-H bond angle was found to be 93degrees, indicating a high degree of covalent bonding in this molecule. (C) 2002 Elsevier Science B.V. All rights reserved.

  potential new building blocks for inorganic macrocycles of the type [P(μ-NR)}2(μ-S)]n. NMR spectroscopic studies and DFT calculations show that the preference for the cis or trans isomers of III is largely influenced by the steric demands of the R-group, with cis isomers being preferred for bulky substituents. This is an important factor in regard to applications in macrocycle synthesis since the cis

  compounds with stereochemical information and convertible functional units are valuable building blocks in synthetic chemistry. Si-stereogenic aminochlorosilanes are built up by Si−N bond formation between an achiral dichlorosilane and a chiral enantiomerically pure primary amine. Both diastereomers could be isolated as stereochemically pure single-crystals by fractional crystallization and were analyzed

  Disclosed herein is an improved method for regenerating materials from a desulfurization/demetallation reaction. The desulfurization/demetallation reaction preferably has products including one or more of an alkali sulfide, polysulfide or hydrosulfide, or alkali earth sulfide, polysulfide, or hydrosulfide. The method includes the steps of reacting the desulfurization/demetallation products with a halogen, liberating and removing sulfur from the product, and then electrolyzing the halogenated products to separate the halogen from the alkali metal or alkali earth metal.
