摘要:A synthesis of the micro-porous silica gel and its application to preparation of catalysts for C 2 oxygenates synthesis from syngas is invented. The small particles of silica gel which are, produced by sol gel process are heated in a basic solution, followed by drying and/or calcinations, and thus form micro-porous silica as catalyst support. The basic solution can be one or a mixed solution of hydroxides, carbonates, bicarbonates, formates and acetates of alkali metal and ammonium. The obtained micro-porous silica can be impregnated with the solutions of rhodium salt and other transition element salts (as promoter precursors), followed by drying and/or calcinations, thus forming a micro-porous silica supported rhodium based catalyst. The rhodium salt can be RhCl 3 or Rh(NO 3 ) 3 . The promoter precursors can be water-dissolvable transition metal salts, rare earth metals salts, alkali metal salts and alkali earth metal salts. The obtained catalysts show high activity and selectivity in the synthesis of C 2 -oxygenates by the hydrogenation of CO under mild process conditions.

摘要:Methods for the synthesis of cyclic peptides are provided, as well as novel dipeptide compounds. The methods include the solid phase synthesis of a dipeptide, which is the coupled to a second peptide in a solid phase reaction. The peptide is then cyclized following the coupling reaction. The methods and dipeptides are particularly useful for the synthesis of MC-4 receptor agonist peptides.

摘要:A ruthenium-phosphine complex can be used as a catalyst in a method for the catalytic synthesis of urea. The method may comprise more particularly a reaction of formamide or of formamide with ammonia in the presence of the catalyst to form urea and hydrogen. Through the use of the ruthenium-phosphine complex as the catalyst, catalytic preparation of urea from formamide or from formamide with ammonia is provided for the first time. This allows for synthesis under mild conditions and virtually no formation of byproducts. Further, using an acid as a cocatalyst in the catalytic synthesis or the reaction can lead to an improvement in urea yield.
