摘要:The method of preparing a silver catalyst for synthesis of formaldehyde by oxidizing methyl alcohol which consists in that a carrier is impregnated with an aqueous or an aqueous-alcohol solution containing complex ions of silver having the general formula [Ag(X) n ] + or [Ag(Y) 2 ] - , where X is ammonia, ethylenediamine, triethylenetetramine or triaminotriethylamine, Y is a thiocyanate, cyanide, acetate, or hydroxyl ion, and n is 1 or 2. The impregnated carrier is processed, at a temperature of from 10° - 100°C, with a reducing agent taken in the quantity sufficient to reduce the silver completely from said ion. The thus-prepared catalyst is dried at a temperature of from 80° to 400°C. It is recommended that the catalyst be washed with water before drying. The thus-prepared catalyst has a highly developed active surface with a small content of silver (the specific surface of the catalyst is 0.7 - 7 square meters per gram, with the metal silver content of the catalyst being from 5 - 10 per cent by weight). The catalyst is highly active and has good selectivity in the process of formaldehyde synthesis from methyl alcohol. The yield of formaldehyde with the proposed catalyst is from 75 - 80 per cent, calculating with reference to the passed methyl alcohol, with the selectivity of the process being from 89 - 95 per cent.

摘要:The presented invention relates to a method of synthesis of carbon-supported platinum group metal or metal alloy nanoparticles, which comprises the following steps:n adsorbing on carbon support complexes of a platinum group metal with a urea complexing agent selected from a group comprising urea, urea derivative, a mixture of urea with at least one urea derivative, and a mixture of at least two urea derivatives; and reducing the complexes adsorbed on the carbon support to metal nanoparticles, forming a product of carbon-supported metal nanoparticles. nn The invention also provides the use of the carbon-supported platinum group metal or metal alloy nanoparticles obtained by the method of the invention as catalyst. n The present invention further relates to a method of adsorption of precursors of platinum group metals on the surface of a carbon support and use of complexes of platinum group metals with urea complexing agent for adsorption of platinum group metal precursors on carbon support.

摘要:This invention is directed to methods of treating insulin resistance in a mammal which comprise administering an effective amount of a compound of formula I, n n nwhere the variables are defined in the specification, or the stereoisomeric mixtures, diastereomerically enriched, diastereomerically pure, enantiomerically enriched or enantiomerically pure isomers, or the pharmaceutically acceptable salts and prodrugs thereof to said mammal. The compounds of formula I are growth hormone secretagogues and as such are useful for increasing the level of endogenous growth hormone. In another aspect this invention provides certain intermediates which are useful in the synthesis of the foregoing compounds and certain processes useful for the synthesis of said intermediates and th compounds of formula I. This invention is further directed to methods comprising administering to a human or other animal a combination of a functional somatostatin antagonist such as an alpha-2 adrenergic agonist and a compound of formula I.
