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:A solid phase synthetic method for preparing arylretinamides is provided. The method comprises reacting hexachloroacetone with a solvent-suspended resin-bound triphenylphosphine to provide a suspension comprising an activated chlorinating reagent; reacting retinoic acid with the activated chlorinating reagent to provide retinoyl chloride; adding pyridine and a select arylamine to the resulting mixture; and stirring the resulting mixture for a time and at a temperature sufficient for the select arylamine to react with the retinoyl chloride and provide the arylretinamide. Also provided, are select arylretinamides that can be prepared by the present method, and methods of using such arylretinamides to induce apoptosis in cancer cells.
