Abstract: A catalyst for ethylene oxide prodn. is prepd. by gas-phase reaction of ethylene with O2. The catalyst comprises a support, 2-12% Ag, and (based on Ag) 0.05-0.35 atom % K, 0.003-0.25 atom % Rb, 0.0005-0.2 atom % Cs or an equiv. amt. of a mixt. of these alkali metals. The process comprises impregnating the Ag-contg. support (opt. also contg. Na and/or Li) with a soln. (pref. alcoholic) contg. a cpd. of K, Rb and/or Cs and an amine and/or ammonia. The presence of an amine and/or ammonia in the impregnation soln. improves the selectively of the catalyst. The process is applicable to fresh catalysts rather than used or thermally stabilised catalysts.

Abstract: Supported catalysts containing silver and alkali metals, for the preparation of ethylene oxide from ethylene and oxygen in the gas phase, are prepared or regenerated by modifying, respectively, a new or spent supported catalyst which already contains metallic silver and may or may not contain the light alkali metals lithium and/or sodium and, where a spent catalyst is concerned, also contains the heavy alkali metals potassium, rubidium and/or cesium, with a solution containing the heavy alkali metals, the modifier solution used containing (a) a surfactant and/or a reducing agent, in the case of the preparation of a new catalyst or (b) a surfactant, in the case of the regeneration of a spent catalyst.

Abstract: Prepn. of N-acylamino-carboxylic or sulphonic acids (I) or their alkali metal salts comprises (a) preparing a suspension of a solid, anhydrous alkali metal salt (II) of an aminocarboxylic or aminosulphonic acid in an alkyl carboxylate ester (III); (b) carrying out reaction to prepare an alkali metal salt of (I), by adding a catalytic amt. of strong base; and opt. (c) converting the salt into free (I) by addn. of acid.

Abstract: A catalyst for the manufacture of ethylene oxide, giving improved yield and having a long life, based on an alkali metal-modified silver catalyst on an oxide carrier is obtained by providing the silver-containing catalyst, in the reduced state, with the alkali metal by applying an alcoholic alkali metal salt solution which also contains an organic oxygen compound or nitrogen compound which forms complexes with silver ions.
