Abstract: Catalyst for reducing carbon monoxide by means of hydrogen so as to obtain a mixture consisting substantially of C1-C4-hydrocarbons. The catalyst is made by precipitating a salt of a hydrocyanic acid of the general formula MeIMeII(CN)x, separating and drying the salt so precipitated and forming it. In the formula, the cationic component Me I stands for at least one of the elements Ce, Cu, Co, Ni, Fe, Mn, Zn, Ag and K or a mixture of these elements, or for Ca or Mg in admixture with (NH)4; the anionic component MeII stands for at least one of the elements Cu, Co, Ni, Fe, Mn, Zn and Ag or a mixture of these elements; and x stands for the sum of the metal valencies; MeI and MeII are not permitted to stand for iron alone, or for a mixture of iron with copper.

Abstract: The oxidation of carbon monoxide and hydrocarbons, in particular from exhaust gases from internal-combustion engines, by means of oxygen-containing gases to give carbon dioxide and water is carried out at temperatures of from 150 to 800 C in the presence of a supported catalyst. The supported catalyst here comprises aluminium oxide which has been partially converted into alpha -Al2O3 as support, to which from 0.2 to 10% by weight of cerium as oxide has been applied as active constituent.

Abstract: 1318689 Glycerol di- and tri-acetates KNAPSACK AG 2 Nov 1971 [14 Nov 1970] 50882/71 Heading C2C Glycerol triacetate and glycerol diacetate are prepared by reacting a solution of allyl acetate in acetic acid containing between 1À5 and 15 wt. per cent of acetaldehyde with a mixture of molecular oxygen and inert gas, (e.g. N 2 , carbon oxides), at 30-250 C. and 1-200 ats. absolute in the absence of catalysts. The acetic acid solution preferably contains 0À1-1À0 moles of acetaldehyde per mole of allyl acetate. The glycerol acetates may be hydrolysed by conventional methods to yield pure glycerol and the reaction may be carried out continuously.

Abstract: The invention relates to a process for making ethylene by subjecting a gas mixture containing hydrocarbons, hydrogen, carbon monoxide, carbon dioxide and steam to a hydropyrolysis reaction. More particularly, the gas mixture is heated to temperatures higher than 800 DEG C. inside a reaction zone having metal walls. The walls contain aluminum and/or copper in at least their surface portions.

Abstract: 1397957 Detergents containing builders HOECHST AG 14 Sept 1972 [24 Sept 1971] 42706/72 Heading C5D [Also in Division C2] Builders for detergent and cleansing agents comprise water-soluble salts of acid carboxylic acid esters prepared by reacting at least trivalent, 6-10C, aliphatic olefinically unsaturated carboxylic acids or hydroxy-carboxylic acids with aliphatic alcohols (3-6 OH groups), and in which each hydroxylic group of the alcohol and optionally the hydroxycarboxylic acid is esterified with a carboxylic acid molecule. Citric, aconitic, tricarballylic, dihydroxy-tricarballylic, nitrotriacetic and ethylenediamine-tetracetic acids may be used with glycerol, erythritol, pentaerythritol, mannitol, sorbitol or sugar alcohol (4-6 C) and the salts are of alkali metal or ammonium ion. A proportion of 10-80% by weight of salts may be used and then ion-active and/or non-ionic tensides and further conventional additives may be present. Examples describe the use of builders prepared from glycerol, sorbitol or pentaerythritol with nitric acid used with dodecylbenzene sulphonate, tallow fatty alcohol and hardened tallow soap, and also with additional magnesium silicate, sodium silicate, sodium perborate, sodium sulphate and tylose in detergent wash liquors.
