摘要： A method for producing a carrier for a catalyst comprising the steps of mixing solutions of a soluble salt of aluminum and a soluble salt of silicic acid in a ratio that gives a precipitate comprising aluminum silicate having a weight ratio of Al.sub.2 O.sub.3 :SiO.sub.2 of 1:5 to 1:7, forming the precipitate into a carrier body, consolidating the carrier body by heating, and contacting the carrier body with an acid to reduce the Al.sub.2 O.sub.3 content to 1-5%. Thus produced carrier bodies are useful for catalyzing the hydration of olefins to alcohols when impregnated with phosphoric acid.

摘要： A water-free mixture of isopropyl alcohol, diisopropyl alcohol, diisopropyl ether and by-products is made by the catalytic hydration of propylene in the gaseous phase at temperatures of 140.degree.-170.degree.C under pressures of 25-40 atmospheres gauge. A water-to-propylene molar ratio of 0.1 to 0.25:1 is maintained in the hydration reaction. The crude product from the hydration reaction is dehydrated or dewatered in two columns without using a foreign withdrawing agent. Instead, diiosopropyl ether formed in the process itself is utilized as the withdrawing agent which is subsequently added to the water-free mixture together with additionally formed by-products. The water-free mixture formed according to the process can be used directly as an additive to gasoline fuel for motor vehicles.

摘要： Olefins having two and three carbon atoms are hydrated in the presence of phosphoric acid-containing supported catalysts to the corresponding alcohols. For the hydration of olefins having two carbon atoms, the molar ratio of water to olefin is in the range of about 0.1-0.3 : 1, the reaction temperatures in the range of about 190.degree.-230.degree.C, and the reaction pressure is in the range of about 60-80 atmospheres gauge. For the hydration of olefins having three carbon atoms, the molar ratio of water to olefin is in the range of about 0.1-0.3 : 1, the reaction temperatures in the range of about 140.degree.-170.degree.C and the reaction pressure is in the range of about 20-45 atmospheres gauge. The only by-products which form in addition to the raw alcohol under these conditions are steam-volatile (water soluble) by-products which are separated from the raw alcohol in a washing extraction zone. The by-products are recycled in aqueous solution without organic phase to the hydration in the state in which they are producted at the top of the washing extraction zone after separating unreacted olefin.

摘要： Crude glyoxal solutions obtained for example by the oxidation of acetaldehyde with nitric acid are purified by removing volatile acids followed by neutralization. Thereafter, the glyoxal is converted into a glyoxal glyoxal-di-(alkylhemiacetal) with an alcohol containing 1 to 3 carbon atoms with water removal during the conversion. After separating salts and other impurities, the glyoxal-di-(alkylhemiacetal) is hydrolyzed with water at elevated temperatures to yield pure glyoxal hydrate.
