Abstract: Carboxylic acid esters of vicinal glycols are prepared by oxidizing olefins with oxygen in the presence of carboxylic acids and of halogen and tellurium salts as catalysts, the reaction being carried out in vessels and apparatus consisting of, or lined with, zirconium or alloys of not less than 80% by weight of zirconium, the remainder being tin and/or hafnium.

Abstract: Mono- and poly-ethylene glycol dialkyl ethers I R1-O-(-CH2-CH2-O-)n-R2 where R1 is C1-C4-alkyl, R2 is C3-C5-alkyl and n is from 1 to 100, are prepared by reacting monoalkyl ethers II R1-O-(-CH2-CH2-O-)n-H with a C3-C5-olefin III in the presence of an acid ion exchanger at from 1 to 200 bar and from 40 DEG to 150 DEG C., the reaction being started at from 100 DEG to 150 DEG C. and the temperature then being lowered, in at least two approximately equal steps, to from 40 DEG to 80 DEG C., the temperature being dropped in each case to the next-lower level when the conversion per unit time no longer changes significantly.

Abstract: A method of manufacturing ethylbenzene in high yield by catalytic aromatization of the C8-cycloolefins obtained in the dimerization of unsaturated C4-hydrocarbons is described. By-products attributable to cracking, isomerization and decomposition of the raw material into its starting materials are virtually not detectable in the reaction product. The aromatization product can therefore be converted to styrene without prior distillation or purification.

Abstract: 1286983 Contacting gases with liquids; gas/ liquid catalytic reactions; controlling exothermic reactions BADISCHE ANILIN- & SODAFARIK AG 18 Sept 1969 [19 Sept 1968] 45983/69 Headings B1F B1R and B1X In an exothermic catalytic reaction involving a gaseous reactant and carried out in the presence of a liquid reaction medium containing a dissolved or suspended catalyst a portion of the liquid reaction medium is withdrawn during the reaction and recycled to the remaining liquid reaction medium through a nozzle at a speed of 5 to 100 metres per second at the point where the gaseous reactant is introduced below the surface of the liquid reaction medium, the recycled liquid reaction medium being introduced into an open-ended chamber located in the liquid reaction medium and extending in the direction of entry of the recycled liquid reaction medium and which has an inlet opening with a mean diameter of from 2 to 20 times the mean diameter of the nozzle and a length of 3 to 30 times its hydraulic diameter, and heat is withdrawn from the liquid reaction medium outside the open-ended chamber. In the apparatus shown in the drawing liquid reaction medium is withdrawn from vessel 4 (which may be jacketed) by a pump 6 passed through a cooler 11 and returned via line 7 and nozzle 1 at the upper end of an open-ended chamber 3. Gaseous reactant enters at 2 and further heat is withdrawn from the reaction by means of a cooling coil 12. The gaseous reactant may react with a second reactant which is dissolved in and/or suspended in the liquid reaction medium. The second reactant may also be gaseous. The gaseous reactant may be hydrogen and the catalyst a hydrogenating catalyst.
