Abstract: Novel alkali metal-promoted Ag catalysts claimed for use in direct oxidn. of ethylene to ethylene oxide are characterised by (i) having an alpha-Al oxide porous carrier of BET surface area 0.3-3 m2/g; and (ii) contg. tungsten as co-promoter in an amt., based on total catalyst wt., of 60-330 wt. ppm per m2 surface area per g of the carrier material. Ag content is 10-30 wt.% and the alkali metal is Li, Rb and/or Cs with prefd. amts. based on total catalyst wt., being 200-2000 wt.ppm for Cs and/or Rb and 100-1000 wt.ppm for Li. At least 99 wt.% of the carrier is of high-purity alpha-Al oxide.

Abstract: The preparation of enol-ethers of formula R3R4C=C(OR1)R2 is by gas phase reaction at 100-550 (especially 200-350) degrees C and 0.001-5 bar of acetals or ketals of formula R3R4HC-C(OR1)(OR1')R2 on a heterogeneous highly porous catalyst which is an oxide of a Gp. II, III or IV or sub-Gp. II or IV element, the catalyst having a pH of 7-14, a porosity of 40-80% and a BET surface area of 0.5-250 m /g. R1-5 = 1-20 C alkyl, 2-20 C alkenyl or 7-20 C phenylalkyl; R2-4 = H, aryl, CN, COOR5, 1-12 C alkyl (optionally 1-3 times substituted or interrupted by COOR5, CO, CN or 1-12 C alkoxy), aryl or 7-12 C phenylalkyl (each optionally 1-3 times substituted by 1-12 C alkyl, 1-12 C alkoxy, halogen or CN); R2/R4 or R3/R4 = together 3-10 C alkylene or 2-20 C alkylidene; and R1' = R1, but not necessarily the same.
