Abstract: Unsaturated ketones, comprising optionally substituted but-3-enyl and/or buta-2.3-dienyl methyl ketones, are prepared by: (a) reacting allyl alcohols and/or propargyl alcohols with isopropenyl ethers, with formation of ketals as by-product; (b) preparing isopropenyl ethers by catalytic gas phase reaction of ketals with propyne and/or allene; and (c) feeding the ketal from stage (a) into stage (b). The but-3-enyl methyl ketones of formula (Ia) and but-2,3-dienyl methyl ketones of formula (Ib) formed, allyl alcohols of formula (IIa) and/or propargyl alcohols of formula (IIb) and isopropenyl ethers (III) used as starting materials are ketals (IV). R1, R2, R3, R4, R5 = H or (cyclo)alkyl, (cyclo)alkenyl or ar(alk)yl (optionally containing O); or R1R2 = 5-6-membered ring; and R6 = 1-4C alkyl. (III) are prepared by the gas phase reaction of (IV) and propyne or allene at elevated temperature in the presence of a heterogeneous catalyst containing Zn or Cd plus Si and O.

Abstract: An alkaline silicate suspension is reacted with an aqueous solution of a zinc salt at normal pressure and at temperatures between 50 degrees C and the boiling point of the suspension arising. It is alternatively reacted under hydrothermal conditions at the suspension boiling point up to 250 degrees C. Aqueous pH value is held at 4-9.5 throughout. The Zn/Si atom ratio is kept within 1.6-2.5. Preferred Features: From the product, a suitable zinc silicate, is formed. This has the hemimorphite structure as claimed, the composition Zn4Si2O7(OH)2-2yOy.xH2O, where x and y are between 0 and 1. To this end the product is roasted at temperatures of 70-600 degrees C. pH is maintained in the region 5.5-8 or 6-7.5. When reactin other salts, 0-20 mol% of the following group A, referred to zinc, is used with 0-20 mol% of the following group B, referred to silicon, (i.e. the elements in the hemimorphite structure described). Group A comprises: beryllium, magnesium, calcium, strontiu barium, manganese, iron, cobalt, nickel, copper, cadmium and mercury. Group B comprises: titanium, zirconium, hafnium, germanium tin and lead
