Abstract: Diesters of olefinically unsaturated 1,2- and/or 1,4-diols are prepared by reacting a conjugated diolefin, oxygen and a fatty acid, in the gas phase or liquid phase, over a solid catalyst which contains palladium and/or platinum and a further metal, which has an atomic number of from 21 to 30, from 39 to 48 or from 57 to 80, but is not a platinum metal, the catalyst having been obtained by reduction of compounds, applied to a carrier, of platinum and/or palladium and the further metal, and heating at 400 DEG C. or above.

The proportions of (A)p and (B)q are in the form of chemical compsns. differing from their local environment. A and B are distributed relative to each other such as a mixt. of finely divided A and finely divided B, with the proviso that B contains crystals B* of oxometallates of formula CuMoaWbVcNbdTeOy (II) (where, a/(A+B+C+D+E)=0.7-1.3; (B+C+D+E)/A = 0.01-1; and Y = a value determined by the valency and frequency of elements in (II) different from oxygen) of a new structure type (HT-Cu molybdate) defined by the X-ray diffraction pattern: d(A)=6.79+/-0.3; 3.56+/-0.3; 3.54+/-0.3, 3.40+/-0.3; 3.04+/-0.3, 2.96+/-0.3; 2.67+/-0.2; 2.66+/-0.2; 2.56+/-0.2, 2.36+/-0.2; 2.35+/-0.2; 2.27+/-0.2; 2.00+/-0.2;1.87+/-0.3; 1.70+/-0.2; 1.64+/-0.2; 1.59+/-0.2; 1.57+/-0.2; 1.57+/-0.2; 1.55+/-0.2; 1.51+/-0.2; 1.44+/-0.2.

Its atomic space arrangement is determined by powder X-ray diffraction (the intensity A of the diffracted X-ray beam as a function of two-fold diffraction angle (2&thetas; )) using Cu-K alpha -radiation ( lambda = 1.54178 Angstrom ), so that in the 2&thetas; region of 5-50 degrees the following diffraction lines are produced: Al(X-ray diffraction line) = 8.3 plus or minus 0.7 (2&thetas; degrees ); A2=14.4 plus or minus 0.7; A3=22.3 plus or minus 0.2; A4=23.5 plus or minus 0.7; A5=27.2 plus or minus 0.4; A6=32.0 plus or minus 0.8; A7=34.8 plus or minus 0.6; A8=38.7 plus or minus 0.5; A9=45.4 plus or minus 0.4; and A10=48.8 plus or minus 0.4.
