- Solution 1 and solution 2 are passed via separate lines into a precipitation vessel which is provided with a stirrer and contains 10 l of water heated to 60.degree. By adjusting the feed rates of solution 1 and solution 2, the pH was brought to 6.2.
- the filter cake was dried for 16 h at 12O 0 C and then calcined for 2 h at 300 0 C.
- the catalyst powder thus obtained is precompacted with 1% by weight of graphite.
- the compact obtained is mixed with 5% by weight of unicoat Cu sheet and subsequently with 2% by weight of graphite and pressed into tablets of 1.5 mm in diameter and 2 mm in height. The tablets were finally calcined for 2 hours at 35O 0 C.
- the catalyst thus prepared has the chemical composition 57% CuO / 28.5% Al 2 O 3 / 9.5% La 2 O 3 /5% Cu.
- the test duration was a total of 7 days.
- ester conversions of 99% and a hexane diol selectivity of 96.9% were detected in the reactor effluent at 190 ° C. After removal, the catalytic converter was still fully preserved and had a high mechanical stability.
- Table 1 The search results are summarized in Table 1.
- the comparative catalyst was prepared analogously to Catalyst 1, but pressed into tablets of 3 mm in diameter and 3 mm in height.
- the catalyst thus prepared has the chemical composition 57% CuO / 28.5% Al 2 O 3 / 9.5% La 2 O 3 /5% Cu.
- the lateral compressive strength in the oxidic and reductive state are listed in Table 1.

- the test duration was a total of 7 days.
- GC analysis were in the reactor effluent at 220 0 C and 24O 0 C Esterum accounts detected respectively 92.4% hexanediol contents of 88.8%.
- the catalyst was still fully preserved and had a high mechanical stability. The test results are summarized in Table 1.
