1,4-Benzenedimethanol → Terephthalaldehyde

참여 물질

반응 단계

Using a similar method to Example 1, a mixture of 200 parts of 4-(hydroxymethyl)-benzyl alcohol and 400 parts of dioxane with 290 parts of air is passed per hour over the catalyst at 600° C. and 1.1 bar. The residence time is 0.05 second and the throughput is 0.3 tonne/m2.h. 124 parts of terephthaldialdehyde (in the form of a 22 percent strength by weight solution) are obtained per hour, corresponding to a yield of 63% of theory. The conversion is 92 percent and the space-time yield is 6 grams of terephthaldialdehyde per cm3 of catalyst volume per hour.
