Procedure
Example 1 is repeated, except that the fine silver catalyst is replaced by a silver fraction of particle size 1.0-2.5 mm in a 100 mm deep bed. On feeding 44 l (S.T.P.) of air, 113 g of 3-methyl-3-buten-1-ol vapor and 21.5 g of steam per hour per pipe into the reactor, a maximum temperature in the catalyst of 440° C. (salt bath temperature 385° C.) gives 520 g of uncoverted 3-methyl-3-buten-1-ol and 53.6 g of 3-methyl-2-butenal, corresponding to a 3-methyl-3-buten-1-ol conversion of 54% and a selectivity of 90%.
