Oxidation of rosalva (9-decen-1-ol) to costenal (9-decen-1-al) was carried out in silicon-glassmicroreactors on silver catalysts at the temperature range 420-475°C. Reactors with increasedsurface area where silver was deposited were employed with a view to enhance reactionperformance. The results showed a significant improvement of the reaction with silverdeposited on porous silicon surface. Rosalva conversion increased from 8-35% on non-poroussilicon to 67-95% on porous silicon under the same reaction conditions (rosalva:O 2 :He=1:3:57, residence time=20 ms). Selectivity to costenal higher than 95% was also achieved
