Formaldehyde → 2,6-Dihydroxybenzaldehyde

Participants

Reaction Steps

100 ml of the dried particles from Example 2 of size 10 μm were dispersed in a solution containing 150 ml water, 20 g resorcinol and 60 g formaldehyde solution (37%). The resulting mixture was kept at 70° C. for 1.5 hours under stirring. After cooling to ambient temperature the particles were separated from the reaction mixture and washed with water on a sieve of mesh size 37 μm. The particles had a diameter of 68 μm in water and shrank somewhat in air to 61 μm diameter.
