WebThe first part of the reaction, at around 70 °C, forms a thick reddish-brown tacky material, which is rich in hydroxymethyl and benzylic ether groups. The rate of the base-catalysed reaction initially increases with pH, and reaches a maximum at about pH = 10. WebThe phenolic is charred or pyrolized to produce a carbon matrix. Since the charring processes produces a porous structure due to the vaporization of the part of the phenolic, the process has to be repeated several times. tamdhu whisky glasses
