The carbonization behavior of phenol-formaldehyde resin (PF) blended in the presence of simple organic substances of m-phthalic acid (PA), trimesic acid (TMA), and phloroglucinol (PG) was studied. The weight loss and heat flow were monitored to study their carbonization behavior by TGA and differential scanning calorimetry (DSC), respectively. Pore formers showed different interactions between PF and pore formers during their heating process, and these interactions occured at different temperature range, depending on the type of pore formers added in PF. The PA had small interactions between PF during heat treatment. The TMA indicated an additional interaction above 650 K. The PG had large interactions from a lower temperature, emerging ∼ 450 K. Phenolic group in pore formers interacted strongly with PF than carboxylic group does, thus changing the carbonization behavior during heating process of PF resin. This is an abstract of a paper presented at the AIChE Annual Meeting (Austin, TX 11/7-12/2004).
