Abstract:
Providing a process for advantageously producing spherical particles of furfuryl alcohol resin using only furfuryl alcohol without using a harmful aldehyde as a starting material. In the process, furfuryl alcohol is subjected to a self-condensation reaction in the presence of an acid catalyst, whereby a fluidic condensation resin of furfuryl alcohol is obtained. The condensation resin of furfuryl alcohol is granulated and cured using water as a reaction medium in the presence of a dispersion stabilizer and an acid catalyst having a pKa of not more than 1.5, whereby spherical cured resin particles are formed.
