CURED RESORCINOL RESIN PARTICLES, METHOD FOR PRODUCING THE SAME, AND CARBON PARTICLES AND ACTIVE CARBON PARTICLES OBTAINED USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a technique to produce fine cured resorcinol particles industrially advantageously without using a protective colloid within a reaction time of 5 hours to obtain cured resorcinol resin particles, and to provide cured resorcinol resin particles obtained thereby, and carbon particles and active carbon particles obtained by using such resin particles.SOLUTION: To produce cured resorcinol resin particles having an average particle diameter of 2 μm or less by reacting resorcinol and aldehydes including at least formaldehyde using an organic acid catalyst comprising an alkylbenzene sulfonic aid having an alkyl group having 8 or more carbon atoms in an aqueous medium where a protective colloid is absent.
