Abstract
A method for producing a granular composition including the steps of: stirring and granulating a mixture containing not less than 3 parts by weight and not more than 80 parts by weight of a phenol compound represented by the formula (1): wherein Ris an alkyl group having 1 to 8 carbon atoms, X is an n-valent alcohol residue having 1 to 18 carbon atoms optionally containing a heteroatom, a cyclic group, or a heteroatom and a cyclic group, and n is an integer of 1 to 4, and not less than 20 parts by weight and not more than 50 parts by weight of a binder to obtain a granular agglomerate; and cracking the granular agglomerate at a temperature equal to or lower than the melting point of the binder and equal to or higher than the temperature which is 10° C. lower than the melting point, through a cracking machine equipped with a separation mechanism capable of recovering a granule having a particle size of not more than 5 mm, and a cracking mechanism, to obtain a granule.
