Abstract:
A granulated diacetal composition comprising a powder of a diacetal represented by the formula (1) wherein R1 and R2 are the same or different and each represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, or a halogen atom, a and b each represent an integer of 1 to 5, and c represents 0 or 1, and a binder,the granulated diacetal composition being prepared by agitating a mixture containing a starting powder of the diacetal represented by the formula (1) and the binder at a temperature equal to or higher than the melting point or softening point of the binder and lower than the melting of the diacetal, and molding the resulting compound into grains, the diacetal particles in the granulated diacetal composition being bonded to each other via the binder and aggregated, the binder in the granulated diacetal composition coating a part or the whole of the surface of each diacetal particle or adhering to a part or the whole of the surface of each diacetal particle, the granulated diacetal composition prepared by molding the compound into grains having an apparent specific gravity of 0.5 to 1.4.
