Abstract
A method of producing a granular substance comprising (i) a step of melting a compound of the formula (1): (wherein, R1 and R2 represent each independently a hydrogen atom, alkyl group having 1 to 8 carbon atoms or cycloalkyl group having 5 to 8 carbon atoms, R3 represents a hydrogen atom or alkyl group having 1 to 8 carbon atoms. X represents a single bond, sulfur atom, oxygen atom, alkylidene group having 1 to 8 carbon atoms or cycloalkylidene group having 5 to 8 carbon atoms) to obtain the melted substance, and (ii) a step of dropping the melted substance obtained in the step (i) into water and recovering the granular substance.
