Title: POWDERY 1,4-CYCLOHEXANEDICARBOXYLIC ACID
Abstract:
In order to provide a high-purity 1,4-cyclohexanedicarboxylic acid powder having excellent powder flow properties, the present invention provides a high-purity 1,4-cyclohexanedicarboxylic acid powder in which: the grain size distribution (volume reference) of the powder is such that D10 is within the range of 5-55 µm, D50 is 40-200 µm, and D90 is within the range of 170-800 µm; the loose bulk density is 0.4-0.8 g/cm3; the tight bulk density is 0.5-1.0 g/cm3; and the degree of compaction is 10-23%.
