    摘要: Free-flowing, non-agglomerating and attrition resistant, substantially spherical solid beads/spherules of a coumarin compound, advantageously having a particle size ranging from 100 .mu.m to 2,000 .mu.m, a loose bulk density ranging from 0.25 to 0.8 and a compressive strength ranging from 500 to 10,000 N/m.sup.2, dissolve rapidly in ethanol and are conveniently prepared by prilling/fragmenting a melt of the coumarin compound into a stream of a cooling gas.
