Abstract
<PICT:0940393/C3/1> Whisker-like crystals of copper phthalocyanine are produced by passing a stream of carbon dioxide containing suspended copper phthalocyanine powder into an inlet passage A maintained at 760 DEG C. and passing the resulting vapour-containing gas into a vessel E, whiskers being condensed out in a zone B maintained at 150 DEG C. The gas flows through chamber E at a rate of 6 1./min.
