Abstract

Fremgangsmåte for fremstilling av en fysikalsk stabil krystallinsk ^-modifikasjon av para-amino-benzensulfa- nylamld omfatter av kjøling av en para-amino-benzen- sulfanylamldoppløsnlng i vann eller et organisk oppløsningsmiddel ved en hastighet på minst 2'C/mln. for fullstendig krystallisasjon derav og etterfølgende separering av resulterende krystaller og tørking derav.
