摘要 The present invention relates to a process for the manufacture of adipic acid, more particularly of adipic acid crystals.It relates more specifically to a process for the treatment of the adipic acid crystals obtained on conclusion of crystallization, which consists in dispersing the adipic acid crystals collected on conclusion of crystallization in a liquid medium, in stirring the said liquid medium and in then separating the said crystals from the said liquid medium and optionally drying them.The form of the crystals is modified in order to obtain pebbles with a substantially smooth surface.
