发明名称 Verfahren zur Suspensionskristallisation
摘要 The invention concerns a method of separating a crystallizable organic compound from a liquid compound mixture by means of a single- or multi-stage suspension crystallization method, the crystals behind the final stage being separated by a washing column and a mother liquor, which is depleted of the compound to be separated by crystallization, being channelled out of the first stage. The method is characterized in that the crystal phase is separated out of the suspension before the suspension is introduced into the washing column and is resuspended in a mother liquor whose liquidus temperature is no more than 8.5 DEG C below the melt temperature of the crystal phase.
