Abstract

화합물질을 결정화 함으로써 이를 결정화하기 위한 방법에 관하여 기재한다. 결정화를 이용한 결정화에 있어서, 일반적으로 냉각에 의하여 수득된 결정으로 농축된 용해물을 비균질적인 결정자 분포를 갖는 용해물 내에 공급하기 때문에 제품화가 지연되는 문제점이 있다. 결정자로서 균일한 분포를 갖는 단일 분산질이며, 최소한 그 일부는 고형인 입자를 용해물 내에 공급하기에 앞서 그 용해물로부터 결정자를 수득하는 것이 특징이다.It describes a method for crystallizing a compound by crystallizing it. In crystallization using crystallization, there is a problem in that the commercialization is delayed because the lysate concentrated with crystals obtained by cooling is supplied into the lysate having a heterogeneous crystallite distribution. It is a single dispersoid with a uniform distribution as crystallites, characterized by obtaining crystallites from the lysate prior to feeding the solid particles into at least part of the solids.

이는 개선된 역류 방식에 의하여 수율이 향상되는 효과가 있다. 이는 용해된 물질을 결정화하거나 직접 과립을 제조하는데 응용될 수 있다.This has the effect of improving the yield by the improved backflow method. It can be applied to crystallize dissolved materials or to produce granules directly.
