(EN) Antisolvent solidification process
(ZH) 反溶剂凝固方法
Abrégé
(EN)
The present invention relates to a antisolvent solidification process wherein a liquid medium comprising at least one organic or inorganic compound which is to be solidified is forced through a membrane into one or more antisolvents, or wherein one or more antisolvents are forced through a membrane into a liquid medium comprising at least one organic or inorganic compound which is to be solidified, yielding a composition comprising solid particles comprising said organic and/or inorganic compound(s).

(ZH)

本发明涉及一种反溶剂凝固方法,其中将含有至少一种待凝固的有机或无机化合物的液体介质强制通过膜进入一种或多种反溶剂中,或者其中将一种或多种反溶剂强制通过膜进入含有至少一种待凝固的有机或无机化合物的液体介质中,产生包含含有所述有机和/或无机化合物的固体颗粒的组合物。
