Disclosed is a process for carrying out a cyclisation reaction, a polymerization reaction, an enzymatic reaction showing substrate inhibition, an enzymatic reaction showing product inhibition, a reaction showing precipitation of the substrate or of a reactant, the process comprising the steps of
a) diluting a fresh substrate with solvent to form a diluted substrate-solvent mixture, and supplying this mixture to a reactor,
b) causing the reaction medium in the reactor to react,
c) discharging reaction mixture comprising reaction product, solvent, and substrate that has not reacted, to a first filtration membrane which is permeable to the solvent and impermeable to the substrate and to the catalyst or at least one of the reactants,
d) returning solvent from the permeate side of the first membrane to dilute the fresh substrate, and
e) returning retentate comprising substrate which has not reacted, from the first filtration membrane to the reactor.
本发明公开了一种进行环化反应、聚合反应、展示底物抑制的酶反应、展示产物抑制的酶反应、底物或反应物沉淀反应的过程,该过程包括以下步骤:
a)将新鲜底物与溶剂稀释以形成稀释的底物-溶剂混合物,并将该混合物供应到反应器中;
b)使反应介质在反应器中反应;
c)将包括反应产物、溶剂和未反应的底物的反应混合物排放到第一过滤膜上,该膜对溶剂渗透性而对底物和催化剂或至少一种反应物不渗透性;
d)从第一膜的渗透侧返回溶剂以稀释新鲜底物;
e)从第一过滤膜返回未反应的底物的截留物到反应器中。
