설명

일반 설명

Pyrrolidine is a five membered cyclic amine. It is a nitrogen heterocycle that forms the nucleus of various bioactive molecules. It can be synthesized by reacting 1,4-diaminobutanes with acids. It behaves as a strong base in employed in certain homogeneous nonaqueous reactions. Its crystalline structure has been investigated. Its reaction on the Ge(100)-2×1 surface and Si(100)-2×1 surface has been investigated. Pyrrolidine has been found to be one of the component of volatile amine fraction in the brewing process. A study on the kinetics of pyrrolidinolysis of phthalimide (PTH) shows second- and third-order terms in the rate law. Biodegradation of pyrrolidine by Mycobacterium strains has been studied.

애플리케이션

Pyrrolidine may be used in the following studies:

• Synthesis of pyrrolidine derivatives of pyrimidine.
• As a catalyst in the selective monoallylation of allylic alcohols.
• To capture carbondioxide in a bubble column reactor using pyrrolidine aqueous solutions by gas–liquid absorption.
