2-PHENYLPROPIONIC ACID C화학적 특성, 용도, 생산
화학적 성질
clear pale yellow to yellow liquid용도
2-Phenylpropionic acid is used in the preparation of ibuprofen derivatives for their anti-inflammatory activity. Also used in nucleation inhibitors in Dutch resolution of diastereomers.정의
ChEBI: A 2-arylpropionic acid carrying a phenyl group at position 2. It is a metabolite of alpha-methylstyrene (AMS), a volatile hydrocarbon.Synthesis
2-Phenylpropionic acid is prepared:1) from Benzyl cyanide by Metbylation with Methyl iodide and Sodamide to produce alpha-Phenylpropionitrile, from which the acid is produced by acid hydrolysis.
2) from Acetophenone cyanhydrin with Hydriodic acid.
Purification Methods
Fractionally distil the acid, or recrystallise it from pet ether (b 40-60o) with strong cooling (see references below). [Beilstein 9 II 348.]2-PHENYLPROPIONIC ACID 준비 용품 및 원자재
