Quinoline

Introduction:

quinoline, also known as benzopyridine, naphthyridine, is a heterocyclic aromatic organic compound which is a colorless, hygroscopic liquid with a strong odor.

Resource:

Quinoline containing 83%; Isoquinoline 15%; methylquinoline 2% crude quinoline can be used as a source of isoquinoline, but usually in the cut 237.5-239.5C crude quinoline fraction segment, then cutting the fractions of 243-246C were used as starting materials for the extraction of isoquinoline. This fraction segment partially separated 13-28% of 2-methylquinoline in hydrochloride and 3.

9% of quinoline. The isoquinoline fraction in an alcoholic solution is reacted with 98% sulfuric acid, at 35%C, to form the isoquinolinesulfonate. Upon cooling, the isoquinoline sulfonate crystallizes prior to its homolog sulfonate. After filtration, with 85% ethanol for recrystallization, and then 20% ammonia decomposition, after the formation of the oil layer washed with water, cut 242-243C fraction, then get the purity greater than 95% of isoquinoline
