Usage |
|
Usage limitation | FEMA(mg/kg): Soft drinks 0.25,, cold drinks 0.25, sweets1.0; bakery products 0.004-1.0, moderate use (FDA§172.515,2000). |
Preparation |
Crude quinoline containing 83% quinoline, 15% isoquinoline and 2% methyl quinoline can be used as the raw material for the production of isoquinoline. However, the Distillation section from 237.5-239.5℃ and 243-246℃ is generally collected and used as the raw material for the extraction of isoquinoline. 13-28% of 2-methyl quinoline and 3.9% quinoline can be separated from this distillation section in the form of hydrochloride salt. The isoquinoline fraction reacted with 98% sulfuric acid at 35℃ in alcohol solution to produce isoquinoline sulfonate. Isoquinoline sulfonate crystallizes faster than its homologues in the cooling process. After filtration, recrystallization was carried out with 85% ethanol, and then decomposed with 20% ammonia water. The generated oil layer was firstly washed with water, and then rectified to collect the fraction at242-243℃to obtain Isoquinoline with purity greater than 95% It is separated by repeated freezing the coal tar with the boiling rangeat 238~250℃. |
