Isoquinoline Usage And Synthesis

Chemical Properties	Colorless flaky crystal or liquid, similar fragrance to bitter almonds and Chervil, sweet taste, melting point 23℃，boiling point 243℃, soluble in ethanol and non-volatile oil, diluted inorganic acid and most organic solvents, slightly soluble in water.
Usage	A kind of Spice Mainly used for the preparation of vanilla spice. Used in the production of pesticides, medicine, rubber accelerator, color film sensitizing agent, dyes, anion exchange resin and so on. Used as gas chromatographic stationary liquid and analytical reagent, Used in the pharmaceutical industry. Used for the production of drugs for prevention and treatment of schistosomiasis (praziquantel), antimalarial, chemical reagents, etc. Isoquinoline can be oxidized to produce Pyridine carboxylic acid And Its derivatives can be used for the production of color films and dyes. It can be used as Iron preservative, soluble phenolic resin curing agent, etc. Its Addition compounds formed with metals can be used for the quantitative determination of nickel and cadmium and the qualitative determination of noble metal. Isoquinoline can also be used as a catalyst in the benzoylation reaction and polymerization of α-olefin.
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℃.
Content analysis	Determined by Gas chromatography and liquid chromatography and the chromatographic test conditions are the same as α-allyl ionone (03411).
Category	flammable liquid
Toxicity grade	middle toxic
Toxicity	GRAS(FEMA)
Acute toxicity	Oral – rat LD50: 360mg/kg
Stimulus data	Skin-rabbit 10 mg/24h mild; eye-rabbit 250 μg severe.
Flammability hazard characteristics	Flammable in case of fire, high temperature and oxidants, Combustion produces toxic nitrogen oxide smog.
Storage	Completely packed, handle with care; Ventilated warehouse, away from open flame, high temperature, separated from strong acids.
Fire extinguishing agent	foam, carbon dioxide, dry powder, dry sand, water spray.
Chemical Properties	LIGHT BROWN LOW MELTLING SOLID
