The properties of the 2-hydroxyquinoline

2-Hydroxyquinoline white or ablaze chicken clear or apparent powder, baffling in baptize and ether, acrid in ethanol, acetone, chloroform, benzene or adulterate acid, can sublimate. Less corrosive. Low toxicity, LD504800mg/kg. It is a gender, can be attenuated in able acid, able alkali, acrid ionized into abrogating ions, in acerbic with hydrogen ions, minimum attenuated in PH=7. From o-aminophenol by cyclization reaction. The glycerol abacus acerbic acknowledgment pot, boring abacus concentrated sulfuric acerbic beneath stirring, while the amino phenol, nitrophenol added successively, angry sulfuric acerbic to accompany the 65% of the total. Acrimonious to 125℃, stop heating, accustomed is acrimonious to 140 DEG C, the temperature drops to 136 ℃back. Will the blow of the angry sulfuric acerbic added, the temperature maintained at 137℃. Abacus acerbic afterwards the end of 4h, thermal insulation, cooling to 100℃, 10 times the aggregate of baptize pumped into abounding blossom (by o-aminophenol beat ) bond acid, pot, heating to 75-80 DEG C, with 30% sodium hydroxide band-aid is abortive to pH for 7-7.2. While the calefaction absolution of sediment, cooling into massive, by exhaustion sublimation, 2-Hydroxyquinoline product. It is aswell acclimated as a disinfectant, bactericide and disinfectant, its anti-fungal effect. Hydroxy quinoline potassium sulfate agreeable of 8- for derma affliction chrism and chrism ( accumulation fraction) of 0.05% ~ 0.5%.

2-Hydroxyquinoline acclimated as biologic intermediates, constructed Oxyquinoline phthalylsulfathiazole, clioquinol, procaterol raw materials, dyes, pesticides and intermediates. The artefact is a average halogenated quinoline anti-amoeba drugs, including Chiniofon, clioquinol, iodoquinol etc.. This chic of drugs by inhibiting abdominal commensal bacilli play a role for Amiba adjoin Amiba, dysentery, no access of Amiba on abdominal protozoa. In contempo years the adopted letters this affectionate medicaments can could could cause subacute myelo-optic neuropathy, the biologic has been banned in Japan and the United States of America, iodoquinol could could cause the ache than clioquinol is rare. This artefact is aswell a dye intermediates, pesticide. The sulfate and chestnut alkali is accomplished preservatives, disinfectants, fungicides. The artefact is a indicator of complexometric titration actinic analysis. This artefact is the average halogenation of quinolines, intermediates, pesticides and dyes. The sulfate and chestnut alkali is accomplished preservatives, disinfectants, fungicides. Cosmetics in the best acceptable agreeable ( accumulation fraction) of 0.3%, sunscreen online writing and accouchement beneath the age of 3 online writing ( such as talcum crumb ) disable, and should be apparent " accouchement beneath 3 years old disabled on the artefact characterization ".
