Kusungunuka
Sungunuka mu ethanol, acetone, chloroform, benzene ndi mineral acid, pafupifupi osasungunuka m'madzi.
8-hydroxyquinoline ndi amphoteric, imasungunuka mu ma acid ndi ma base amphamvu, imasinthidwa kukhala ma ion osafunikira m'ma base, imalumikizidwa ku ma ion a hydrogen mu ma acid, ndipo imakhala ndi kusungunuka kochepa kwambiri pa pH = 7.
Kugwiritsa ntchito mwapadera
1. Monga mankhwala ochiritsira, si mankhwala opangira kexieling, chloroiodoquinoline ndi paracetamol okha, komanso ndi mankhwala ochiritsira ndi mankhwala ophera tizilombo. Mankhwalawa ndi mankhwala ochiritsira a quinoline opangidwa ndi halogenated anti amoeba, kuphatikizapo quiniodoform, chloroiodoquinoline, diioquinoline, ndi zina zotero. Mankhwalawa amagwira ntchito yolimbana ndi amoeba poletsa mabakiteriya am'mimba. Ndi othandiza pa kamwazi wa amoeba ndipo sakhudza protozoa ya amoeba yomwe ili kunja kwa matumbo. Zanenedwa kuti mankhwala amtunduwu amatha kuyambitsa matenda a msana, choncho aletsedwa ku Japan ndi ku United States. Diioquinoline imayambitsa matendawa pang'ono kuposa chloroiodoquinoline. 8-hydroxyquinoline ndi mankhwala ochiritsira ndi mankhwala ophera tizilombo. Mchere wake wa sulfate ndi mkuwa ndi mankhwala abwino kwambiri otetezera, ophera tizilombo komanso ophera mildew. Mankhwalawa ndi chizindikiro cha completometric cha kusanthula mankhwala.
2. Monga chothandizira komanso chochotsera mpweya ndi kulekanitsa ayoni achitsulo, imatha kuyanjana ndi Cu+ 2kukhala+ 2, Mg+ 2, Ca+ 2, Sr+ 2, Ba + 2 ndi Zn+ 2、Cd+2、Al+3、Ga+3、In+3、Tl+3、Yt+3、La +3、Pb+2、B+3、Sb+ 3、Cr+3、MoO+ 22Kusokonezeka kwa Mn+ 2,Fe+ 3, CO+ 2, Ndi+ 2, PD+ 2, CE+ 3, ndi ma ayoni ena achitsulo. Kusanthula kwachilengedwe, muyezo wodziwira heterocyclic nitrogen, kapangidwe ka organic. Ndiwonso pakati pa utoto, mankhwala ophera tizilombo ndi ma quinolines a halogenated. Mchere wake wa sulfate ndi mkuwa ndi zosungira zabwino kwambiri.
3. Kuyika guluu wa epoxy resin kungathandize kulimbitsa mphamvu yolumikizirana ndi kukana kutentha ku zitsulo (makamaka chitsulo chosapanga dzimbiri), ndipo mlingo wake nthawi zambiri umakhala 0.5 ~ 3 phr. Ndi mankhwala a halogenated quinoline anti amoeba, komanso mankhwala ophera tizilombo ndi utoto. Itha kugwiritsidwa ntchito ngati choletsa mildew, chosungira mafakitale, chokhazikika cha polyester resin, phenolic resin ndi hydrogen peroxide, komanso ngati chizindikiro cha complexometric titration cha kusanthula mankhwala.
4. Chogulitsachi sichili chapakati pa mankhwala a halogenated quinoline okha, komanso chapakati pa utoto ndi mankhwala ophera tizilombo. Mchere wake wa sulfate ndi mkuwa ndi mankhwala abwino kwambiri osungira, ophera tizilombo komanso ophera bowa. Chiwerengero chokwanira (chidutswa chachikulu) mu zodzoladzola ndi 0.3%. Zinthu zoteteza ku dzuwa ndi zinthu zogwiritsidwa ntchito kwa ana osakwana zaka 3 (monga ufa wa talcum) ndizoletsedwa, ndipo "zoletsedwa kwa ana osakwana zaka 3" ziyenera kuwonetsedwa pa chizindikiro cha chinthucho. Pochiza matenda a khungu omwe ali ndi mabakiteriya komanso eczema ya bakiteriya, kuchuluka kwa 8-hydroxyquinoline mu emulsion ndi 0.001% mpaka 0.02%. Chimagwiritsidwanso ntchito ngati mankhwala ophera tizilombo, ophera tizilombo toyambitsa matenda komanso ophera tizilombo toyambitsa matenda, ndipo mphamvu yake yolimbana ndi bowa ndi yamphamvu. 8-hydroxyquinoline potassium sulfate imagwiritsidwa ntchito mu kirimu wosamalira khungu ndi lotion (chidutswa chachikulu) kuyambira 0.05% mpaka 0.5%.
