Amagwiritsidwa ntchito popanga zolerecretics ndi zonunkhira.
1. Mankhwala apakatikati: ogwiritsidwa ntchito ngati zapakatikati pazisankho zingapo zopangidwa ndi zopangidwa ndi zamankhwala, kuphatikizapo zamankhwala zopangidwa ndi mankhwala ndi zamankhwala zaulimi.
2. Mankhwala ogulitsa: Itha kugwiritsidwa ntchito popanga mankhwala ena komanso monga gawo la chemistry.
3. Utoto ndi utoto: 4-hydroxyacetopnoone imagwiritsidwa ntchito popanga utoto ndi utoto chifukwa chokhoza kuchita zinthu zingapo zokhudzana ndi mankhwala osiyanasiyana.
4. Antioxidants: Ali ndi antioxidant katundu ndipo amatha kugwiritsidwa ntchito popanga mapangidwe kuti aletse kuwonongeka kwazakota.
5. Kafukufuku: Mu labotale, nthawi zambiri zimagwiritsidwa ntchito pazifukwa zosiyanasiyana zamankhwala komanso kafukufuku wokhudzana ndi kapangidwe kabwino.
Amasungunuka mosavuta mu mowa, chloroform, mafuta onenepa ndi glycerol, komanso sungunuka pang'ono m'madzi.

1.1 Kusamala kwanu, zida zoteteza ndi njira zadzidzidzi
Gwiritsani ntchito zida zamwini. Pewani mapangidwe fumbi. Pewani kupuma ming'alu, kulakwitsa kapena
mpweya. Onetsetsani kuti mpweya wabwino kwambiri. Pewani kupuma fumbi.
1.2 Kusamala Zachilengedwe
Pewani kutayikira kwina kapena kunyamuka ngati kuli koyenera kutero. Musalole kuti malonda alowe m'madzi.
Kutulutsa malo kuyenera kupewedwa.
Njira 1.3 ndi zida za chizolowezi ndikuyeretsa
Nyamula ndikukonzekera popanda kupanga fumbi. Funsani ndi fosholo. Pitilizani
Zoyenera, zotsekedwa zotayidwa.
1.1 Chenjezo la Kugwiritsa Ntchito Motetezeka
Pewani kulumikizana ndi khungu ndi maso. Pewani mapangidwe fumbi ndi ma aerosols.
Perekani mpweya wabwino woyenera ku malo pomwe fumbi limapangidwa.
1.2 Mikhalidwe yosungirako bwino, kuphatikizapo kusamvana kulikonse
Sungani pamalo abwino. Sungani chidebe chotsekedwa bwino m'malo owuma komanso owuma.

1. Kutsatirana kwa ulamuliro: Chongani ndikutsatira malamulo adziko lonse komanso mayiko okhudzana ndi mayendedwe a mankhwala. Izi zimaphatikizapo gulu loyenera, kulembera ndi zolemba.
2. Ma CDGUGUGE: Gwiritsani ntchito zida zoyenerera zomwe zikugwirizana ndi 4-hydroxyacetopnonenone. Onetsetsani kuti chidebe ndi cholimba komanso chopota kuti mupewe poyenda.
3. Zolemba: Zolemba momveka bwino za dzina la mankhwala, chizindikiro chowononga, ndi chidziwitso chilichonse chothandiza. Izi zikuphatikiza kugwiritsa ntchito malangizo ndi chidziwitso chadzidzidzi.
4. Kuwongolera kutentha: Ngati ndi kotheka, onetsetsani kuti njira yoyendera kutentha kutentha kuti isawonongeke.
5. Pewani zinthu zosagwirizana: onetsetsani kuti 4-hydroxyacetoptoneone satumizidwa palimodzi ndi zida zosagwirizana monga oxidants okakamiza kapena ma asidi omwe angakhale nawo.
6. Mapepala a Chitetezo (SDS): Phatikizani pepala loteteza deta ndi kutumiza kwanu kuti mupereke chidziwitso pazowopsa, kuyendetsa, ndi njira zadzidzidzi.
7. Kuthandiza: Onetsetsani kuti ogwira ntchito omwe amakhudzidwa pantchito amaphunzitsidwa kuti azitha kugwiritsa ntchito zinthu zoopsa ndikumvetsetsa zoopsa zomwe zimakhudzana ndi 4-HPA.
8. Njira zadzidzidzi: Konzani njira zadzidzidzi ngati kutayikira kapena ngozi paulendo.
Inde, 4-hydroxyacetopnone imawoneka ngati yowopsa. Nazi mfundo zazikuluzikulu za zoopsa zake:
1. Chiwopsezo cha Zamoyo: Kulumikizana kapena kupasuka kungayambitse kukhumudwitsa khungu, maso ndi kupuma thirakiti. Kuwonekera kwa nthawi yayitali kapena mobwerezabwereza kumatha kuyambitsa thanzi lalikulu.
2. Chiwopsezo cha Zachilengedwe: Zitha kukhala zovulaza moyo wamadzi, chifukwa chisamaliro ayenera kumwedwa kuti alepheretse kumasulidwa kwawo.
3.
4. Kusungidwa ndi kutaya: Tsatirani malangizo osungiramo bwino komanso kutaya zinyalala zilizonse malinga ndi malamulo am'deralo kuti muchepetse chilengedwe.
