Kupanga Zinthu Zopangira
Zipangizo zopangira acetylaniline makamaka zimaphatikizapo aniline ndi acetone. Pakati pawo, aniline ndi amine wonunkhira, ndi imodzi mwa zipangizo zofunika kwambiri zopangira mankhwala achilengedwe, zomwe zimagwiritsidwa ntchito kwambiri mu utoto, mankhwala osokoneza bongo, ma resin opangidwa, mphira ndi zina. Acetone, monga wothandizira acetylation, ndi gawo lofunika kwambiri pamakampani opanga fermentation komanso mankhwala oyambira pakupanga organic.
Acetanilide nthawi zambiri imapangidwa ndi acetylation, yomwe ndi momwe aniline ndi acetone zimachitikira kuti apange acetanilide. Kawirikawiri zimachitika pamene pali zinthu zoyambitsa alkaline monga sodium hydroxide kapena hydroxylamine, ndipo kutentha kwa reaction nthawi zambiri kumakhala 80-100℃. Mu reaction, acetone imagwira ntchito ngati acetylation, m'malo mwa atomu ya hydrogen mu molekyulu ya aniline ndi gulu la acetyl kuti apange acetanilide. Pambuyo poti reaction yatha, zinthu za acetanilide zoyera kwambiri zitha kupezeka mwa kuletsa acid, kusefa ndi njira zina zaukadaulo.
Kugwiritsa ntchito
1. Utoto wa utoto: monga chogwiritsira ntchito popanga utoto wa utoto, monga utoto wosindikizira ndi utoto, zinthu zopaka utoto wa nsalu, chakudya, mankhwala ndi zina.
2. Mankhwala: Amagwiritsidwa ntchito ngati zinthu zopangira popanga mankhwala ena ndi mankhwala, monga okodzetsa, ochepetsa ululu ndi oletsa ululu.
3. Zokometsera: Zingagwiritsidwe ntchito ngati zonunkhira zopangidwa, monga zonunkhira.
4 utomoni wopangidwa: ungagwiritsidwe ntchito popanga utomoni wosiyanasiyana, monga phenolic resin, utomoni wa urea formaldehyde, ndi zina zotero.
5. Chophimba: chingagwiritsidwe ntchito ngati chotulutsira utoto chopaka utoto, kupititsa patsogolo mphamvu ya utoto ndi kumatira kwa utoto wa utoto.
6. Rabala: ingagwiritsidwe ntchito ngati zopangira zopangidwa ndi rabala yopangidwa ndi organic, ingagwiritsidwenso ntchito ngati pulasitiki ndi buffer ya rabala.
Zoopsa: Kalasi 6.1
1. Kulimbikitsa njira yopumira ya pamwamba.
2. Kumeza kungayambitse kuchuluka kwa iron ndi bone marrow hyperplasia.
3. Kuwonekera mobwerezabwereza kungachitike. Kukwiyitsa khungu, kungayambitse dermatitis.
4. Kuletsa dongosolo lapakati la mitsempha ndi dongosolo la mtima.
5. Kukhudza kwambiri kungayambitse chizungulire komanso kufiira.
