Kupanga Zopangira
Zopangira zopangira acetylaniline makamaka zimaphatikizapo aniline ndi acetone. Pakati pawo, aniline ndi onunkhira amine, ndi chimodzi mwa zinthu zofunika kwambiri organic zopangira mankhwala, chimagwiritsidwa ntchito utoto, mankhwala, utomoni kupanga, mphira ndi zina. Acetone, monga acetylation agent, ndi gawo lapakati pamakampani opanga nayonso mphamvu komanso chinthu chofunikira kwambiri pakupanga organic synthesis.
Acetanilide nthawi zambiri imapangidwa ndi acetylation, yomwe ndi momwe aniline ndi acetone amapanga acetanilide. Zomwe zimachitika nthawi zambiri zimachitika pamaso pa zinthu zamchere monga sodium hydroxide kapena hydroxylamine, ndipo kutentha komwe kumakhala 80-100 ℃. Pochita izi, acetone imakhala ngati acetylation, m'malo mwa atomu ya haidrojeni mu molekyulu ya aniline ndi gulu la acetyl kupanga acetanilide. Zomwezo zikamalizidwa, zinthu zoyera za acetanilide zitha kupezedwa ndi acidization, kusefera ndi njira zina zaukadaulo.
Kugwiritsa ntchito
1. Mitundu ya utoto: ngati wapakatikati womwe umagwiritsidwa ntchito popanga utoto wa utoto, monga kusindikiza ndi kuyika utoto, zida zopaka utoto, chakudya, mankhwala ndi madera ena.
2. Mankhwala osokoneza bongo: Amagwiritsidwa ntchito ngati zipangizo popanga mankhwala enaake ndi mankhwala, monga diuretics, analgesics ndi anesthetics.
3. Zonunkhira: Zitha kugwiritsidwa ntchito ngati zokometsera, monga zokometsera.
4 synthetic resin: itha kugwiritsidwa ntchito kupanga utomoni wosiyanasiyana, monga phenolic resin, urea formaldehyde resin, etc.
5. Kupaka: kungagwiritsidwe ntchito ngati dispersant utoto kuti ❖ kuyanika, kusintha mtundu mphamvu ya utoto ndi adhesion filimu utoto.
6. Rubber: angagwiritsidwe ntchito ngati zopangira za organic kupanga mphira, Angagwiritsidwenso ntchito monga mphira plasticizer ndi buffer.
Zowopsa: Gulu la 6.1
1. Kulimbikitsa chapamwamba kupuma thirakiti.
2. Kudya kungayambitse chitsulo ndi mafupa hyperplasia.
3. Kuwonekera mobwerezabwereza kumatha kuchitika. Kukwiyitsa khungu, kungayambitse dermatitis.
4. Kuletsa chapakati mantha dongosolo ndi mtima dongosolo.
5. Kukhudzana kochuluka kungayambitse chizungulire ndi kutumbuka.
