Chiyambi
Zopaka utoto (zopaka utoto) ndi gawo lofunika kwambiri pamakampani opanga mankhwala abwino, ndipo kukula mwachangu kwa makampani opanga utoto (zopaka utoto) kumadalira pakukula kwa zinthu zomwe zimagwirizana nazo.

Kupanga utoto ndi zinthu zopaka utoto ku China kwakhala kukukula kwambiri kuyambira m'ma 1950, chifukwa cha mpikisano waukulu pamsika, utoto ndi zinthu zopaka utoto zakhala zatsopano pakupanga ukadaulo; kupita patsogolo pakupanga mitundu yatsopano, njira yabwino yopangira, kafukufuku wa njira zatsopano, kugwiritsa ntchito mitundu yakale, kuteteza chilengedwe, ndi zina zotero, kugwiritsa ntchito ukadaulo woyera popanga utoto ndi zinthu zopaka utoto.

Choyamba, chitukuko cha kugwiritsa ntchito zinthu zapakati
Chithunzi

Ndipotu, chitukuko cha kugwiritsa ntchito zinthu zosakaniza chili ndi mbali zambiri, chinthu china chomwe chimagwiritsidwa ntchito popanga utoto chotchedwa zinthu zosakaniza utoto, ndipo chimagwiritsidwa ntchito popanga mankhwala ophera tizilombo, mankhwala ndi zinthu zosakaniza tizilombo, zinthu zosakaniza mankhwala. Zinthu zosakaniza ziyenera kuonedwa ngati nthambi ya makampani opanga mankhwala abwino kwambiri, siziyenera kugawidwa molimba m'magulu a zinthu zosakaniza utoto, zinthu zosakaniza tizilombo, zinthu zosakaniza mankhwala malinga ndi mafakitale, zomwe zimachepetsa kugwiritsa ntchito zinthu zina zosakaniza utoto ndikukhudza chitukuko chake.

Kafukufuku wa mankhwala osakaniza bwino amadziwika ndi mitundu yosiyanasiyana, kuwonjezera pa mitundu yochepa ya sikelo yopangira ndi yayikulu kwambiri, mitundu yambiri ya matani si yayikulu kwambiri, koma njira yokonzekera nthawi zambiri imakhala yovuta, yomwe imaphatikizapo machitidwe ambiri a mayunitsi ndi njira yolekanitsira, kupanga kunapanganso "zinyalala zitatu" zomwe ziyenera kusamalidwa bwino. Chifukwa chake, tiyenera kuchita kafukufuku wazinthu zotsatizana ndikukonzekera kupanga zinthu zosakaniza moyenera kuti tipeze phindu labwino.

Kuchokera kumayiko akunja, kafukufuku ndi kupanga zinthu zapakati nthawi zambiri zimakhala zokhazikika bwino kuti zikwaniritse kupanga zinthu zingapo, zida zopangira zimatha kupanga mitundu ingapo mpaka khumi ndi iwiri ya zinthu zapakati, kafukufuku wotere ndi kupanga kudzera mu chitukuko chonse, kugwiritsa ntchito ukadaulo watsopano ndikosavuta kugwiritsa ntchito, kudzakwaniritsa zotsatira zake kawiri ndi theka la khama. Mkhalidwe wa Japan ukhoza kukhala woti tiganizire, kupanga koyambirira kwa zinthu zapakati ku Japan nakonso kwafalikira kwambiri, kuyambira m'ma 1960 kwakhala kokwanira kasanu ndi kawiri kuti kukonzedwe, kuyang'ana kwambiri.

Kudzera mu kusintha ndi chitukuko, makampani opanga utoto ndi utoto ku China afika pamlingo wapamwamba pankhani ya kukula kwa kupanga, ukadaulo ndi zida, zomwe sizingokwaniritsa zosowa za chitukuko cha makampani opanga utoto ndi utoto m'dziko, komanso zimaperekanso zinthu zabwino kwambiri kwa mayiko akunja.

Zipangizo zofunikira popanga zinthu zosakaniza zimapezeka makamaka kuchokera ku zinthu zopangidwa ndi mafuta ndi mankhwala opangira makemikolo, zomwe zambiri ndi benzene, naphthalene, anthraquinone, komanso mankhwala ena a heterocyclic, ndipo utoto wachilengedwe wopangidwa ndi zinthu zosakaniza za heterocyclic ukuwonjezeka m'zaka zaposachedwa. Kuphatikiza apo, phenanthrene, pyridine, oxygen fluorene, quinoline, indole, carbazole, biphenyl series of compounds, zinthu zovuta izi zomwe zimagwiritsidwa ntchito popanga utoto, ndiye kuti kugwiritsa ntchito zinthu zopangira kudzakhala kwakukulu komanso kofala kwambiri.

Chachiwiri, machitidwe omwe amagwiritsidwa ntchito kwambiri a mankhwala apakati
Chithunzi

Zipangizo zopangira zidzakonzedwa kukhala utoto (mtundu) wamakampani omwe amagwiritsidwa ntchito kwambiri ndi mankhwala monga awa.

(1) kuchitapo kanthu kwa sulfonation
(2) Kuyankha kwa nitration
(3) kachitidwe ka halogenation
(4) Kuchepetsa kwa zochita pokonzekera amino
(5) Diazotization reaction (nthawi zambiri imayenderana ndi coupling reaction)
(6) alkali fusion reaction kuti ilowe m'malo mwa gulu la sulfonic acid kukhala hydroxyl
(7) Kuyankha kwa Acylation
(8) Kuchuluka kwa okosijeni m'thupi
(9) kuzizira ndi kusungunuka kwa mpweya m'thupi
(10) Kuyankha kwa kununkhira (makamaka amino)
(11) kusinthana kwa magulu a hydroxyl ndi amino
(12) hydroxyl kapena amino hydrocarbonation reaction

Malinga ndi kapangidwe ka mphete yayikulu ya mankhwala abwino, zinthuzi zitha kugawidwa m'magulu awiri: aliphatic system, benzene system, naphthalene system, anthraquinone system, heterocyclic system ndi thick ring system.
