kampani ya mit-ivy industry
CEO@mit-ivy.com
moni, uyu ndi CEO athena wochokera kumakampani a mit-ivy a mankhwala ku China.

Mawu Oyamba
Kupaka utoto (mtundu) wapakati ndi gawo lofunika kwambiri lamakampani opanga mankhwala abwino, ndipo kukula mwachangu kwamakampani opaka utoto (mtundu) kumadalira kukula kwapakati komwe kumapita nawo.

Kupanga utoto ndi ma pigment intermediates ku China kwapangidwa kwambiri kuyambira zaka za m'ma 1950, ndi mpikisano wochulukirachulukira pamsika, zopaka utoto ndi pigment zakhala zatsopano muukadaulo wopanga; zotsogola pakupanga mitundu yatsopano, njira zopangira bwino, kafukufuku wanjira zatsopano, kugwiritsa ntchito kwatsopano kwamitundu yakale, kuteteza chilengedwe, ndi zina zambiri, kugwiritsa ntchito ukadaulo waukhondo popanga utoto ndi utoto wamitundu.

Choyamba, kukula kwa ntchito intermediates
Chithunzi

M'malo mwake, chitukuko cha kugwiritsiridwa ntchito kwapakati chimakhala chochuluka, china chapakati chomwe chimagwiritsidwa ntchito mu utoto wotchedwa dye intermediates, ndipo amagwiritsidwa ntchito mu mankhwala ophera tizilombo, mankhwala ophera tizilombo, mankhwala ophera tizilombo. Intermediates ayenera kuonedwa ngati nthambi ya makampani abwino mankhwala lonse, sayenera rigidly ogaŵikana dyestuff intermediates, mankhwala intermediates, mankhwala intermediates ndi makampani, amene kuchepetsa kuchuluka kwa ntchito intermediates ena ndi zimakhudza chitukuko chake.

Zabwino mankhwala intermediates kafukufuku yodziwika ndi osiyanasiyana mitundu, kuwonjezera ochepa mitundu ya kupanga sikelo ndi yaikulu kwambiri, mitundu yambiri ya tonnage si lalikulu kwambiri, koma ndondomeko yokonzekera nthawi zambiri zovuta, kuphatikizapo zochita zambiri unit ndi ndondomeko kulekana. , kupanga kunatulutsanso kuchuluka kwa "zinyalala zitatu" zomwe ziyenera kusamalidwa bwino. Chifukwa chake, tiyenera kuchita nawo kafukufuku wazinthu zingapo ndikukonza zopanga zapakati moyenera kuti tipeze mapindu abwino.

Kuchokera kumayiko akunja, kafukufuku ndi kupanga apakati amakhala okhazikika bwino kuti akwaniritse kupanga mndandanda, zida zopangira zida zimatha kupanga mitundu ingapo mpaka khumi ndi iwiri yapakati, kafukufuku wotere ndi kupanga kudzera pachitukuko chonse, kugwiritsa ntchito teknoloji yatsopano ndiyosavuta kukhazikitsa, idzapindula kawiri zotsatira ndi theka la khama. Zinthu za ku Japan zitha kukhala zofotokozera zathu, kupanga koyambirira kwapakati ku Japan nakonso kunabalalika, kuyambira 1960s kwakhala kasanu ndi kawiri kuti asinthe, kuyang'ana.

Kudzera kusintha ndi chitukuko, China dyeing ndi pigment intermediates makampani wafika mlingo wapamwamba mawu a sikelo kupanga, luso ndi zipangizo mlingo, amene sangakhoze kokha kukwaniritsa zosowa za chitukuko cha mafakitale zoweta utoto ndi pigment, komanso kupereka kwambiri khalidwe intermediates. kwa mayiko akunja.

Zopangira zomwe zimafunikira pakuphatikizika kwa intermediates zimachokera kumafuta amafuta ndi makina opangira ma coking, ambiri mwa iwo ndi benzene, naphthalene, anthraquinone mankhwala, komanso mankhwala ena a heterocyclic, ndi ma organic pigments opangidwa ndi heterocyclic compounds intermediates. kuwonjezeka kwa zaka zaposachedwapa. Komanso, phenanthrene, pyridine, okosijeni fluorene, quinoline, indole, carbazole, biphenyl mndandanda wa mankhwala, izi zovuta zopangira ntchito kupanga utoto, ndiye kugwiritsa ntchito zopangira zopangira kudzakhala zambiri komanso chilengedwe.

Chachiwiri, ambiri ntchito mankhwala zimachitikira intermediates
Chithunzi

The zopangira adzakhala kukonzedwa mu utoto (mtundu) makampani intermediates ambiri ntchito zimachitikira mankhwala ndi motere.

(1) sulfonate reaction
(2) Kuchita kwa nitration
(3) halogenation reaction
(4) Kuchepetsa kuchitapo kanthu pokonzekera amino
(5) Diazotization reaction (nthawi zambiri imatsagana ndi kugwirizana)
(6) alkali maphatikizidwe anachita m'malo sulfonic asidi gulu kuti hydroxyl
(7) Acylation reaction
(8) Kuchita kwa okosijeni
(9) condensation ndi carbonation anachita
(10) Aromatization reaction (makamaka amino)
(11) kusinthana kwamagulu a hydroxyl ndi amino
(12) hydroxyl kapena amino hydrocarbonation reaction

Malinga ndi kapangidwe ka mphete yamafuta onunkhira bwino apakati, ma intermediates amatha kugawidwa kukhala aliphatic system, benzene system, naphthalene system, anthraquinone system, heterocyclic system ndi dongosolo la mphete wandiweyani. Dziko lathu limatha kupanga benzene, naphthalene, anthraquinone, heterocyclic system, monga utoto, pigment intermediates mitundu yopitilira 400, makamaka kuti ikwaniritse zosowa zamakampani opanga utoto.
