kampani ya mit-ivy industry
CEO@mit-ivy.com
moni, uyu ndi CEO athena wochokera kumakampani a mit-ivy a mankhwala ku China.
Zapakati: Mitundu ya Dyestuff ndi nthambi yofunika kwambiri yamakampani abwino kwambiri amankhwala, ndipo kukula kwachangu kwamakampani opanga utoto kumadalira kukula kwapakati komwe kumapita nawo.
Kupanga utoto ndi mitundu ya pigment ku China kwapangidwa kwambiri kuyambira 1950s. Ndi mpikisano wochulukirachulukira pamsika, zopaka utoto ndi pigment zapangidwa muukadaulo wopanga; apanga zopambanitsa m’mbali zingapo monga kupanga mitundu yatsopano, kuwongolera kapangidwe kake, kufufuza njira zatsopano, ntchito zatsopano zamitundu yakale, kuteteza chilengedwe, ndi zina zotero, ndi kutengera luso laukhondo lopanga utoto wa utoto ndi utoto wa pigment.

Kukula kwa intermediates 'ntchito

M'malo mwake, kugwiritsiridwa ntchito kwachitukuko chapakati kumapangidwa mosiyanasiyana, chapakati china chomwe chimagwiritsidwa ntchito mu utoto wotchedwa dye intermediates, ndipo chimagwiritsidwa ntchito mu mankhwala ophera tizilombo, mankhwala ophera tizilombo, mankhwala opha 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 chawo.

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. Kuonjezera apo, phenanthrene, pyridine, oxygen fluorene, quinoline, indole, carbazole, biphenyl mndandanda wa mankhwala, zovuta zowonongeka zomwe zimagwiritsidwa ntchito popanga utoto, ndiye kuti kugwiritsa ntchito zipangizo zamakono kudzakhala kofala komanso kofala.

Ambiri zimachitikira mankhwala ntchito intermediates

Kukonza zinthu zopangira utoto (mtundu) zapakati pazomwe zimagwiritsidwa ntchito kwambiri ndizomwe zimagwiritsidwa ntchito 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 mitundu yopitilira 400 yamitundu yapakati monga benzene, naphthalene, anthraquinone, heterocyclic ndi mitundu ina yopaka utoto ndi pigment, yomwe imatha kukwaniritsa zosowa zamakampani opanga utoto ndi utoto.
