talofa, o le CEO lea o Athena mai le mit-ivy industry mo vailaʻau i Saina.

Folasaga
O le vali (lanu) intermediates o se lala e sili ona taua o le pisinisi vailaʻau lelei, ma o le televave o le atinaʻeina o le vali (lanu) alamanuia e faʻalagolago i le atinaʻeina o mea vavalalata e o faatasi ma ia.

O le gaosiga o le valiina ma le pigment intermediates i Saina ua atiina ae tele talu mai le 1950s, faatasi ai ma le faʻateleina o le tauvaga malosi i le maketi, vali ma pigment intermediates ua fou i tekinolosi gaosiga; faʻalavelave i le atinaʻeina o ituaiga fou, faʻaleleia le gaosiga o le gaosiga, suʻesuʻega i auala fou, faʻaoga fou o ituaiga tuai, puipuiga o le siosiomaga, ma isi, faʻaaogaina tekinolosi mama mo le gaosiga o le valiina ma le pigment intermediates.

Muamua, o le atinaʻeina o le faʻaogaina o mea tau
Ata

O le mea moni, o le atinaʻeina o le faʻaogaina o vailaʻau faʻapitoa e tele, o se mea faʻapitoa e faʻaaogaina i le vali e taʻua o le dye intermediates, ma faʻaaogaina i vailaau faʻasaina, vailaʻau ma taʻua o vailaau faʻasaina, vailaʻau faʻamaʻi. Intermediates e tatau ona manatu o se lala o le alamanuia kemikolo lelei i lona atoaga, e le tatau ona matua vaevaeina i dyestuff intermediates, vailaau e tineia ai manu faalafua, pharmaceutical intermediates e ala i alamanuia, lea o le a faaitiitia le lautele o le faaaogaina o nisi intermediates ma aafia ai lona atinae.

O suʻesuʻega faʻataʻitaʻiga vailaʻau lelei e faʻaalia i le tele o ituaiga, faʻaopoopo i nai ituaiga o fua o gaosiga e matua tele lava, o le tele o ituaiga o tone e le tele tele, ae o le sauniuniga e masani ona faigata, e aofia ai le tele o tali ma le vavaeeseina. , o le gaosiga foi na maua ai le tele o "tolu otaota" e manaʻomia ona taulimaina lelei. O le mea lea, e tatau ona tatou auai i le faagasologa o suʻesuʻega o oloa faʻasologa ma faʻatulagaina le gaosiga o mea faʻavaitaimi talafeagai ina ia maua ai faʻamanuiaga lelei.

Mai le tulaga o atunuu i fafo, o le suʻesuʻega ma le gaosiga o mea vavalalata e masani ona faʻatumauina lelei e ausia ai le gaosiga o faʻasologa, o se seti o meafaigaluega gaosiga e mafai ona maua mai ai le tele o ituaiga o vaʻavaʻa, o suʻesuʻega ma gaosiga e ala i le atinaʻe atoa, faʻaogaina o tekinolosi fou e faigofie ona faatino, o le a ausia faalua le taunuuga i le afa o le taumafaiga. O le tulaga o Iapani e mafai ona mo lo tatou faasinomaga, o le uluai gaosiga o intermediates i Iapani e matua faataapeapeina foi, mai le 1960 ua fitu taimi e fetuunai, taulai.

E ala i suiga ma atinaʻe, ua oʻo i le tulaga maualuga o le gaosiga o le gaosiga o le gaosiga, tekinolosi ma meafaigaluega, e le gata ina mafai ona faʻafetaui manaʻoga o le atinaʻeina o le valiina o le fale ma le pigmenti, ae faʻapea foʻi ona tuʻuina atu le tele o intermediates. mo atunuu i fafo.

O mea mataʻina e manaʻomia mo le tuʻufaʻatasia o mea vavalalata e masani lava ona maua mai i oloa o le suauʻu ma le gaosiga o vailaʻau kemisi, o le tele o ia mea o le benzene, naphthalene, anthraquinone compounds, faʻapea foʻi ma nisi o vailaʻau heterocyclic, ma o meaʻai faʻalaʻau saunia ma vailaʻau heterocyclic o loʻo i luga. le siitia i tausaga talu ai nei. E le gata i lea, o le phenanthrene, pyridine, oxygen fluorene, quinoline, indole, carbazole, biphenyl series of compounds, o nei mea faʻapitoa faʻapitoa e faʻaaogaina i le gaosiga o vali, ona faʻaogaina lea o mea faʻapipiʻi gaosia o le a sili atu ona lautele ma lautele.

Lona lua, o le fa'aaogaina masani fa'a'ona o vaila'au fa'atasi
Ata

O mea mata'ina o le a fa'agaoioia i vali (lanu) alamanuia intermediates e sili ona fa'aaogaina vaila'au fa'afoliga e fa'apea.

(1) tali sulfonation
(2) Tali fa'ama'i
(3) tali halogenation
(4) Fa'aitiitiga tali e saunia ai amino
(5) Diazotization tali (e masani ona o faatasi ma le sooga tali)
(6) alkali fusion tali e sui ai le sulfonic acid vaega i hydroxyl
(7) Tali acylation
(8) Fa'ali'i fa'ama'i
(9) condensation ma carbonation tali
(10) Fa'afofoga fa'afofoga (tele amino)
(11) fa'afesuia'i fa'afoliga o vaega hydroxyl ma amino
(12) hydroxyl po'o amino hydrocarbonation tali

E tusa ai ma le fausaga o le mama manogi autu o intermediates vailaʻau lelei, e mafai ona vaevaeina intermediates i faiga aliphatic, faiga benzene, faiga naphthalene, faiga anthraquinone, faiga heterocyclic ma faiga mama mafiafia. E mafai e lo tatou atunuu ona gaosia benzene, naphthalene, anthraquinone, heterocyclic system, e pei o le vali, pigment intermediates sili atu i le 400 ituaiga, e masani lava e fetaui ma le valiina, e manaʻomia le atinaʻeina o pisinisi.
