Intshayelelo
Izinto ezidibanisa imibala (umbala) lisebe elibaluleke kakhulu kwishishini leekhemikhali ezintle, kwaye uphuhliso olukhawulezileyo lweshishini lokudaya imibala luxhomekeke kuphuhliso lwezinto ezidibanisa imibala ezihamba nalo.

Ukuveliswa kwezinto ezidibanisa imibala kunye ne-pigment eTshayina kuye kwaphuhliswa kakhulu ukususela ngeminyaka yoo-1950, kunye nokhuphiswano olukhulayo kwimarike, izinto ezidibanisa imibala kunye ne-pigment ziye zaba zintsha kwitekhnoloji yemveliso; impumelelo ekuphuhlisweni kweentlobo ezintsha, inkqubo yokuvelisa ephuculweyo, uphando ngeendlela ezintsha, ukusetyenziswa okutsha kweentlobo ezindala, ukukhuselwa kokusingqongileyo, njl.njl., kusetyenziswa itekhnoloji ecocekileyo ukuvelisa izinto ezidibanisa imibala kunye ne-pigment.

Okokuqala, uphuhliso lokusetyenziswa kwezinto eziphakathi
Umfanekiso

Enyanisweni, uphuhliso lokusetyenziswa kwezinto eziphakathi luneendlela ezininzi, into ethile ephakathi esetyenziswa kwizinto zokudaya ebizwa ngokuba zii-dye intermediates, kwaye isetyenziswa kwii-pesticides, amayeza kunye nee-pesticides, ii-pharmaceutical intermediates. Izinto eziphakathi kufuneka zithathwe njengesebe leshishini leekhemikhali ezintle lilonke, akufuneki zahlulwe ngokungqongqo zibe zii-dyestuff intermediates, ii-pesticides intermediates, ii-pharmaceutical intermediates ngokweshishini, nto leyo eya kunciphisa umda wokusetyenziswa kwezinye izinto eziphakathi kwaye ichaphazele uphuhliso lwazo.

Uphando lwe-Fine chemical intermediates luphawulwa ziintlobo ngeentlobo ezahlukeneyo, ukongeza kwiintlobo ezimbalwa zemveliso enkulu kakhulu, uninzi lweentlobo ze-tonnage azinkulu kakhulu, kodwa inkqubo yokulungiselela idla ngokuba nzima, ibandakanya iimpendulo ezininzi zeeyunithi kunye nenkqubo yokwahlulahlula, imveliso ikwavelisa inani elikhulu "lenkunkuma ezintathu" ekufuneka iphathwe ngokufanelekileyo. Ke ngoko, kufuneka sibandakanyeke kuphando lwenkqubo yeemveliso zochungechunge kwaye silungiselele imveliso ye-intermediates ngokufanelekileyo ukuze sifumane iingenelo ezilungileyo zesikali.

Kwimeko yamazwe angaphandle, uphando kunye nemveliso yezinto eziphakathi zidla ngokugxininiswa ngokufanelekileyo ukuze kufezekiswe imveliso yochungechunge, iseti yezixhobo zemveliso inokuvelisa iintlobo ezininzi ukuya kwezilishumi elinesibini zezinto eziphakathi, uphando olunjalo kunye nemveliso ngophuhliso olupheleleyo, ukusetyenziswa kwetekhnoloji entsha kulula ukuyisebenzisa, kuya kufezekisa iziphumo eziphindwe kabini ngesiqingatha somzamo. Imeko yaseJapan inokuba yeyokubhekisela kuthi, imveliso yokuqala yezinto eziphakathi eJapan nayo isasazeke kakhulu, ukusukela ngeminyaka yoo-1960 kuye kwaba kasixhenxe ukulungisa, ukugxila.

Ngotshintsho nophuhliso, ishishini laseTshayina lokudaya nokufaka imibala lifikelele kwinqanaba eliphezulu ngokwezinga lemveliso, ubuchwepheshe kunye nenqanaba lezixhobo, elingenakuhlangabezana neemfuno zophuhliso lweshishini lokudaya nokufaka imibala lasekhaya kuphela, kodwa likwabonelela ngezixhobo ezisemgangathweni ngakumbi kumazwe angaphandle.

Izinto ezifunekayo ekuhlanganiseni izinto eziphakathi zifunyanwa kakhulu kwiimveliso zepetroleum kunye neekhemikhali zokupheka, uninzi lwazo ziyi-benzene, i-naphthalene, iikhompawundi ze-anthraquinone, kunye nezinye iikhompawundi ze-heterocyclic, kwaye ii-pigments ze-organic ezilungiselelwe ngeekhompawundi ze-heterocyclic ziyanda kwiminyaka yakutshanje. Ukongeza, i-phenanthrene, i-pyridine, i-oxygen fluorene, i-quinoline, i-indole, i-carbazole, uthotho lweekhompawundi ze-biphenyl, ezi zinto zintsonkothileyo ezisetyenziswa ekwenzeni iidayi, emva koko ukusetyenziswa kwezinto eziluhlaza zokwenziwa kuya kuba kubanzi ngakumbi kwaye kube yinto yonke.

Okwesibini, iimpembelelo zeekhemikhali ezisetyenziswa kakhulu ze-intermediates
Umfanekiso

Izinto ezisetyenziswa kakhulu ziya kucutshungulwa zibe yidayi (umbala) kushishino. Ezi zilandelayo ziindlela ezisetyenziswa kakhulu xa kusenziwa iikhemikhali.

(1) impendulo ye-sulfonation
(2) Impendulo ye-nitration
(3) impendulo ye-halogenation
(4) Ukunciphisa impendulo yokulungiselela i-amino
(5) I-Diazotization reaction (idla ngokuhamba ne-coupling reaction)
(6) impendulo ye-alkali fusion ukuze ithathe indawo yeqela le-sulfonic acid ibe yi-hydroxyl
(7) Impendulo ye-Acylation
(8) Impendulo ye-oxidation
(9) ukusabela kokufuma kunye ne-carbonation
(10) Impendulo ye-aromatization (ikakhulukazi i-amino)
(11) impendulo yokutshintshwa kwamaqela e-hydroxyl kunye nama-amino
(12) i-hydroxyl okanye i-amino hydrocarbonation reaction

Ngokwesakhiwo seringi eyintloko ye-aromatic ye-intermediates ezintle zeekhemikhali, i-intermediates inokwahlulwa ibe yi-aliphatic system, i-benzene system, i-naphthalene system, i-anthraquinone system, i-heterocyclic system kunye ne-thick ring system. Ilizwe lethu linokuvelisa i-benzene, i-naphthalene, i-anthraquinone, i-heterocyclic system, efana nokudaya, i-pigment intermediates ezingaphezu kwama-400, ngokusisiseko ukuhlangabezana neemfuno zophuhliso lweshishini lokudaya, i-pigment.
