Ukuphuhliswa kokusetyenziswa kwabaphakathi

Enyanisweni, ukusetyenziswa kwe-intermediates kuphuhliso oluneenkalo ezininzi, uhlobo oluthile lwe-intermediates olusetyenziswa kwiidayi ezibizwa ngokuba yi-dye intermediates, kwaye zisetyenziswe kwi-pesticides, amayeza, njalo njalo.Ikwabizwa ngokuba yi-pesticide, i-pharmaceutical intermediates.Ifanele ithathwe njengesebe leshishini lemichiza elilungileyo lilonke, akufuneki lahlulwe ngokungqongqo libe ngabaphakathi bedayi, abaphakathi bezinambuzane, abaphakathi bezinambuzane, abaphakathi bezinambuzane, abaphakathi bezinambuzane, abaphakathi bezinambuzane, abaphakathi kwezibulala-zinambuzane, abaphakathi kwezibulala-zinambuzane, abaphakathi bezinambuzane. , abangeneleli bokubulala izitshabalalisi, abangeneleli bokubulala izitshabalalisi, abangeneleli bokubulala izitshabalalisi, abangeneleli bokubulala izitshabalalisi, abangeneleli bokubulala izitshabalalisi, abangeneleli bokubulala izitshabalalisi, abangeneleli bokubulala izitshabalalisi, abangeneleli bokubulala izitshabalalisi, abangeneleli bezinambuzane, abaphakathi, abaphakathi abaphakathi, abaphakathi bamayeza ezinambuzane, abaphakathi kwezibulali zinambuzane, abaphakathi kwezibulala-zinambuzane, abaphakathi kwezibulala-zinambuzane, abaphakathi, abaphakathi bamayeza, abaza kunciphisa uluhlu lokusetyenziswa kwamanye aphakathi kwaye luchaphazelauphuhliso.

Uphando lwemichiza emihle ephakathi luphawulwa ngoluhlu olubanzi, ngaphandle kweentlobo ezimbalwa zesikali semveliso sikhulu kakhulu, uninzi lweentlobo zeetoni azikho zikhulu kakhulu, kodwa inkqubo yokulungiselela ihlala intsonkothile, ibandakanya ukuphendulwa kweyunithi kunye nokwahlula. ukuveliswa kweemali ezininzi "Inkunkuma emithathu" kufuneka iphathwe ngokufanelekileyo.Ke ngoko, kufuneka sibandakanyeke kuphando lwenkqubo yemveliso yeserial, umbutho ofanelekileyo wabaphakathi ukufumana impumelelo yokuvelisa.

Ukususela kwimeko yangaphandle, uphando kunye nokuveliswa kwabaphakathi bavame ukugxilwa ngokufanelekileyo ukuphumeza imveliso ye-serial.ezimbalwa ukuya kwishumi elinesibini iintlobo zabaphakathi, olo phando kunye nemveliso kulula ukuyiphumeza ngophuhliso olupheleleyo kunye nokwamkelwa kobuchwepheshe obutsha.Siza kufumana isiphumo esiphindwe kabini ngesiqingatha somzamo.Singabhekisela kwimeko yaseJapan, apho ukuveliswa kwabaphakathi kwakusetyenziselwa ukunatyiswa kakhulu, ukususela kwi-1960s.Iye yahlengahlengiswa yaza yagxininiswa izihlandlo ezisixhenxe.

Ngokusebenzisa inguqu kunye nophuhliso, idayi yaseTshayina kunye ne-pigment intermediates ishishini lifikelele kwinqanaba eliphezulu malunga nomlinganiselo wemveliso, iteknoloji kunye nenqanaba lesixhobo, elingenako ukuhlangabezana neemfuno zedayi yasekhaya kunye nophuhliso loshishino lwe-pigment, kodwa nokubonelela ngakumbi umgangatho weemveliso ze-intermediates amazwe angaphandle.

Iimathiriyeli ekrwada ezifunekayo ekuhlanganiseni iziphakathi zifumaneka ikakhulu kwiimveliso zepetroleum kunye neshishini lekhemikhali yokupheka, uninzi lwayo ibenzene, naphthalene, naphthalene, kunye nenaphthalene.Kwiminyaka yakutshanje, ii-pigments eziphilayo ezilungiselelwe ukusuka kwi-heterocyclic intermediates ziye zanda.Ukongeza, i-phenanthrene, i-pyridine, i-oxygen fluorene, i-quinoline, i-indole, i-carbazole, i-biphenyl series compounds, ezi zixhobo eziyinkimbinkimbi ezisetyenziselwa ukwenziwa kwedayi.Ukusetyenziswa kwemathiriyeli ekrwada yokwenziwa kuya kuxhaphaka kwaye kuxhaphake.

Iimpendulo zemichiza eziqhelekileyo ezisetyenziselwa abaphakathi

Ezona mpendulo zixhaphakileyo zekhemikhali ezisetyenziselwa ukusetyenzwa kwemathiriyeli ekrwada zibe ziphakathi kwishishini lokudaya (pigment) zezi zilandelayo.

(1) Ukusabela kweSulfon
(2) Ukusabela kwe-nitrification
(3) Ukusabela kweHalogenation
(4) Ukusabela kokunciphisa ukulungiselela i-amino
