Uyafuna ukwazi okwengeziwe nge-Acid Red 73?

I-Acid Ebomvu 73eyaziwa nangokuthi i-Acid Brilliant Scarlet GR. Inombolo ye-CAS: 5413-75-2 I-Acid Ebomvu 73 ivame ukusetshenziswa njengodayi we-asidi embonini yendwangu. Ngokuvamile isetshenziselwa ukudaya izindwangu zoboya, usilika, nenayiloni. Iyaziwa ngombala wayo ogqamile futhi ohlala isikhathi eside, futhi ngokuvamile ilungiswa njengesixazululo ngaphambi kokuba isetshenziswe endwangu ngokusebenzisa amasu ahlukahlukene okudaya.

Izakhiwo zamakhemikhali impushana ebomvu ekhanyayo ephuzi. I-soluble emanzini iyisisombululo esibomvu, e-soluble otshwaleni ne-fibrin, engancibiliki ku-acetone, engancibiliki kwezinye izinyibilikisi eziphilayo. Uma i-sulfuric acid egxilile, ibomvu ngokunsomi, futhi ikhiqiza imvula ebomvu ebomvu ngemva kokuhlanjululwa; Uma i-nitric acid egxilile iluhlaza okwesibhakabhaka, iphenduka ibe nsundu yomnqumo ibe owolintshi. Isixazululo esinamanzi sanezelwa nge-concentrated hydrochloric acid ukuze kukhiqizwe imvula emnyama ngokubomvu ensundu, kanye noketshezi lwe-sodium hydroxide ukukhiqiza imvula ensundu ngokumnyama. Umbala we-copper ne-iron ions umnyama uma udaywa. Ukukhipha kuhle.

I-Acid ebomvu engu-73 ingudayi wokwenziwa, futhi indlela yawo yokukhiqiza inezinyathelo ezilandelayo:

1.Ukulungiswa kwempahla eluhlaza: kusetshenziswa izinhlanganisela ze-aniline njengezinto zokuqala, okuphuma ku-amine okunephunga elimnandi odayi kulungiswa ngokusabela kokwenziwa.

I-2.I-Compound synthesis: okuphuma ku-amine okunephunga elimnandi kusabela nge-sodium nitrite ngaphansi kwezimo ezine-asidi ukuze kukhiqizwe i-nitroso enamakha amine.

3.Ukusabela kokuhlangana: i-nitroso amine enuka kamnandi ihlanganiswe nenhlanganisela kanambambili ye-heterocyclic (njenge-naphthalene, i-pyridine, njll.) ukuze kukhiqizwe imikhiqizo yokuhlanganisa.

I-4.Ukuhlanganiswa kwezinhlanganisela ezizinzile: ngokulungisa izimo zokusabela, ezifana nezinga lokushisa, i-pH, njll., ukusabela kungafinyelela izinga lokuhlanganisa elifanele futhi kukhiqize imikhiqizo yokuhlanganisa ezinzile.

I-5.Crystallization and drying: isixazululo sedayi esitholwe ngokuhlanganisa sicwebezeliswa futhi somiswe ukuze sithole umkhiqizo wedayi we-asidi oqinile we-73.

Imboni yethu igxile ekukhiqizenii-asidi ebomvu 73,i-asidi orange II, i-asidi yegolide G, Rhodamine B, I-Malachite Green, I-Auramine O Conckanye nabanye odayi, imikhiqizo ifanele: iphepha ~ impepho ~ ithreyi lamaqanda
