Okumhlophe okumpunga kuya kokubomvu noma i-pulp. I-sodium m-aminobenzene sulfonate yatholwa ngokusabela kwe-sulfonation ye-nitrobenzene nokunciphisa. Isetshenziselwa ukwakhiwa kwamadayi e-azo kanye nemithi ephakathi kwemithi, esebenzayo, ene-asidi, ye-sulfide nabanye odayi.
I-METANIC ACIDUSAWOTI WESODIUM
英文 名 词: m-aminobenzenesulfonic ACID SODIUM SALT; I-SODIUM METANILATE.
Inombolo ye-CAS. : 1126-34-7
Inombolo ye-EINECS: 214-419-3 [1]
Ifomula yemolekyuli: C6H6NNaO3S
Isisindo se-molecule: 195.1734
Ukubukeka: Okumhlophe okumpunga kuya kukristalu obomvu okhanyayo noma okulufifi
Ikristalu elihle elimhlophe. Izinga lokushisa lokubola lekristalu elitholakala emanzini lingama-302 ~ 304 ℃.
I-Metanilic acidinokubukeka okubomvu okumpunga okuluhlaza okotshani njengokucwebezelayo noma okusaludaka
Isamba sokuqukethwe kwe-amino, % ≥60
Okuqukethwe, % ≥90
Okuqukethwe kwento engancibiliki kusoda, % ≤1.5
Isetshenziswa: isetshenziswa ekwakhiweni kodayi be-azo kanye nabaphakathi kwezemithi, abasebenzayo, i-asidi, i-sulfide nabanye odayi.
Umzila wenqubo yokukhiqiza: ukusabela kwe-sulfonation ye-nitrobenzene kanye ne-fuming sulfuric acid kwenziwa ku-115 ℃, futhi umkhiqizo wokusabela awuthathi hlangothi nge-alkali ewuketshezi, bese kuhlunga isisombululo se-sodium ye-m-nitrobenzene sulfonate. Isixazululo sancishiswa nge-iron shavings njenge-catalyst yokuthola i-m-aminobenzene sulfonate, futhi udaka lwensimbi lwasuswa ngokuhlunga. I-filtrate kwakuyisisombululo sikasawoti se-m-aminobenzene sulfonate. Engeza i-sulfuric acid embizeni yokukhipha i-asidi kuze kube iphepha lokuhlola elibomvu lase-Congo liphenduka libe luhlaza okwesibhakabhaka, futhi ugcine izinga lokushisa liku-70℃. Bese, i-m-aminobenzene sulfonate slurry itholwa ngokuhlunga kwe-centrifugation.
Ubuthi nokuvikelwa: lo mkhiqizo unobuthi kakhulu. Ukugwinya noma ukumunca esikhumbeni kungabangela ubuthi obunzima. Kodwa-ke, ubuthi bayo buncane kakhulu kune-aniline, futhi ngeke bubangele umphumela we-carcinogenic. Phakathi nenqubo yokukhiqiza, kufanele ivinjwe ngokuqinile ukuthi ingagqoki noma ifafaze isikhumba ngengozi, izinto zokukhiqiza kufanele zivalwe ukuze kuvinjelwe ukuvuza, futhi opharetha kufanele agqoke izinto zokuzivikela.
Ukupakisha nokugcina: gcina endaweni epholile, engenamoya neyomile, vimbela ukushisa, umswakama kanye nelanga. Gcina futhi uthuthe ngokuhambisana nemithethonqubo yezinto ezinobuthi.
