  • p-Phenylenediamine CAS 106-50-3

incazelo emfushane:

I-p-Phenylenediamine (isiNgisi i-p-Phenylenediamine), eyaziwa nangokuthi i-Ursi D, ingenye yama-diamine anephunga elimnandi. Umkhiqizo omsulwa umhlophe ukuya kumakristalu e-lavender, aphenduka abe nsomi noma abe nsundu ngokumnyama lapho evezwe emoyeni.
umbala. Incibilika kancane emanzini abandayo, i-ethanol, i-ether, i-chloroform ne-benzene.
Ingasetshenziselwa ukulungisa amadayi e-azo, ama-polymers aphezulu we-molecular, futhi ingasetshenziswa futhi ukukhiqiza odayi boboya, ama-antioxidant erabha kanye nabathuthukisi bezithombe. Isetshenziselwa kakhulu ama-aramid, odayi be-azo, odayi besulfure, odayi be-asidi, futhi ingasetshenziswa njengoboya abamnyama D. Ukukhiqizwa kwe-Mao Pi Black DB, i-Mao Pi Brown N2, kanye ne-Chemicalbook rubber antioxidants DNP, DOP, ne-MB. Ibuye isetshenziswe njengempahla eluhlaza ochungechungeni lwedayi yezinwele zezimonyo i-Ursi D, inhibitor ye-polymerization kaphethiloli kanye nonjiniyela. Njengodayi wamakhemikhali, i-p-phenylenediamine okwamanje ivunyelwe ukusetshenziswa ekukhiqizeni amadayi ezinwele, kodwa kunemikhawulo ecacile mayelana nenani lokusetshenziswa.
Itholakala ngokunciphisa i-p-nitroaniline nge-iron powder endaweni ene-acidic. Faka i-iron powder ku-hydrochloric acid, uyishise ibe ngu-90 ° C, bese wengeza i-p-nitroaniline ngenkathi uvuselela. Ngemuva kokuthi ukwengeza sekuqediwe, phendula ku-95-100 ° C ngo-0.5h, bese wengeza i-hydrochloric acid egxilile ngendlela ehlayo ukuze uqedele ukusabela kwe-Chemicalbook yokunciphisa. Ngemuva kokupholisa, nciphisa ngesisombululo se-sodium carbonate esine-saturated ku-pH 7-8, ubilise futhi uhlunge ngenkathi kushisa, bese ugeza ikhekhe lokuhlunga ngamanzi ashisayo. Hlanganisa i-filtrate noketshezi lokuwasha, gxila ngaphansi kwengcindezi encishisiwe, ucwebeze ngokupholisa noma ukhiphe ngaphansi kwengcindezi encishisiwe ukuze uthole i-p-phenylenediamine ngesivuno esingu-95%.

    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Isingeniso somkhiqizo

    I-N-methylmorpholine iyingxenye ebalulekile yamakhemikhali ephilayo. Kuyi-solvent enhle kakhulu, i-emulsifier, i-corrosion inhibitor, i-polyurethane foam catalyst, futhi ingasetshenziswa njengesibulala-zinambuzane esimaphakathi. Izindlela zokuhlanganisa ze-Chemicalbook ikakhulukazi zifaka indlela ye-N-methylation esebenzisa i-morpholine njengempahla eluhlaza, indlela ye-cyclization isebenzisa i-diethanolamine njengempahla eluhlaza, indlela ye-cyclization isebenzisa i-diethanolamine njengento eluhlaza, kanye nendlela yokuhlanganisa isebenzisa i-dichloroethane njengempahla eluhlaza, njll.

    Inkambu yohlelo lokusebenza

    I-N-Methylmorpholine iyi-solvent enhle kakhulu yamadayi, i-tyrosol, i-wax ne-shellac, njll.; i-extractant, i-stabilizer yama-hydrocarbon ane-chlorine, ama-reagents okuhlaziya, ama-catalysts, ama-corrosion inhibitors; ibuye isetshenziswe njenge-accelerator yerabha namanye amakhemikhali amahle I-Synthesis; Ibuye isetshenziswe njenge-polyurethane catalyst, i-catalyst yokuhlanganiswa kwe-ampicillin ne-hydroxybenzyl penicillin, njll.

    Iphakathi nendawo esetshenziswa kabanzi futhi ingasetshenziselwa ukulungisa amadayi e-azo nama-polymer aphezulu wamangqamuzana. Ingase futhi isetshenziselwe ukukhiqiza odayi boboya, ama-antioxidant erabha kanye nabathuthukisi bezithombe. Ngaphezu kwalokho, i-p-phenylenediamine nayo ivame ukusetshenziselwa ukuhlola i-iron ne-Copper sensitive reagent.
