Kuyini i-2-Methyl anthraquinone?

Amakristalu aphuzi. Ayincibiliki emanzini, incibilika ku-ethanol, i-ether, i-benzene kanye ne-ethyl acetate. I-2-Methyl anthraquinone inenani elikhulu lezimboni. Ayisetshenziswa nje kuphela njenge-intermediate yamakhemikhali yokwenza amadayi amnyama asezingeni eliphezulu, kodwa futhi iyisengezo esisebenzayo sokwenza iphepha. Iphinde isetshenziswe kabanzi kwezokwelapha, ezibulala-zinambuzane nakwezinye izici eziningi. I-2-Methyl anthraquinone evame kakhulu yi-2-Methyl anthraquinone, njll., kanti i-2-Methyl anthraquinone ingashintshwa ngokwezidingo ezahlukene zokuhlanganisa ama-compounds aqondiwe.

Isicelo

1. Ngokuphathelene nodayi, i-2-methylanthraquinone iqala ngokufakwa i-chlorine noma i-nitrate ukuze kukhiqizwe udayi we-anthraquinone ohlukahlukene. Izibalo zibonisa ukuthi kunamakhulu odayi we-anthraquinone anenani elikhulu lokuhweba.

2. Enqubweni yokwenza iphepha, i-2-methylanthraquinone iyisithako esisebenza kahle kakhulu. Ingangena ngaphakathi kwezingcezu zokhuni bese yehliswa ibe yi-2-methylanthraquinone hydroquinone, engazinzile futhi eqiniswa kalula. Phakathi nalo mjikelezo we-redox, izingxenye ezingcezu zokhuni ziyaqiniswa, okwandisa ukusabela futhi kuthuthukise ukusebenza kahle kwe-pulping.

3. Kwezokwelapha, ama-alkyl anthraquinone nawo anenani elikhulu kakhulu kwezokwelapha. Ngokusho kocwaningo lwamanje, imiphumela yokubulala amangqamuzana e-anthraquinone yokulwa namagciwane, ukuvuvukala, ukulwa namagciwane kanye nokubulala amangqamuzana esimila ihlala ihlolwa, futhi eminye isetshenziswa emsebenzini wangempela wokuvimbela izifo.
