| njira yopanga | ndi chochokera ndi methyl substituent pa kholo la quinacridone, kupanga kwake kungatanthauze kupanga kwa quinacridone red (CI Pigment Violet 19), ndipo njira ya aniline zopangira zitha kusinthidwa ndi P-toluidine, kuphatikiza pa dibutyl succinate iyi. kaphatikizidwe ndondomeko, pali njira zinayi zopangira zofotokozera. Dibromoterephthalic acid imakonzedwa kuchokera ku p-xylene ndi bromination, oxidation, reaction ndi amine ndi kutseka kwa mphete. Njira ya Hydroquinone ndondomekoyi imatenga aniline ngati zopangira, kupyolera mu hydroquinone kapena p-benzoquinone carbonylation reaction, ndiyeno imasakanikirana ndi kaphatikizidwe ka aniline, kukonzekera kotsekedwa, koma kuipa kwakukulu kwa ndondomekoyi ndi mtengo wapamwamba wa hydroquinone. Octa-hydrogenated quinacridone linakonzedwa ndi maphatikizidwe anachita 2.5-diamino-terephthalic asidi ndi owonjezera cyclohexanone pamaso pa sulfuric acid, ndiyeno anali apanga ndi matenthedwe dehydrogenation. Njira ya Diketene ndi yofanana ndi njira ya diethyl succinate, yopangidwa ndi ethyl chloride yokonzekera α-hydroacetoethyl Ester, ndiyeno dimerization synthesis hydroquinone -2, 5-dicarboxylic acid ethyl ester yowonjezera condensation ndi amine onunkhira, kukonzekera ndi kutsekedwa kwa okosijeni. |
Lembani uthenga wanu apa ndikutumiza kwa ife
