| hanyar samarwa | wani abin da aka samo asali ne tare da maye gurbin methyl akan iyayen quinacridone, tsarin samar da shi zai iya komawa zuwa tsarin samar da quinacridone ja (CI Pigment Violet 19), kuma ana iya maye gurbin tsarin albarkatun aniline ta hanyar P-toluidine, ban da wannan dibutyl succinate. Tsarin kira, akwai hanyoyi guda huɗu na roba don tunani. An shirya Dibromoterephthalic acid daga p-xylene ta hanyar bromination, oxidation, amsawa tare da amine da ƙulli zobe. Hanyar Hydroquinone wannan tsari yana ɗaukar aniline azaman albarkatun ƙasa, ta hanyar hydroquinone ko p-benzoquinone carbonylation reaction, sa'an nan kuma an haɗa shi tare da haɗin aniline, shirye-shiryen rufewa, amma babban rashin amfani da tsarin shine babban farashin hydroquinone. Octa-hydrogenated quinacridone an shirya shi ta hanyar fusion reaction na 2.5-diamino-terephthalic acid tare da wuce haddi na cyclohexanone a gaban sulfuric acid, sa'an nan kuma an haɗa shi ta thermal dehydrogenation. Hanyar Diketene yayi kama da hanyar diethyl succinate, diketene ta ethyl chloride don shirya α-hydroacetoethyl Ester, sa'an nan kuma dimerization kira hydroquinone -2, 5-dicarboxylic acid ethyl ester yana kara haɓakawa tare da amine aromatic, shirye-shirye ta hanyar rufe-madauki oxidation. |
