| mokhoa oa tlhahiso | ke derivative e nang le methyl substituent ho motsoali oa quinacridone, ts'ebetso ea eona ea tlhahiso e ka bolela ts'ebetso ea tlhahiso ea quinacridone e khubelu (CI Pigment Violet 19), mme ts'ebetso ea lisebelisoa tse tala tsa aniline e ka nkeloa sebaka ke P-toluidine, ntle le dibutyl succinate. mokhoa oa ho kopanya, ho na le mekhoa e mene ea maiketsetso bakeng sa litšupiso. Dibromoterephthalic acid e lokiselitsoe ho tloha p-xylene ka bromination, oxidation, karabelo ka amine le ho koala lesale. Mokhoa oa Hydroquinone ts'ebetso ena e nka aniline e le thepa e tala, ka hydroquinone kapa p-benzoquinone carbonylation reaction, ebe e kopanngoa le aniline synthesis, ho lokisoa ha loop e koetsoeng, empa mofokoli o moholo oa ts'ebetso ke theko e phahameng ea hydroquinone. Octa-hydrogenated quinacridone e ile ea lokisoa ke karabelo ea fusion ea 2.5-diamino-terephthalic acid e nang le cyclohexanone e feteletseng ka boteng ba sulfuric acid, ebe e entsoe ka thermal dehydrogenation. Mokhoa oa Diketene o tšoana le mokhoa oa diethyl succinate, mohatone ka ethyl chloride ho lokisa α-hydroacetoethyl Ester, ebe dimerization synthesis hydroquinone -2, 5-dicarboxylic acid ethyl ester e eketsehileng condensation le amine e nkhang hamonate, ho lokisoa ka ho koala-loop oxidation. |
