| hoʻohana | hoʻohana nui ʻia no ka plastic, resin, rubber, paint, ink and pigment printing. hiki ke hoʻohana ʻia no ka paʻi ʻana i ka inika, ka pena, ka resin plastic kiʻekiʻe, ka paʻi puaʻa, nā huahana plastik palupalu, e like me ke kala |
| hana hana | he derivative me ka methyl substituent ma ka makua quinacridone, hiki i kona kaʻina hana ke kuhikuhi i ka quinacridone ʻulaʻula (CI Pigment Violet 19) kaʻina hana, a hiki ke hoʻololi ʻia ke kaʻina hana o ka aniline maka e P-toluidine, me kēia dibutyl succinate ke kaʻina hana synthesis, ʻehā mau ʻano synthetic no ke kuhikuhi. Hoʻomākaukau ʻia ka dibromoterephthalic acid mai ka p-xylene e ka bromination, oxidation, pane me ka amine a me ke apo pani. ʻO keʻano o ka hydroquinone e lawe ai kēia hana i ka aniline e like me ka mea maka, ma o ka hydroquinone a i ʻole p-benzoquinone carbonylation reaction, a laila hoʻohui ʻia me ka aniline synthesis, hoʻomākaukau i pani ʻia, akā ʻo ka hemahema nui o ke kaʻina hana ke kumu kūʻai kiʻekiʻe o ka hydroquinone. Ua hoʻomākaukau ʻia ka quinacridone Octa-hydrogenated e ka fusion reaction o 2.5-diamino-terephthalic acid me ka nui o ka cyclohexanone i mua o ka sulfuric acid, a laila ua synthesized e ka thermal dehydrogenation. Diketene ano like me diethyl succinate ala, diketene e ethyl chloride e hoomakaukau α-hydroacetoethyl Ester, a laila dimerization synthesis hydroquinone -2, 5-dicarboxylic acid ethyl ester hou condensation me aromatic amine, hoomakaukau e pani-loop oxidation. |
