Pigment Liab 122 CAS 980-26-7 / 16043-40-6
| siv | yog tsuas yog siv rau yas, cob, roj hmab, xim, number case thiab pigment printing. tuaj yeem siv rau luam ntawv number case, xim, qib siab yas resin, pigment luam ntawv, cov khoom yas mos, xws li xim |
| txoj kev tsim khoom | yog ib tug derivative nrog ib tug methyl hloov nyob rau hauv cov niam txiv quinacridone, nws cov txheej txheem ntau lawm yuav xa mus rau quinacridone liab (CI Pigment Violet 19) txheej txheem ntau lawm, thiab cov txheej txheem ntawm aniline raw cov ntaub ntawv yuav hloov los ntawm P-toluidine, ntxiv rau no dibutyl succinate. txheej txheem synthesis, muaj plaub txoj kev siv hluavtaws siv. Dibromoterephthalic acid yog npaj los ntawm p-xylene los ntawm bromination, oxidation, cov tshuaj tiv thaiv nrog amine thiab lub nplhaib kaw. Hydroquinone txoj kev no yuav siv aniline li raw khoom, los ntawm hydroquinone los yog p-benzoquinone carbonylation cov tshuaj tiv thaiv, thiab ces fused nrog aniline synthesis, kaw-voj npaj, tab sis lub ntsiab disadvantage ntawm cov txheej txheem yog tus nqi siab ntawm hydroquinone. Octa-hydrogenated quinacridone tau npaj los ntawm fusion cov tshuaj tiv thaiv ntawm 2.5-diamino-terephthalic acid nrog ntau tshaj cyclohexanone nyob rau hauv lub xub ntiag ntawm sulfuric acid, thiab ces yog synthesized los ntawm thermal dehydrogenation. Diketene txoj kev zoo ib yam li txoj kev diethyl succinate, diketene los ntawm ethyl chloride los npaj α-hydroacetoethyl Ester, thiab tom qab ntawd dimerization synthesis hydroquinone -2, 5-dicarboxylic acid ethyl ester ntxiv condensation nrog aromatic amine, npaj los ntawm kaw-voj oxidation. |
