Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Pigment Red 122 CAS 980-26-7/16043-40-6

isebenzisa isetshenziswa kakhulu ukuphrinta ipulasitiki, inhlaka, irabha, upende, uyinki nombala.
ingasetshenziselwa ukuphrinta uyinki, upende, i-plastic resin ephezulu, ukuphrinta umbala, imikhiqizo yepulasitiki ethambile, njengombala
indlela yokukhiqiza iwukuphuma okune-methyl substituent kumzali we-quinacridone, inqubo yayo yokukhiqiza ingabhekisa kunqubo yokukhiqiza ebomvu ye-quinacridone (CI Pigment Violet 19), futhi inqubo yezinto zokusetshenziswa ze-aniline ingathathelwa indawo yi-P-toluidine, ngaphezu kwale succinate ye-dibutyl. inqubo synthesis, kunezindlela zokwenziwa ezine inkomba. I-Dibromoterephthalic acid ilungiswa kusuka ku-p-xylene nge-bromination, i-oxidation, ukusabela nge-amine nokuvalwa kwendandatho. Indlela ye-Hydroquinone le nqubo ithatha i-aniline njengento eluhlaza, ngokusebenzisa i-hydroquinone noma i-p-benzoquinone carbonylation reaction, bese ihlanganiswa ne-aniline synthesis, ukulungiswa kwe-loop evaliwe, kodwa okubi okuyinhloko kwenqubo yintengo ephezulu ye-hydroquinone. I-quinacridone ye-Octa-hydrogenated yalungiselelwa ukusabela kwe-fusion ye-2.5-diamino-terephthalic acid ene-cyclohexanone eyeqile phambi kwe-sulfuric acid, bese ihlanganiswa nge-thermal dehydrogenation. Indlela ye-Diketene ifana nendlela ye-diethyl succinate, i-etane by ethyl chloride yokulungisa i-α-hydroacetoethyl Ester, bese kuba i-dimerization synthesis hydroquinone -2, 5-dicarboxylic acid ethyl ester eminye ukujiya nge-amine enuka kamnandi, ukulungiswa nge-oxidation evaliwe.
