Kodi mukufuna kudziwa zambiri za Acid Red 73?

Acid Red 73amadziwikanso kuti Acid Brilliant Scarlet GR. Nambala ya CAS: 5413-75-2 Acid Red 73 imagwiritsidwa ntchito ngati utoto wa asidi mumakampani opanga nsalu. Nthawi zambiri amagwiritsidwa ntchito popaka utoto wa ubweya, silika, ndi nayiloni. Amadziwika ndi mtundu wake wowoneka bwino komanso wokhalitsa, ndipo nthawi zambiri amakonzedwa ngati yankho asanayambe kugwiritsidwa ntchito pa nsalu pogwiritsa ntchito njira zosiyanasiyana zopaka utoto.

Mankhwala katundu chikasu kuwala ufa wofiira. Kusungunuka m'madzi ndi njira yofiira, yosungunuka mu mowa ndi fibrin, insoluble mu acetone, insoluble mu organic solvents. Pankhani ya sulfuric acid yokhazikika, imakhala yofiirira, ndipo imatulutsa mpweya wofiirira pambuyo pa dilution; Asidi wa nitric akakhala wa buluu, amasanduka bulauni wa azitona kukhala lalanje. Njira yamadzimadzi idawonjezedwa ndi hydrochloric acid kuti ipangitse mpweya wofiyira wofiirira, ndimadzimadzi a sodium hydroxide kuti apange mpweya woderapo. Mtundu wa ma ayoni amkuwa ndi chitsulo ndi wakuda mukadaya. Kutulutsa ndikwabwino.

Acid red 73 ndi utoto wopangira, ndipo njira yake yopangira imakhala ndi izi:

1.Kukonzekera kwazinthu zopangira: kugwiritsa ntchito mankhwala a aniline monga zipangizo zoyambira, zonunkhira za amine zochokera ku utoto zimakonzedwa ndi kupanga.

2.Compound kaphatikizidwe: onunkhira amine zotumphukira amachita ndi sodium nitrite pansi acidic mikhalidwe kupanga nitroso onunkhira amine.

3.Coupling reaction: nitroso amine onunkhira amaphatikizidwa ndi mankhwala a binary heterocyclic (monga naphthalene, pyridine, etc.) kuti apange zinthu zolumikizirana.

4.Synthesis ya mankhwala khola: ndi kusintha zinthu anachita, monga kutentha, pH, etc., anachita akhoza kufika abwino lumikiza digiri ndi kupanga khola lumikiza mankhwala.

5.Crystallization ndi kuyanika: njira yothetsera utoto yomwe imapangidwa ndi kaphatikizidwe imapangidwa ndi crystallized ndikuuma kuti ipeze mankhwala ofiira a asidi ofiira 73.

Fakitale yathu imakhazikika pakupanga kwaasidi wofiira 73,asidi lalanje II, asidi golide G, Rhodamine B, Malachite Green, Auramine O Concndi utoto wina, mankhwalawo ndi oyenera: pepala ~ zofukiza ~ thireyi ya dzira
