Kodi mukufuna kudziwa zambiri za Acid Red 73?

Asidi Wofiira 73Amadziwikanso kuti Acid Brilliant Scarlet GR. Nambala ya CAS: 5413-75-2 Acid Red 73 imagwiritsidwa ntchito kwambiri ngati utoto wa asidi m'makampani opanga nsalu. Nthawi zambiri imagwiritsidwa ntchito kupenta ubweya, silika, ndi nsalu za nayiloni. Imadziwika ndi mtundu wake wowala komanso wokhalitsa, ndipo nthawi zambiri imakonzedwa ngati yankho lisanapakedwe pa nsaluyo kudzera munjira zosiyanasiyana zopenta.

Kapangidwe ka mankhwala achikasu ndi ufa wofiira wopepuka. Sungunuka m'madzi ndi yankho lofiira, losungunuka mu mowa ndi fibrin, losasungunuka mu acetone, losasungunuka mu zinthu zina zachilengedwe. Ngati asidi wokhuthala wa sulfuric acid, amakhala wofiirira wofiira, ndipo amapanga mawanga ofiirira ofiira pambuyo posungunuka; asidi wokhuthala wa nitric acid akakhala wabuluu, amasanduka bulauni wa azitona kukhala lalanje. Madzi oundanawo amawonjezeredwa ndi hydrochloric acid wokhuthala kuti apange mawanga ofiirira ofiira, ndipo madzi a sodium hydroxide kuti apange mawanga ofiirira ofiira. Mtundu wa ma ayoni amkuwa ndi achitsulo umakhala wakuda akapakidwa utoto. Kutuluka kwa madzi ndi kwabwino.

Asidi wofiira 73 ndi utoto wopangidwa ndi zinthu zopangidwa, ndipo njira yake yopangira ili ndi njira zotsatirazi:

1. Kukonzekera zinthu zosaphika: pogwiritsa ntchito mankhwala a aniline ngati zinthu zoyambira, utoto wa amine wonunkhira umakonzedwa pogwiritsa ntchito njira yopangira.

2. Kupanga kwa compound: zotumphukira za amine zimakumana ndi sodium nitrite pansi pa acidic kuti zipange amine ya nitroso aromatic.

3. Kugwirizana: nitroso aromatic amine imalumikizidwa ndi ma binary heterocyclic compounds (monga naphthalene, pyridine, ndi zina zotero) kuti ipange zinthu zolumikizira.

4. Kupanga mankhwala okhazikika: mwa kusintha momwe zinthu zimachitikira, monga kutentha, pH, ndi zina zotero, zomwe zimachitika zimatha kufika pamlingo woyenera wa coupling ndikupanga zinthu zokhazikika zolumikizira.

5. Kupaka utoto ndi kuumitsa: njira yopangira utoto yomwe imapezeka pogwiritsa ntchito njira yopangira utoto imapangidwa ndi kristalo ndikuumitsidwa kuti ipange utoto wofiira wokhazikika wa asidi 73.
