Acetic acid

Kufotokozera kwaifupi:

Ndi anyezi acic acid, gawo lalikulu la viniga. Mafuta a acehydrous acetic acetic acid (glathic acetic acid) ndi utoto wamadzi wopanda utoto, yankho lake la madzi ndi lofooka, ndipo ndi lamphamvu ku zitsulo.

Kapangidwe ka acetil ya acetic acid kumawonetsa kuti mamolekyulu amalumikizidwa kukhala ochepera (omwe amadziwika kuti ndi ma acid apamwamba) Kulemera kwa madoletala mochulukitsa pakuzizira kwa X-ray. Pamene acetic acid itasungunuka ndi madzi, maofesi a hydrogen pakati pa oyendetsa amachoka mwachangu. Macitidi ena a carboxyylic acid amawonetsa kusokoneza.

Kugwiritsa Ntchito Mafakitale

1. Acetic acid ndi mankhwala ambiri mankhwala, ndi amodzi mwa acid. Zimagwiritsidwa ntchito makamaka popanga acematic terhydride, aceaute ndi cellulose. Polyvinyl acetate amatha kupangidwa m'mafilimu ndi zomata, komanso ndizomwe zimapangitsa kuti zitsulo zikhale zopangidwa. Celluluse acetate imagwiritsidwa ntchito kupanga mavidiyo a rayon ndi Month.

2. Ester ya acetika imapangidwa ndi mowa wochepa ndi wosungunulira bwino, wogwiritsidwa ntchito kwambiri pakompyuta ya utoto. Chifukwa acetic acid imasungunuka kwambiri, imagwiritsidwanso ntchito ngati zosungunulira (mwachitsanzo, kuti ma okosi a P-xlene kuti atulutse terephthalic acid).

4. Popanga mahema, monga manganese, sodium, sodium, aluminiyamu, zinct, zomwe zimagwiritsidwa ntchito kwambiri, zojambulajambula zokutira zojambula; Kugawika Acetate ndi utoto upangire utoto woyera; Chigawo cha Tetraacetate ndi chophatikizika cha organisas (mwachitsanzo, chotsogolera Tretacetate chitha kugwiritsidwa ntchito ngati wothandizira wambiri wa oxading, amapereka gwero la mankhwala otsogolera acetoxy, etc.).

Kugwiritsa Ntchito Chakudya

Pakugulitsa zakudya, acetic acid amagwiritsidwa ntchito ngati acidifier, zonunkhira pokonzanso viniga, ma acitic acid amasungunuka mpaka 4-5% ndi madzi, ndipo mankhwala onunkhira amawonjezeredwa. Kukoma kumafanana ndi ku viniga kwa utoto, ndipo nthawi yopanga ndi yochepa ndipo mtengo ndiwotsika mtengo. Monga wowawasa, itha kugwiritsidwa ntchito popanga zokometsera, kukonzekera viniga, zamzitini, zakudya ndi tchizi, molingana ndi zofuna zogwiritsa ntchito zoyenera. Itha kufotokozanso za zonunkhira za ofukiza, kuchuluka kwa ntchito ndi 0.1 ~ 0.3 g / kg.
