Chinsinsi cha glacial acetic acid

Koyeraglacial asidi asidi, ndiye kuti, anhydrous acetic acid, acetic acid ndi imodzi mwazinthu zofunika kwambiri za organic, organic mankhwala. Zimakhazikika mu ayezi pamtunda wochepa ndipo nthawi zambiri zimatchedwaglacial asidi asidi. Kuzizira ndi 16.6° C (62° F), ndipo itatha kukhazikika, imakhala kristalo wopanda mtundu. Madzi ake amadzimadzi ndi ofooka acidic komanso owononga kwambiri, ndipo amawononga kwambiri zitsulo. Nthunziyi imakwiyitsa maso ndi mphuno. Kotero, ndi ntchito zotani zomwe zimagwiritsidwa ntchito glacial asidi asidim'mafakitale osiyanasiyana?

Choyamba, glacial acetic acid mafakitale ntchito

1. Amagwiritsidwa ntchito popanga utoto ndi inki.

2. M'makampani azakudya, amagwiritsidwa ntchito ngati acidity regulator, acidifier, pickling agent, flavor enhancer, zonunkhira ndi zina zotero. Komanso ndi mankhwala abwino oletsa tizilombo toyambitsa matenda, makamaka chifukwa cha mphamvu yake yochepetsera pH pansi pa pH yofunikira kuti tizilombo toyambitsa matenda tizikula bwino.

3. Amagwiritsidwa ntchito pamakampani opanga mphira ndi mapulasitiki. Amagwiritsidwa ntchito ngati zosungunulira ndi zoyambira zopangira ma polima ambiri ofunikira (monga PVA, PET, etc.) mumakampani amphira ndi mapulasitiki.

4. Amagwiritsidwa ntchito ngati chiyambi cha utoto ndi zomatira.

5. Glacial acetic acid imagwiranso ntchito yofunika kwambiri pakuchapira, makamaka poletsa kutayika kwa utoto pa zovala, imachotsa madontho mwamphamvu, ndipo imatha kusokoneza pH, koteroglacial asidi asidi ndizodziwika kwambiri pakuchapira. Mukamagwiritsa ntchito, iyenera kugwiritsidwa ntchito molingana ndi malangizo ena, ndipo sungagwiritse ntchito mwachimbulimbuliglacial asidi asidi.

Chachiwiri,glacial asidi asidi kugwiritsa ntchito mankhwala

1. Kwa kaphatikizidwe ka cellulose acetate. Cellulose acetate imagwiritsidwa ntchito mufilimu yojambula ndi nsalu. Asanapangidwe filimu ya cellulose acetate, filimu yojambula zithunzi inkapangidwa kuchokera ku nitrate ndipo panali zambiri zokhudzana ndi chitetezo.

2. Ntchito monga zosungunulira kwa synthesis wa asidi terephthalic. P-xylene ndi oxidized kukhala terephthalic acid. Terephthalic acid imagwiritsidwa ntchito popanga PET ndipo imagwiritsidwa ntchito kwambiri popanga mabotolo apulasitiki.

3. Amagwiritsidwa ntchito kwambiri popanga ma esters pochita ndi zakumwa zosiyanasiyana. Zochokera ku Acetate zimagwiritsidwa ntchito kwambiri ngati zowonjezera chakudya.

4. Amagwiritsidwa ntchito popanga vinyl acetate monomer. Monomer ndiye amatha kupangidwa polima kuti apange poly (vinyl acetate), yomwe imadziwikanso kuti PVA.

5. Ntchito monga zosungunulira ambiri organic chothandizira zimachitikira.

6. Amagwiritsidwa ntchito ngati sikelo ndi chochotsa dzimbiri. Litiasidi asidiamachitira ndi madzi, sikelo hisses ndi thovu kutha, kuswa izo kuchokera olimba kukhala madzi kuti mosavuta kuchotsedwa.
