Mea Hana Kumukūʻai Maikaʻi Glacial Acetic Acid CAS: 64-19-7

1. Loaʻa ka waikawa acetic i loko o ka vīnega. Hana ʻia ia i ka distillation luku o ka lāʻau. Loaʻa iā ia ka hoʻohana nui ʻana i ka ʻoihana kemika. Hoʻohana ʻia ia i ka hana ʻana o ka cellulose acetate, acetate rayon, a me nā hui acetate a me acetyl like ʻole; ma ke ʻano he mea hoʻoheheʻe no nā gums, nā aila, a me nā resins; ma ke ʻano he mea mālama meaʻai i ka paʻi ʻana a me ka hoʻoluʻu ʻana; a ma ka hana ʻana o nā mea ola.
2. He kemika ʻoihana koʻikoʻi ka waikawa acetic. ʻO ka hopena o ka waikawa acetic me nā hui hydroxyl, ʻoi aku hoʻi nā waiʻona, e hopena i ka hoʻokumu ʻia ʻana o nā esters acetate. ʻO ka hoʻohana nui ʻana o ka waikawa acetic ma ka hana ʻana o ka vinyl acetate. Hiki ke hana ʻia ka vinyl acetate ma o ka hopena o ka acetylene a me ka waikawa acetic. Hana ʻia nō hoʻi ia mai ka ethylene a me ka waikawa acetic. Hoʻohuihui ʻia ka vinyl acetate i loko o ka polyvinyl acetate (PVA), kahi i hoʻohana ʻia i ka hana ʻana o nā fibers, nā kiʻiʻoniʻoni, nā mea hoʻopili, a me nā pena latex.
ʻO ka cellulose acetate, ka mea i hoʻohana ʻia i nā lole a me nā kiʻiʻoniʻoni kiʻi, ua hana ʻia ma ka hoʻopili ʻana i ka cellulose me ka waikawa acetic a me ka acetic anhydride i ke alo o ka waikawa sulfuric. Hoʻohana ʻia nā esters ʻē aʻe o ka waikawa acetic, e like me ka ethyl acetate a me ka propyl acetate, i nā ʻano hana like ʻole.
Hoʻohana ʻia ka waikawa acetic e hana i ka polyethylene terephthalate plastic (PET). Hoʻohana ʻia ka waikawa acetic e hana i nā lāʻau lapaʻau.
3. ʻO ka Glacial Acetic Acid kahi acidulant he wai moakaka, ʻaʻohe kala nona ka ʻono waikawa ke hoʻokahe ʻia me ka wai. He 99.5% a ʻoi aku paha kona maʻemaʻe a hoʻopili ʻia ma 17°c. Hoʻohana ʻia ia i loko o nā ʻaʻahu salakeke i ke ʻano hoʻokahe ʻia e hāʻawi i ka waikawa acetic e pono ai. Hoʻohana ʻia ia ma ke ʻano he mea mālama, acidulant, a me ka mea ʻono. Ua kapa ʻia hoʻi ʻo ia he acetic acid, glacial.
4. Hoʻohana ʻia ka waikawa acetic ma ke ʻano he vīnega papaʻaina, ma ke ʻano he mea mālama a ma ke ʻano he waena i ka ʻoihana kemika, e like me nā olonā acetate, acetates, acetonitrile, nā lāʻau lapaʻau, nā mea ʻala, nā mea palupalu, nā dyes (indigo) etc. Pepa ʻIkepili Huahana.
5. Hoʻohana ʻia ia i nā titrations acid-base aqueous a me non-aqueous.
6. Hana ʻana i nā ʻano acetates like ʻole, nā hui acetyl, cellulose acetate, acetate rayon, plastics a me ka rubber i ka tanning; e like me ka wai ʻawaʻawa no ka holoi lole; ka paʻi ʻana i ka calico a me ka hoʻoluʻu ʻana i ka silika; e like me ka acidulant a me ka preservative i nā meaʻai; solvent no nā gums, resins, volatile oils a me nā mea ʻē aʻe he nui. Hoʻohana nui ʻia i nā syntheses organik kalepa. Kōkua lāʻau lapaʻau (acidifier).
