Acetic acid, wai waihoʻoluʻu ʻole, loaʻa kahi ʻala ʻala ikaika.ʻO ka helu hoʻoheheʻe o ka waika acetic he 16.6 ℃, ʻo ka helu hoʻolapalapa ʻo 117.9 ℃, ʻo ka pānaʻi pili he 1.0492 (20/4 ℃), a ʻo ka index refractive he 1.3716.Hiki i ka ʻakika acetic maʻemaʻe ke hana i kahi paʻa like me ka hau ma lalo o 16.6 °C, no laila ua kapa pinepine ʻia ʻo ia ka glacial acetic acid.ʻO ka waika Acetic kahi mea koʻikoʻi koʻikoʻi kemika, hoʻohana nui ʻia e hoʻomākaukau i ka vinyl acetate monomer (VAM), cellulose acetate, acetic anhydride, terephthalic acid, chloroacetic acid, polyvinyl alcohol, acetate a me metal acetate.
Hoʻohana nui ʻia ka Acetic acid i ka synthesis organik kumu, lāʻau lapaʻau, pesticides, paʻi a me ke kala, textiles, meaʻai, pena, adhesives a me nā ʻoihana ʻē aʻe.ʻO ka ʻakika acetic kahi mea waiwai nui.ʻO nā ʻenehana hana ʻenehana o ka acetic acid ka mea nui: methanol carbonylation method, acetaldehyde oxidation, ethylene direct oxidation a me ka ʻaila hinu māmā.Ma waena o lākou, ʻo ka methanol carbonylation ka ʻenehana i hoʻohana nui ʻia, ʻoi aku ma mua o 60% o ka nui o ka mana hana honua, a ke ulu nei kēia ʻano.
Ke hōʻike nei ka mana o ka honua acetic acid i ka piʻi ʻana, a e ulu pū ana kāna koi honua ma ka awelika makahiki ma kahi o 5% i nā makahiki e hiki mai ana, kahi o 94% o ka mana hana acetic acid hou o ka honua. ʻO Asia, a ʻo ka ʻāina ʻo ʻAsia kekahi i ka wā e hiki mai ana.Ke alakaʻi nei i ka ulu wikiwiki o ka noi mākeke honua i loko o ʻelima mau makahiki.
palapala noi:
1. Acetic acid derivatives: hoʻohana nui ʻia i ka synthesis o ka acetic anhydride, acetate, terephthalic acid, vinyl acetate / polyvinyl alcohol, cellulose acetate, ketene, chloroacetic acid, haloacetic acid, etc.;
2. ʻO ka lāʻau lapaʻau: Hoʻohana ʻia ka Acetic acid ma ke ʻano he solvent a me ka lāʻau lapaʻau, hoʻohana nui ʻia i ka hana ʻana o ka penicillin G potassium, penicillin G sodium, procaine penicillin, nā papa antipyretic, sulfadiazine, sulfamethoxazole, norfloxacin, ciprofloxacin Floxacin, acetylsalicylic acid. prednisone, caffeine, etc.;
3. Nā mea waena like ʻole: acetate, sodium diacetate, peracetic acid, etc.;
4. Pigments a me ka textile paʻi a me ka waihoʻoluʻu: hoʻohana nui ʻia no ka hana ʻana i nā disperse dyes a me vat dyes, a me ka paʻi textile a me ka hana hoʻoluʻu;
5. ʻO ka ammonia Synthetic: i ke ʻano o ka cupric acetate ammonia wai, hoʻohana ʻia e like me ka hoʻomaʻemaʻe ʻana o ke kinoea synthesis e wehe i kahi liʻiliʻi o CO a me CO2 i loko;
6. Ma ke kiʻi: ka hoʻokumu ʻana ma ke ʻano he mea hoʻomohala;
7. Ma keʻano o ka'ōpala maoli: hoʻohanaʻia e like me ka coagulant;
8. I ka ʻoihana kūkulu: hoʻohana ʻia ʻo ia he anticoagulant.
