Ma kahi o 3 miliona mau tona o ka adipic acid e hua ʻia i kēlā me kēia makahiki. Hoʻohana ʻia ma kahi o 10% i ka ʻoihana meaʻai ma Kanada, nā ʻāina EU, USA a me nā ʻāina CIS he nui.
Nā meaʻai e waiwai ana i ka waikawa adipic:
Nā ʻano laulā o ka adipic acid
ʻO ka waikawa Adipic, a i ʻole kapa ʻia ia, hexanedioic acid, kahi mea kōkua E 355 meaʻai e hoʻokani i ke ʻano o ka stabilizer (acidity regulator), acidifier a me ka pauka hoʻomoʻa.
ʻO ka Adipic acid i ke ʻano o nā aniani kala ʻole me ke ʻono kawa. Hana ʻia ia chemically e ka launa pū ʻana o cyclohexane me ka nitric acid a i ʻole nitrogen.
Ke mālama ʻia nei kahi noiʻi kikoʻī o nā waiwai āpau o ka adipic acid. ʻIke ʻia he haʻahaʻa-lāʻau kēia mea. Ma muli o kēia, hāʻawi ʻia ka ʻakika i ka papa palekana ʻekolu. Wahi a ka State Standard (i kākau ʻia ma Ianuali 12.01, 2005), he hopena maikaʻi iki kā ka adipic acid i nā kānaka.
ʻIke ʻia he hopena maikaʻi kā ka adipic acid i ka ʻono o ka huahana i pau. Hoʻopili ia i nā kino a me nā waiwai kemika o ka palaoa, hoʻomaikaʻi i ke ʻano o ka huahana i hoʻopau ʻia, kona hanana.
Hoʻohana ʻia i ka ʻoihana meaʻai:
- e hoʻomaikaʻi i ka ʻono a me nā ʻano kino a me nā kemika o nā huahana i hoʻopau ʻia;
- no ka mālama lōʻihi o nā huahana, e pale iā lākou mai ka palaho, he antioxidant.
Ma waho aʻe o ka ʻoihana meaʻai, hoʻohana ʻia ka waikawa adipic i ka ʻoihana māmā. Hoʻohana ʻia ia no ka hana ʻana i nā olonā i hana ʻia e ke kanaka, e like me polyurethane.
Hoʻohana pinepine nā mea hana iā ia i nā kemika hale. Loaʻa nā Esters o ka adipic acid i nā mea hoʻonaninani no ka mālama ʻili. Eia kekahi, hoʻohana ʻia ka adipic acid ma ke ʻano he ʻāpana no nā huahana i hoʻolālā ʻia e hoʻoneʻe i ka unahi a me ka waiho ʻana i nā lako hale.
ʻO ka pono o ke kanaka i kēlā me kēia lā no ka waikawa adipic:
ʻAʻole hana ʻia ka acidipika Adipic i loko o ke kino, a ʻaʻole ia he mea pono no kāna hana. ʻO ka palena kiʻekiʻe i ʻae ʻia i kēlā me kēia lā o ka waikawa he 5 mg no 1 kg o ke kaumaha o ke kino. ʻO ka palena kiʻekiʻe i ʻae ʻia o ka waikawa i ka wai a me nā mea inu ʻaʻole i ʻoi aku ma mua o 2 mg no 1 lita.
Hoʻonui ka pono no ka waikawa adipic:
ʻAʻole waiwai nui ka ʻakika adipic no ke kino. Hoʻohana wale ʻia e hoʻomaikaʻi i ka maikaʻi o ka meaʻai a me ke ola o nā huahana i hoʻopau ʻia.
E hoʻemi ka pono no ka waikawa adipic:
- i ka wā kamaliʻi;
- contraindicated i hāpai keiki a me ka lactation;
- i ka manawa adaptation ma hope o ka maʻi.
Assimilation o ka adipic acid
I kēia lā, ʻaʻole i aʻo piha ʻia ka hopena o kahi mea i ke kino. Manaʻo ʻia he hiki ke hoʻopau ʻia kēia waihona papaʻai i nā mea i kaupalena ʻia.
ʻAʻole komo piha ka waiʻakika e ke kino: haki kahi ʻāpana liʻiliʻi o kēia mea i loko. Hoʻopau ʻia ka adipic acid i ka mimi a me ka ea i hemo.
Nā waiwai kūpono o ka adipic acid a me ka hopena o ke kino:
ʻAʻole i loaʻa nā waiwai maikaʻi no ke kino kanaka. He hopena maikaʻi wale nō ka Adipic acid i ka mālama ʻana i nā huahana meaʻai, ko lākou ʻano ʻono.
Nā kumu e hoʻopili ana i ka ʻike o ka adipic acid i loko o ke kino
Komo ka Adipic acid i loko o ko mākou kino me ka meaʻai, a ke hoʻohana pū ʻia kekahi i nā kemika o ka hale. Hoʻopili pū ka māla o ka hana i ka ʻike acid. ʻO kahi kiʻekiʻe kiʻekiʻe o kahi mea i komo i ka hanu hanu hiki ke hoʻonāukiuki i nā membrane mucous.
Hiki i nā nui o ka waikawa adipic ke komo i ke kino i ka wā o ka hana ʻana i nā olonā polyurethane.
I mea e hōʻalo ai i nā hopena olakino maikaʻi ʻole ʻO ka waiwai i ʻae ʻia o ka mea i loko o ka lewa he 4 mg no 1 m3.
Nā hōʻailona o ka waikawa adipic keu
Hiki ke ʻike ʻia ke ʻano ʻakika i ke kino ma o ka hala ʻana i nā hoʻokolohua kūpono. Eia nō naʻe, hiki i kekahi o nā hōʻailona o ke keu o ka adipic acid ke kumu ʻole (e laʻa me ka maʻi ʻaʻai) o ka huhū o nā membrane mucous o nā maka a me ka ʻōnaehana hanu.
ʻAʻole i loaʻa nā hōʻailona o ka hemahema acid adipic.
Ka launa pū ʻana o ka adipic acid me nā mea ʻē aʻe:
Hana maʻalahi ʻo Adipic acid me nā mea ʻē aʻe. ʻO kahi laʻana, hiki ke hoʻoheheʻe nui ʻia ka mea a crystallize i ka wai, nā wai ʻona like ʻole.
Ma lalo o kekahi mau kūlana a me nā puke, hoʻopili ka mea me ka acetic acid, kahi hydrocarbon. ʻO ka hopena, loaʻa nā ether, kahi e loaʻa ai kā lākou noi ma nā lālā like ʻole o ke ola kanaka. ʻO kahi laʻana, hoʻohana ʻia kekahi o kēia mau mea pono e hoʻonui i ka ʻono kawa i nā meaʻai.
ʻAkika Adipic i ka cosmetology
Aia ka ʻakika Adipic i nā antioxidants. ʻO ka hana nui o kāna hoʻohana ʻana ʻo ka hōʻemi ʻana i ka acidity, e pale i nā huahana cosmetic i loaʻa iā ia mai ka deterioration a me ka oxidation. Hoʻokomo pinepine ʻia nā esters o ka adipic acid (diisopropyl adipate) i loko o nā ʻaila i hoʻolālā ʻia e hoʻomaʻamaʻa i ke ʻano o ka ʻili.
