Propylene glycol - He aha ka mea? Nine waiwai, ka hoʻohana 'ana o

Kekahi o ka loa, he pono ole i loko o ka mea hoʻonani, ala a me ka ai na hana, e like me ka oaoieei-poepoe mea he aloha waiwai no i ka waiʻona mai ke kino. Kona inoa - propylene glycol. He aha ka mea? E hoomanao i ka waiwai, hakakino 'ole a me ka hana ana o keia hui i loko o ka pauku.

Propylene glycol - He aha ka mea?

hoomaka kēia dialcohol kanaka e hoʻohana i ka wa a ka mea i loaʻa mai i ka mea pono keia mau mea, a nui ka waiwai ka mea, inā paʻa. Externally ka mea, i kekahi uuku mai ethanol paha glycerol, e like me ka maopopo wai. Eia naʻe, kona (viscosity) Ua oi aku ma mua o ethanol, akā, haʻahaʻa ma mua ia o ka glycerol. E like me ka kaʻawahia ia mea emi iki mahope o nui i ka hapa hoalauna ma ka homologous moʻo -'etolina glycol.

Inā ethanediol - ka ikaika ka mea awaawa make, ai ka propylene glycol - ole. I ka hana ana i keia mea ua ka nānā 'ana ma luna o kona kino a me ka Nine Inch waiwai. Inā mākou pokole hōʻike i nā nāʻoihana ka papa kuhikuhi ma a he mea propylene glycol, ke noi e e hoike i loko o kekahi mau nāʻoihana o ka hoʻokele waiwai.

1. Nine hana.
2. Mokulele a me ka ulia kaʻa? Ieoaeunoai.
3. Oil a me ke kinoea oihana puolo.
4. Pena a me varnish oihana puolo.
5. Mea hoʻonani a me ka perfumery oihana puolo.
6. Food? Iecaianoaaiiuo.
7. Kōmike ke kahua o ka ha awina.
8. Medicine.

Ka mea, ua maopopo i ka mea, e manao ana mākou i ka waiwai o ka waiwai Nine Inch maka mea a me ka mea nui i pale no ka mea maʻamau? Iecaianoaaiiuo a me ka hana ana o kekahi mau hale. Ia mea ke kumu o ka? Iecaianoaaiiie o ka huina hoonui e ke pōpilikia i tons no ka makahiki. lawe i kona waiwai hoʻolilo a me nā waiwai hoʻokomo ma waena o nā aupuniʻelua mai 'Imi. Kokoke i na kahua o ka ha awina, a? Iecaianoaaiiuo e loli ai i ka hoʻohana 'ana o ka waiwai e like me propylene glycol. He aha ka mea? He aha ka kona Nine Inch 'ole, haʻilula a me ka waiwai? Mākou e noiʻi ana no hoi ia.

Ke haʻilula a me ka lātoma

Aia i kekahi mau Lolina o na nā papakuhikuhi ma i oe ke hoike mai i wale i ka qualitative a laupaʻi haku mele 'ana o ka lātoma, akā, i ka mea o'ātoma paa ana i loko o laila,ʻo ia hoʻi, ka' ole o ka mea.

1. Hakakino ole empirical. E like me keia haʻilula hiki e hookolokoloiaʻi e au, ma o ka haku mele 'ana o ka hui. Propylene glycol e hōʻike me C ₃ H ₈ O _2. Akā, ua ka mooolelo 'aʻole e haawi aku i ka manawa kūpono e wńnana i ka waiwai o ka waiwai, no ka mea, o ka mea o'ātoma IKE OLE IA.
2. Ke Punk mall haʻilula. Ma keia hihia, ke propylene haku mele 'ana i ka ua haʻilula akā, e loaʻa mauʻano: 1,2 - propanediol Ch ₂ OH-CHOH-Ch _3, a me 1,3-propanediol Ch ₂ OH-Ch ₂ -CH ₂ OH. Ke kulana o ka iaea ooieoeiiaeuiiai pūʻulu ololi ka reactivity o ka waiwai. Ma waena o lakou iho i ka hale a mau - isomers.
   
3. Full mall haʻilula. Ua hōʻike kēlā mea paʻa i loko o ka lātoma, a me kekahi hui ma waena o kalapona a me ka hydrogen. i ke propylene glycol a pau nā loulou hookahi sigma-type, no laila, o ia ho i ka piha ano o ka 'ole hana.

E like me ka mea waiwai propylene - he wai i mea he racemic läÿau, he mau'ōnohi isomeric hale. O ke kumu ho i ka asymmetric kalapona'Ātoma i loko o ke kaulahao. Nolaila, kekahi ke ka ao ka pelane o polarized malamalama ma ka akau, a me ka ae waiho no kekahi. Naʻe, i ka waiwai o ka mea waiwai, e like me ka poe mea kokoke i kanawai.

Helu waiwai o ka waiwai

Ma hua'ōlelo o physical kiko'î, 100% propylene glycol i ke kēia mau 'ano.

1. Colorless wai, manoanoa, (viscosity), i he kaulana nuʻa waiwai.
2. Ma ke kīleo, sweetish, ala i ho'ākāka '.
3. He He maikai'ūheheʻe no na lunamakaainana oʻaneʻane nā papa o ka waiwai.
4. Sam propylene glycol Ua wailana i ka wai a me ka waiʻona a me ka hewa - ma ka benzene a me Etera.
5. Ka baila aʻela i wahi o - 45.5 ⁰ C ma maʻamau puʻe. uku, piʻi pū me ka māhuahua puʻe.
6. Ua loaʻa He kiʻekiʻe loa o ke hygroscopicity.
7. Ua hōʻike haʻahaʻa ka popopo ioeaie.

Oia physical waiwai, a hooholo i ka papa kuhikuhiE kihapai o ka noi o ka waiwai. Ma hope o propanediol hiki ke mitigate i ka puaʻa hiwa paʻa meakino pahele lewa ona mau, a nakinaki ia ia, ua hakumakuma i ka mahana o ka waiwai, hoʻonoho liʻiliʻi ia i ka puni hui. No laila, ka mea, ua hoʻohana 'ia i loko o ka meaʻai oihana puolo.

Nine Inch mall

Mai ka viewpoint o reactivity, 1,3-propylene glycol Ua oi kū'ē isomer. Eia hou, oia mea hiki ke polymerize. I mau, he mea e hiki ke komo i ka dihydric ka waiʻona kekahi mau nui reactions.

1. Esterification. Me ke aloha a me ka'okanikaʻole nāʻakika ua reacted e lilo nā mea kemika.
2. By naoh me ka mekala 'åkilikai haawi glycolates, o ka mea hana ma ka AaOIeIOUIeXAOAaIN me ka mekala' åkilikai ke hooheheeia.
3. Hiki o dehydration me ke kahua o ka aldehydes, allylic waiʻona mai ke kino dimetildioksanov a me nā huahana.
4. Dehydrogenation reactions alakai i ke kahua o ka acetol, aldehydes, nāʻakika.
5. Ke'okesaside ua pu ma ke kahua o nā lātoma o acetone, propionaldehyde, lacticʻakika, formaldehyde a me nā hui.

I ka hana ana o keia waiwai ma ka hana ua noʻonoʻo palekana no ke kaiapuni. Ua, like me ka hopena o iiyoaiiay palaho lātoma hana pono i ka wai a me ka o carbon dioxide. Ke kaʻina Ua like penei:

• propylene glycol;
• lacticʻakika;
• PVK (pyruvicʻakika) ;
• ka wai;
• o carbon dioxide.

Ua nolaila, ua manaoia e hiki ke hoʻohana i kēia pili no kekahi mau hana: ia kūkaʻi 'a me ka ai a me ka mea hoʻonani.

Kaʻawahia 'ole ma ke kino, a

Propylene glycol - He aha ka mea i loko o hua'ōlelo o ka hopena ma luna o ke kanaka kino? Lehulehu haʻawina a me ka ike maopopo ana i hoike mai, i ka pololei hopena maikaʻi ma luna o nā'aʻaʻa ola a me nā loko, i kēia hui, aole ia i ole ʻAʻole anei i i mea ukiuki loa a me ka redness o kaʻili, aole i loaa i loko o ke ake, a konāhua, like, mai hemo mai a hiki ma ke ala iā ia.

Ho okolohua maʻiole i ka lukuʻia i kela la i keia propylene glycol, hoao iho la ia ia, aole ia e pili i ke ola kino a me ke ola o ka poe ola mea. Eia naʻe, inā he lōʻihi manawa e hoʻohana i nā huahana, a hoʻomākaukau i loaʻa ka nui dala o ka waiwai, ke hoomanawanui hakuʻala, kā lākou hana a me ka manao pono, e ke compromised. Akā, i kēia lā i ka nui nui oʻano nui maemae 100% propylene glycol, i mea o ka papa ole i ke Akua.

No laila, ke hoʻohana 'o ka waiʻona i loko o ka mea hoʻonani, ala a me ka meaʻai hana ua' ae e like me na rula a me na hooponopono ana. Na wale hopena maikaʻi ka mea, ke i ma luna o ka poʻe i hana eha iaʻi mai ka ili mai, dermatitis, eczema a me ka luna 'ano o ka allergy. Ma keia hihia, ka mea, ua i paipai i ka hoʻohana holika, me ka hinu, shampoos a me nā huahana i pihaʻi me ka waiwai.

Manufacturing hana

Nine waiwai ae propylene e loaa propylene'okesaside mai ia ma lalo o kekahi mau kumu o ka mahana (200 ⁰ C) a me ka puʻe (1.6 MPa). Ma keia hihia i nā huahana e pono ekolu nā mea hoʻohui:

• propylene glycol;
• glycol;
• tripropylene.

No ka hou aaioee a me ka hoʻolaʻaʻia papa hana i ka mea kūikawā rectifying kolamu ua hoʻohana 'ia. Ka hoʻopauʻana o ke huahana i ke kiʻekiʻe maemae waiwai (99%), a no ia mea, hoouna koke ae makaukau no ka hoʻohana. Food propylene glycol undergoes nā aaioee, pūnaewele au o ka mai i mau makahiki.

E hoʻohana i like antifreeze

Mua o nā mea a pau i ka waiʻona ua hoʻohana 'ia ma ka hana like o ka wela lawe. Propylene glycol hiki ke hoʻohana 'ia i loko o teploustanovkah i loko o ke ana wela huahelu mai -40 ⁰ C i 108 ⁰ C. A, kona haʻahaʻa ka popopo hiki e leie aku e malama i ka lako a pan. No ia mea, propanediol ua hoʻohana 'ia no:

• paio hahana maoli nō;
• hoʻoikaika kino o nā ano o ka hale;
• hoʻokomo ea;
• Anuanuʻai.

Hoʻohana 'ia i loko o nā mea hoʻonani

I ka hiki ana o ka waiwai, e hopu, a hoopaa i ka wai, hoopuehuia, ka hoʻomaikaʻi hionapāʻili, ala nā lātoma lawe underlies mea hana i nā mea hoʻonani, a perfumery na hana. Eia hou, i ka haʻahaʻa reactivity a me ka maluhia ma ka hua'ōlelo o ke kālaikaiaola, lapaʻau i hooholo i ke koho ana o keia ke keʻena mea e ho okumu holika, shampoos, kāpili ma luna, me ka hinu a me nā huahana.

He nui nā poʻe e kaumaha aku i ka kūʻai propylene glycol. Price hilinaʻi nui ma luna o ka lehulehu o ka huina hoonui a me ka nui o ka mea. Ua papa koa, mai 150 a hiki i 170 rubles no kilogram.

Ke hana i loko o ka meaʻai hana

Ma ka meaʻai hana propylene glycol i kapa like E1520. He He He l & acirclâ 'o ka nui huahana mea i pasty, creamy hana mau a me ka paa confectionery. Kona kūlana - lakou hoopuehu, hoopalupaluia, ka huʻihuʻiʻana, science.
