Nā huahana
Isopropyl alcohol CAS No. 67-63-0
Hōʻike huahana
Hana ʻia ʻo DEG e ka hydrolysis hapa o ka ethylene oxide. Ma muli o nā kūlana, hana ʻia ka nui o DEG a me nā glycols pili. ʻO ka huahana i loaʻa he ʻelua mau molekole ethylene glycol i hui pū ʻia me kahi paʻa eter.
"Loaʻa ʻia ka Diethylene glycol ma ke ʻano he huahana hui pū me ka ethylene glycol (MEG) a me ka triethylene glycol. Ke hana maʻamau nei ka ʻoihana e hoʻonui i ka hana MEG. ʻO ka Ethylene glycol ka nui loa o nā huahana glycol i nā ʻano noi like ʻole. Loaʻa iā DEG e hilinaʻi ʻia ma luna o ka noi no nā derivatives o ka huahana mua, ethylene glycol, ma mua o nā koi mākeke DEG."

Hoʻohana ʻia ʻo Diethylene glycol i ka hana ʻana i nā resins polyester saturated a unsaturated, polyurethanes, a me plasticizers. Hoʻohana ʻia ʻo DEG ma ke ʻano he hale kūkulu i ka synthesis organik, e laʻa me morpholine a me 1,4-dioxane. He mea hoʻoheheʻe ia no ka nitrocellulose, resins, dyes, aila, a me nā mea hoʻohui ʻē aʻe. He humectant ia no ka paka, ka pahu, ka inika pai, a me ke kepau. He mea ia i loko o ka wai hoʻopalapala, lubricants, wallpaper strippers, hana noe a me ka haze solutions, a me ka hoʻomehana / kuke wahie. lotions, deodorants), hoʻololi pinepine ʻia ʻo DEG e nā eter diethylene glycol i koho ʻia. Hiki ke hoʻohana ʻia kahi hopena dilute o diethylene glycol ma ke ʻano he cryoprotectant; akā naʻe, hoʻohana pinepine ʻia ka ethylene glycol. Loaʻa ka hapa nui o ka ethylene glycol antifreeze i ka hapa nui o ka diethylene glycol, aia ma ke ʻano he hopena o ka hana ethylene glycol.
