ʻO nā mea hoʻoheheʻe ʻia ʻo Diethylene Glycol Huahana CAS No 111-46-6 ʻO ka wai alohilohi.

ʻO ka wehewehe pōkole:

ʻO ka Diethylene glycol (DEG) he hui lāʻau me ke ʻano (HOCH2CH2)2O. He wai waihoʻoluʻu ʻole, ʻano ʻala ʻole, a hygroscopic wai me ka ʻono ʻono. He ʻehā kalapona dimer o ka ethylene glycol. Hiki ke komo i loko o ka wai, ka waiʻona, ka etera, ka acetone, a me ka ethylene glycol. ʻO DEG kahi mea hoʻoheheʻe i hoʻohana nui ʻia. Hiki ke lilo i mea haumia i nā huahana consumer; ua hopena kēia i nā maʻi maʻi ʻawaʻawa mai ka hoʻomaka ʻana o ke kenekulia 20.

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."

Palapala noi

Hoʻohana ʻia e like me ke kinoea dehydrating agent a me ka mea hoʻoheheʻe aromatics, hoʻohana ʻia e like me ka lubricant textile, softener a me ka mea hoʻopau hoʻopau, a me ka plasticizer, humidifier, sizing agent, nitrocellulose, resin and grease solvent.

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.

Pōmaikaʻi

ʻO ka maikaʻi o ka huahana, ka nui kūpono, ka hāʻawi maikaʻi ʻana, ke kūlana kiʻekiʻe o ka lawelawe He ʻoi aku ka maikaʻi ma mua o kahi amine like, ethanolamine, i hiki ke hoʻohana ʻia kahi kiʻekiʻe kiʻekiʻe no ka hiki ʻana o ka corrosion. ʻAe kēia i nā mea hoʻomaʻemaʻe e holoi i ka hydrogen sulfide ma kahi haʻahaʻa haʻahaʻa o ka amine me ka liʻiliʻi o ka hoʻohana ʻana i ka ikehu.
