ʻEtilena glycol CAS 107-21-1

ʻO Ethylene glycol, i ʻike ʻia hoʻi ʻo glycol, ʻo ia ka diol aliphatic maʻalahi loa. Loaʻa iā ia nā waiwai kemika o nā waiʻona, e like me ka hiki ke hana i nā ethers a me nā esters, e oxidized e hana i nā aldehydes a i ʻole nā ​​​​acids, a e condense e hana i nā ethers. Hiki ke pani ʻia e nā halogens. Ke hana pū me ka acyl chlorides a i ʻole nā ​​​​​​anhydrides acid, hoʻokumu pinepine ʻia nā diesters. Ke hoʻomehana ʻia i ke alo o kahi catalyst (manganese dioxide, alumini oxide, zinc oxide a i ʻole sulfuric acid), hiki ke hoʻomaloʻo ʻia i loko o ka intramolecular a i ʻole intermolecularly e hana i ka cyclic ethylene glycol acetal, kahi e hana pū me ka nitric acid e hana i ka ethylene glycol dinitrate (kahi mea pahū). ʻO Ethylene glycol kahi mea maka no ka hana ʻana i nā resins polyester, alkyd resins, a me nā fibers polyester. Hoʻohana ʻia hoʻi ia ma ke ʻano he antifreeze kaʻa a me ka refrigerant mīkini mokulele.

ʻAno: Wai ʻole kala, moakāka, wai mānoanoa

Hoʻohana ʻia ʻo Ethylene glycol ma ke ʻano he mea maka no nā olonā polyester, a hoʻohana ʻia hoʻi i nā resins polyester ʻē aʻe, nā resins polyester unsaturated a me nā pena polyester 1730. Hiki ke loaʻa nā ʻano surfactants like ʻole mai ka ethylene glycol a me ka polyethylene glycol. ʻO kāna hui dinitro dinitroethylene glycol he mea pahū. Hiki i ka Ethylene glycol ke hoʻohaʻahaʻa i ke kiko hau o nā hopena wai, no laila hoʻohana pinepine ʻia ia ma ke ʻano he mea antifreeze.

ʻAno hana

1. Ke ʻano hydration pololei o ka Ethylene oxide

2. Ke ʻano hydration catalytic o ka Ethylene oxide sulfuric acid

3. Ke ʻano hana hydration pololei ʻo Ethylene

4. Ke ʻano hoʻoulu ʻana o ka Ethylene dichloride.

5. Ke ʻano hana Formaldehyde
