ʻO Ethylene glycol, i ʻike ʻia hoʻi ʻo glycol, ʻo ia ka diol aliphatic maʻalahi loa. Loaʻa iā ia nā ʻano kemika o nā waiʻona, e like me ka hiki ke hana i nā ethers a me nā esters, hiki ke oxidized e hana i nā aldehydes a i ʻole nā ​​​​akika, a hiki ke hoʻopili e hana i nā ethers.

ʻAno: wai ʻole kala, moakāka, wai mānoanoa.

Nā Hoʻohana: Hoʻohana nui ʻia ka 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 a no laila hoʻohana pinepine ʻia e like me ka antifreeze.
