Etilene glycol CAS 107-21-1

O le Ethylene glycol, e ta'ua fo'i o le glycol, o le aliphatic diol sili ona faigofie. E iai ona uiga fa'akemikolo e pei o le ava malosi, e pei o le gafatia e gaosia ai ethers ma esters, e fa'a'okesaita e gaosia ai aldehydes po'o acids, ma e fa'aputu e gaosia ai ethers. E mafai fo'i ona sui i halogens. Pe a tali atu i le acyl chlorides po'o acid anhydrides, e masani ona fausia ai diesters. Pe a fa'avevela i le i ai o se catalyst (manganese dioxide, aluminum oxide, zinc oxide po'o le sulfuric acid), e mafai ona fa'amago i totonu po'o le va o molekula e gaosia ai le cyclic ethylene glycol acetal, lea e tali atu i le nitric acid e gaosia ai le ethylene glycol dinitrate (o se mea pāpā). O le Ethylene glycol o se mea mata mo le gaosiga o polyester resins, alkyd resins, ma polyester fibers. E fa'aaogaina fo'i o se mea e tete'e ai i le aisa mo ta'avale ma le refrigerant mo afi va'alele.

Foliga Vaaia: Vai e leai se lanu, manino, ma mafiafia

Fa'aaogāga E fa'aaogā tele le ethylene glycol o se mea mata mo alava polyester, ma e fa'aaogā fo'i i isi resins polyester, unsaturated polyester resins ma vali polyester 1730. E mafai ona maua mai le ethylene glycol ma le polyethylene glycol ituaiga eseese o surfactants. O lona dinitro compound dinitroethylene glycol o se mea pāpā. E mafai e le ethylene glycol ona fa'aitiitia le tulaga aisa o vaifofo vai, o lea e masani ona fa'aaogā o se vaila'au e tete'e ai i le aisa.
