1. Aloese mai le fa'afeso'ota'i ma oxidants, acids ma alkalis. O se vai e mu, fa'amolemole fa'alogo lelei i le puna o le afi. E le pala i le kopa, u'amea malu, u'amea u'amea po'o alumini.
2. Mea tau vailaʻau: faʻamautu, alkali e mafai ona faʻavaveina lona hydrolysis, acid e leai sona aafiaga ile hydrolysis. I le i ai o u'amea u'amea, silica gel, ma activated carbon, e pala i le 200°C e maua ai le carbon dioxide ma le ethylene oxide. Pe a tali atu i le phenol, carboxylic acid ma amine, β-hydroxyethyl eter, β-hydroxyethyl ester ma β-hydroxyethyl urethane e gaosia i le faasologa. Fa'apuna i le alkali e maua ai le carbonate. O le Ethylene glycol carbonate e faʻavevela ile vevela maualuga ma le alkali e fai ma faʻamalosi e gaosia ai le polyethylene oxide. I lalo o le gaioiga o le sodium methoxide, ua gaosia ai le sodium monomethyl carbonate. Fa'amuta le ethylene glycol carbonate i le hydrobromic acid concentrated, fa'amafanafana i le 100°C mo ni nai itula i totonu o se fa'amau fa'amau, ma fa'apala i le carbon dioxide ma le ethylene bromide.
3. O lo'o iai ile kasa fa'a'a'a'a.
