1. A ape i te pa atu ki nga waikura, waikawa me te kawakore.He wai muramura, no reira kia tupato ki te puna ahi.Ehara i te kino ki te parahi, te rino ngawari, te kowiri tira, te konumohe ranei.
2. Ngā āhuatanga matū: he āhua pūmau, ka taea e te alkali te whakatere i te hauwai, karekau he painga o te waikawa ki te hauwai.I te aroaro o te waikura whakarewa, te silica gel, me te waro whakahoaho, ka pirau i te 200°C hei whakaputa i te waro hauhaa me te ethylene oxide.Ina tauhohe ana ki te phenol, te waikawa carboxylic me te amine, ka puta te β-hydroxyethyl ether, β-hydroxyethyl ester me te β-hydroxyethyl urethane.Kohuatia ki te kawakawa kia puta te warowaiha.Ko te Ethylene glycol carbonate ka whakamahana i te pāmahana teitei me te kawakore hei whakakorikori hei whakaputa i te waikura polyethylene.I raro i te mahi a te konutai methoxide, ka puta te konutai monomethyl carbonate.Whakarewahia te ethylene glycol carbonate ki roto i te waikawa hydrobromic concentrated, whakamahana i te 100°C mo etahi haora i roto i te ngongo hiri, ka pirau ki roto ki te warowaiha me te ethylene bromide.
3. Kei roto i te hau rewharewha.
