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 i te warowaiha me te ethylene bromide.
3. Kei roto i te hau rewharewha.
