Ka kakaretso, glycerol e na le oxidized ke phosphate ebe e tšeloa ka phosphonic acid. Karabelo ea oxidation ea glycerol ke e latelang: ho kopanya glycerol le phofo ea caustic soda, ho futhumatsa ho 150 ℃ tlas'a tšireletso ea khase e sa sebetseng, ebe o eketsa ethylene oxide ho ethylene oxide ho latela molar ratio ea ethylene oxide ho glycerol ea 2: 1, le ho boloka mocheso oa 150-160 ℃. Ha ethylene oxide e eketsoa mme e bolokoa ka nako e itseng (e kang 1.2 h), ethylation ea oksijene ea glycerol e ka nkoa e phethoa. Ts'ebetsong ena, ho eketsoa ha caustic soda account bakeng sa hoo e ka bang 0.1% ea kakaretso ea glycerol le ethylene oxide.
