Polyol phosphates nwere ike kewaa ụzọ abụọ: ụdị A bụ polyoxyethylene ether phosphate, nke bụ agba aja aja mado; Ụdị B bụ polyol phosphate nwere nitrogen, ngwakọta nke ogige polyhydroxy, nke bụ mmiri viscous ojii. Solubility nke organic phosphoric acid nkịtị na mmiri na-ebelata site na mmụba nke R alkyl carbon atom. Ma monoesters na diesters nke phosphate esters bụ acidic na nwere ike decompose hydrogen ion na aqueous ngwọta; na ọkara alkaline, a na-eme ngwa ngwa ire ere a.

N'ozuzu, glycerol na-agbaze site na phosphate wee jiri phosphonic acid mee ya. Mmeghachi omume oxidation nke glycerol bụ nke a: ịgwakọta glycerol na powdered caustic soda, kpo oku na 150 ℃ n'okpuru nchebe nke inert gas, wee na-agbakwunye ethylene oxide na ethylene oxide dị ka molar ratio nke ethylene oxide na glycerol nke 2: 1. na ịnọgide na-enwe okpomọkụ nke 150-160 ℃.
