Abstract: When calcium hydroxide is used as a phosphorus-fixing agent in the pyrolysis treatment process of waste tributyl phosphate (TBP) solvent,it shows poor compatibility to TBP,and is easy to settle and stratify.Therefore,the modified calcium hydroxide with good dispersibility in waste TBP is successfully prepared from calcium oxide and bisphenol A,and its structure is characterized by XRD,SEM and FT-IR.The dispersion properties of modified calcium hydroxide,which is prepared under different conditions,in TBP solvent are compared.The modified calcium hydroxide,which is prepared under the optimum conditions that the mass of bisphenol A is 1.5 g,the reaction temperature is at 75℃,and reaction lasts for 1.5 h,has the best modification effect.The feed liquid prepared between modified calcium hydroxide and waste TBP can remain stable for 80 h.
