| Questions And Answer | Back Directory | [Preparation]
The esterification method using phosphorus oxychloride as raw material involves reacting a fatty alcohol of two or more groups with phosphorus oxychloride at a temperature below 20°C for at least 24 hours, and then obtaining trialkyl phosphate by vacuum distillation. Among them, the product obtained by reacting phosphorus oxychloride and isoamyl alcohol at a temperature of around 10°C for 45 hours is 1-BUTANOL,3-METHYL-,PHOSPHATE. | [Uses]
Triisoamyl phosphate (TiAP) is considered an excellent extractant for the extraction and separation of actinide elements due to its superior physicochemical properties, and is particularly suitable for systems with high irradiation doses and systems with high relative plutonium concentrations. |
