| | 亜りん酸ジイソプロピル Usage And Synthesis |
| 外観 | 無色～わずかにうすい黄色, 澄明の液体 | | 化学的特性 | clear colourless liquid, corrosive, soluble in organic solvents such as ethanol. | | 使用 | Diisopropyl phosphite is used as antiwear lubricant additive together with triphenyl thiophosphate on T8 steel/Al2O3 ceramics. | | 製造方法 | Diisopropyl phosphite is prepared by directly reacting isopropanol with phosphorus trichloride.
3(CH3)2CHOH+PCl3→[(CH3)2CHO]2POH+2HCl↑+(CH3)2CHCl
At a ratio of 3:1 (mol), continuously feed 215kg/h of isopropanol and 150kg/h of phosphorus trichloride. When mixed, this results in a violent reaction that generates hydrogen chloride gas. This gas is quickly removed from the mixing pot using vacuum mercury. The crude ester produced is then heated in a falling film type spinner deacidification device and further deacidified. The resulting product is then cooled to below 40°C and obtained with a content of 92%-95% and a yield of 95%～98%. | | Synthesis Reference(s) | Tetrahedron Letters, 29, p. 3327, 1988 DOI: 10.1016/0040-4039(88)85153-0 |
