| Hazard Information | Back Directory | [Chemical Properties]
clear colourless liquid | [Uses]
Diisopropyl phosphite can be used as antiwear lubricant additive together with triphenyl thiophosphate on T8 steel/Al2O3 ceramics.
| [Preparation]
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)]
