Diisopropyl phosphite Chemical Properties,Usage,Production
Chemical Properties
clear colourless liquid, corrosive, soluble in organic solvents such as ethanol.
Uses
Diisopropyl phosphite is 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%.
