Procedure
To 570 g (3.0 mol) of butyl ethylpropenylphosphinate (produced as in Example 6) are added 248 g (4 mol) of ethylene glycol and 0.4 g of potassium titanyl oxalate followed by stirring at 100° C. for 2 h. Volatiles are distilled off by gradual evacuation to leave 506 g (98% of theory) of 2-hydroxyethyl ethylpropenyl-phosphinate.
