Procedure

To 416 g (2 mol) of butyl ethyl(3-hydroxypropyl)phosphinate (produced as in Example 11) are added 155 g (2.5 mol) of ethylene glycol and 0.4 g of potassium titanyloxalate, followed by stirring at 200° C. for 2 h. Volatiles are distilled off by gradual evacuation to leave 439 g (98% of theory) of 2-hydroxyethyl ethyl(3-hydroxypropyl)phosphinate.
