Water → 3-[Ethyl(hydroxy)phosphoryl]propanoic acid

Participants

Reaction Steps

444 g (2 mol) of 3-(ethylbutoxyphosphinyl)propionic acid (produced as in Example 13) are initially charged in a 1 l five-neck flask equipped with thermometer, reflux condenser, high-performance stirrer and dropping funnel. At 160° C., during 4 h, 500 ml of water are metered in and a butanol-water mixture is distilled off. The solid residue is recrystallized from acetone to obtain 309 g (93% of theory) of 3-(ethylhydroxyphosphinyl)propionic acid as colorless solid.
