실험 절차
A 1 l five-neck flask equipped with thermometer, reflux condenser, high-performance stirrer and dropping funnel was initially charged with 447 g (3 mol) of butyl ethylphosphonite (produced as in Example 2) and 159 g (3 mol) of acrylonitrile. While stirring, 15 ml of sodium butoxide (30% strength in butanol) are added dropwise at such a rate that a reaction temperature of max. 120° C. becomes established. The crude product thus obtained is distilled in vacuo to obtain 548 g (90% of theory) of butyl ethyl(2-cyanoethyl)phosphinate as colorless liquid.
