실험 절차
A three-neck round-bottom flask with fitted KPG stirrer, reflux condenser and dropping funnel is initially charged with 44.0 g of paraformaldehyde (95%), 105.5 g of demineralized water and 233.4 g of diethylamine hydrochloride, followed by the addition of 100.1 g of ethylphosphonous acid (96.3%) (prepared according to example 1) during 6 h at 110° C. with stirring. The pH of the reaction solution is adjusted to below 1 with 8 g of 37% hydrochloric acid. After one hour of refluxing, a solution of ethyldiethylaminomethylphosphinic acid is obtained.
