実験手順

Tris-(2-chloroethyl) phosphite is prepared from phosphorus trichloride and ethylene oxide, and bis(2-chloroethyl) 2-chloroethanephosphonate, inter alia, is formed therefrom by Arbusov rearrangement. After phosgenation and splitting off of hydrogen chloride by means of heat, vinylphosphonic acid dichloride results, which, after purification by distillation, is hydrolyzed with water to give pure vinylphosphonic acid.
