Purification Methods |
This fireproofing agent, and ingredient for making polymers, is obtained as a syrup on hydrolyzing vinylphosphonyl dichloride with cold H2O and solidifies on prolonged drying over P2O5/KOH. When distilled at 235-240o/0.0006mm, it gives the anhydride (d 1.304, n 1.5874) [Kabachnik & Medvedi Izvest Akad Nauk SSSR, Ser Khim 868 1953, Chem Abstr 54 10834 1960]. It is best kept as the sodium salt (m 350o) which precipitates when a solution of EtOH containing NaOEt (from 2g of Na) is added to vinylphosphonic acid (3.2g), and is recrystallised from EtOH (5.1g, quantitative). The p-anisidinium salt forms mauve prisms m 250o (from EtOH/Et2O). The dimethyl ester, M 136.1, d4 1.1405, nD 1.4330, has b 72.5o/10mm and 197-202o/760mm. [Kabachnik et al.

General Description |
Vinylphosphonic acid (VPA) is an organophosphorus compound that is used in the surface treatment of metal substrates. It can be used in the preparation of poly(VPA) by radical polymerization in the presence of initiator systems and chain transfer agents. PVPA tends to have an electrolytic nature, which is useful for a variety of energy based applications. |
