Procedure

To a 250 ml three neck flask fitted with a reflux condenser and dropping funnel is added deionized water, 70% phosphorous acid (0.038 mole), 37% aqueous formaldehyde (0.075 mole), HCl (2.5 grams), and H2SO4 (2.5 grams). This is stirred vigorously and heated to reflux. Then, 5.6 grams (0.025 moles) of N-2-aminoethyl-3-aminopropyltrimethoxysilane is added dropwise. The mixture is heated and stirred overnight. After the reaction cooled, a sample is neutralized with 50% sodium hydroxide.
