反応手順

0.780 g of aluminum hydroxide, 1.47 g of methylphosphonic acid, and 6.64 g of water were mixed and stirred for 1 hour. Then the mixture was placed in an internal cylinder of Teflon in a stainless steel pressure-resistant vessel, which was placed in turn in a constant-temperature bath, and the mixture in the vessel was heated under autogenous pressure at 160° C. for 48 hours. After cooling to room temperature, suspended needle crystals were scooped out, washed with water, and dried in air, to obtain 0.97 g of aluminum methylphosphonate. The product gave essentially the same powder X-ray diffraction pattern as that in Example 4, and the product also contained a phase that gave essentially the same powder X-ray diffraction pattern as that in Example 1.
