将羟乙膦酸钠的合成方法由两步法改进为羟乙膦酸粗品不经重结晶直接成盐后加乙醇沉淀的“一锅合成法”，简化了生产工艺，提高了收率和产品质量。
The method of synthesizing etidronate is improved from two-step method to “one-pot synthesis method” of precipitating ethahydronaphthoic acid crude product without recrystallization and ethanol precipitation, which simplifies the production process and increases the yield and the product quality.
