水溶性聚磷酸铵（APP）因其高养分、高水溶性、缓释效果好、易复配等诸多优点，被广泛用作高浓度水溶肥和液体肥的基础原料。但目前市面上，高水溶性APP工业制备困难，且产品不多。通过对APP合成条件进行简单优化，来提高APP的溶解度，制备高水溶解产品。研究反应原料的物料比、反应温度和反应时间等对水溶性APP产品溶解度及其他指标参数的影响。结果显示，合成较优条件为原料尿素和磷酸一铵（MAP）物质的量之比为0.48，反应温度为200℃，反应时间为1.5～2.0 h。该方法生产的APP产品在100 g水中溶解度≥170 g，且其他指标均较优，远高于行业标准（HG/T 5939—2021）要求。该工艺提高了水溶性APP产品的溶解度，提升其产品市场竞争力，有助于高浓度水溶性肥相关产品的发展。
Abstract：Water-soluble ammonium polyphosphate(APP) is widely used as the basic raw material of concentrated water-soluble fertilizer and liquid fertilizer because of its high nutrients,high water-solubility,good slow-release effect,easy compounding and many other advantages. Nevertheless,the industrial preparation of high water-soluble APP remains a significant challenge,with a limited number of products currently available on the market. It is hoped to improve the water solubility of APP by simply optimizing the APP synthesis conditions to prepare highly water-soluble products. The impact of the ratio of reactants,temperature and time on the solubility and other index parameters of water-soluble APP products is studied. The results demonstrated that the optimal conditions for the synthesis are a 0.48 molar ratio of raw material urea to MAP,a reaction temperature of 200 ℃,and a reaction time of 1.5-2.0 h. The water solubility of APP products produced by this method is found to be ≥170 g in 100 g water,with all other indexes exhibiting superior performance and exceeding the requirements set forth by the industry standard(HG/T 5939—2021). The process enhances the water solubility of water-soluble APP products,thereby augmenting their market competitiveness and facilitating the advancement of products pertaining to high-concentration water-soluble fertilizers.
