制备

二次结晶法 将含50%P2O5的湿法磷酸和60%(质量)的尿素溶液加入混合反应器中，在110℃混合后用泵送入真空蒸发器中进行浓缩，再离心分离、干燥，制得磷酸脲成品。为得到饲料级产品，可进行二次结晶。分离后母液经浓缩，再返回混合反应器加以利用。 真空浓缩一步法 将含25%P2O5的稀磷酸(含6%杂质)用烧碱预处理并倾析以除去氟硅酸钠，然后将其加到有熔融尿素的间歇反应槽内，配料比为21g尿素对100g磷酸溶液。在此条件下，磷酸脲完全溶解，然后将稀溶液预热，再进入真空浓缩器(P＜13.3×100 Pa)于60℃进行浓缩。然后送到结晶器中冷却至20℃析出结晶。料浆在母液澄清槽中倾析，产品经少量水洗涤、干燥，制得磷酸脲成品。
