制备方法与用途

化学性质
这是一种无色透明的棱柱状晶体，易溶于水且其水溶液呈酸性；不溶于醚类、甲苯、四氯化碳和二恶烷中。

用途
它用作牛、羊、马反刍动物饲料添加物，还可作为阻燃剂、金属表面处理剂、清洗剂等。此外，它是优良的饲料添加剂，能够提供磷和非蛋白氮（尿素态氮）两种营养元素，特别适用于反刍动物饲用，能减缓牛、羊瘤胃和血液中氮的释放和传递速度，安全性比尿素高。它也是一种高浓度氮磷复合肥料，适用于碱性土壤，并对水稻、小麦、油菜等作物均有增产效果。除此之外，还可用作阻燃剂、金属表面处理剂、发酵营养剂、清洗剂和净化磷酸用助剂。

生产方法
二次结晶法：将含50%P2O5的湿法磷酸与60%（质量）的尿素溶液加入混合反应器中，在110℃条件下混合后，通过泵送入真空蒸发器中进行浓缩。随后离心分离并干燥，制得磷酸脲成品。为得到饲料级产品，可进行二次结晶。分离后的母液经浓缩后再返回混合反应器加以利用。化学方程式如下： [ \text{H}_3\text{PO}_4 + \text{CO(NH}_2\text{)}_2 \rightarrow (\text{H}_3\text{PO}_4)\cdot(\text{CO(NH}_2\text{)}_2) ]

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，然后将其加入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，随后将稀溶液预热，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、干燥后制得磷酸脲成品。同样地，化学方程式如下： [ \text{H}_3\text{PO}_4 + \text{CO(NH}_2\text{)}_2 \rightarrow (\text{H}_3\text{PO}_4)\cdot(\text{CO(NH}_2\text{)}_2) ]

  本发明公开了一种磷酸脲的制备方法，采用重量浓度大于75%的工业磷酸作为原料，加热到90～130℃后，控制速度喷入预先加入定量尿素颗粒或熔融尿素的带有搅拌功能的真空反应器中，在其中尿素和磷酸发生反应生成磷酸脲，反应过程中使反应器中形成真空环境，利用磷酸脲生成反应时放出的热量在真空条件蒸发掉磷酸带入的水分，从而得到干燥的颗粒状磷酸脲产品。采用该方法得到较高质量的磷酸脲产品。该方法完全避免了常规生产工艺中结晶母液处理或结晶液真空浓缩过程。该方法具有磷氮元素收率高、工艺流程短、操控简单方便、安全、易实现工业化等特点。
• Effect of Milk Thistle on the Pharmacokinetics of Indinavir in Healthy Volunteers
  作者：Stephen C. Piscitelli、Elizabeth Formentini、Aaron H. Burstein、Raul Alfaro、Shyla Jagannatha、Judith Falloon

  日期：2002.5

  Study Objective. To characterize the pharmacokinetics of indinavir in the presence and absence of milk thistle and to determine the offset of any effect of milk thistle on indinavir disposition. Design. Prospective open-label drug interaction study. Setting. Outpatient clinic. Subjects. Ten healthy volunteers. Intervention. Blood samples were collected over 8 hours after the volunteers took four doses of indinavir 800 mg every 8 hours on an empty stomach for baseline pharmacokinetics. This dosing and sampling were repeated after the subjects took milk thistle 175 mg (confirmed to contain silymarin 153 mg, the active ingredient) 3 times/day for 3 weeks. After an 11-day washout, indinavir dosing and blood sampling were repeated to evaluate the offset of any potential interaction. Measurements and Main Results. Indinavir concentrations were measured by using a validated high-performance liquid chromatography method. The following pharmacokinetic parameters were determined: highest concentration (Cmax), hour-0 concentration, hour-8 concentration (C8), time to reach Cmax, and area under the plasma concentration-time curve over the 8-hour dosing interval (AUC8). Milk thistle did not alter significantly the overall exposure of indinavir, as evidenced by a 9% reduction in the indinavir AUC8 after 3 weeks of dosing with milk thistle, although the least squares mean trough level (C8) was significantly decreased by 25%. Conclusion. Milk thistle in commonly administered dosages should not interfere with indinavir therapy in patients infected with the human immunodeficiency virus.

  研究目的描述茚地那韦在奶蓟草存在和不存在的情况下的药代动力学特征，并确定奶蓟草对茚地那韦处置的任何影响的抵消作用。 设计。前瞻性开放标签药物相互作用研究。 环境。门诊。 受试者。十名健康志愿者。 干预。志愿者每8小时空腹服用四次茚地那韦800毫克后，在8小时内采集血液样本，以测定基线药代动力学。受试者连续3周每天3次服用奶蓟草175毫克（经证实含有水飞蓟素153毫克，活性成分）后，重复上述剂量和采样。经过11天的冲洗后，再次进行茚地那韦剂量和血液采样，以评估任何潜在相互作用的抵消情况。 测量和主要结果。茚地那韦浓度的测定采用经过验证的高效液相色谱法。测定了以下药代动力学参数：最高浓度（Cmax）、0小时浓度、8小时浓度（C8）、达到Cmax的时间以及8小时给药间隔的血浆浓度-时间曲线下面积（AUC8）。服用奶蓟草3周后，茚地那韦的AUC8降低了9%，但最小二乘法平均谷浓度（C8）显著降低了25%，这表明奶蓟草并未显著改变茚地那韦的总体暴露量。 结论在人类免疫缺陷病毒感染者中，常用剂量的奶蓟草不会干扰茚地那韦治疗。

  公开号：US03936501A1

  公开（公告）日：1976-02-03

  The present invention relates to a process for the direct manufacture of crystalline urea phosphate. The process consists in the reaction of solid urea with ortho-phosphoric acid in a substantially anhydrous form. A concentrated phosphoric acid with above 90% by weight H.sub.3 PO.sub.4 can be used as starting reagent. A preheating of the phosphoric acid at 60.degree.-90.degree.C is preferred in order to induce the spontaneous reaction with the solid urea. The urea phosphate product obtained is ready for use without any further operation. Desired micronutrients such as Mg, Co, Fe, Zn, Cu, Mn may be incorporated in the initial ortho-phosphoric acid prior to the reaction with the solid urea.

  本发明涉及一种直接制造结晶尿素磷酸盐的方法。该方法包括将固体尿素与基本无水的正磷酸反应。可以使用含有90％以上H.sub.3 PO.sub.4的浓磷酸作为起始试剂。为了诱发与固体尿素的自发反应，首选将磷酸预热至60℃-90℃。所得的尿素磷酸盐产品无需进一步操作即可使用。在与固体尿素反应之前，可以将所需的微量营养素如Mg、Co、Fe、Zn、Cu、Mn并入初始的正磷酸中。
