过氧化尿素是一种新型漂白、消毒剂,漂白、消毒效果优于H2O2和过氧乙酸,某工业用过氧化尿素的部分参数列于下表。

分子式外观热分解温度熔点水溶性(20℃)
CO(NH2)2·H2O2白色晶体45℃75—85℃500g·L—1
 

合成过氧化尿素的流程及反应器的示意图如下:

    

请回答下列问题:

(1)写出合成过氧化尿素的化学方程式:                                   

(2)反应器里冷凝管中冷水从   (填“上”或“下”)口流入;反应器的加热方式是   

①直接加热;②水浴加热;③蒸气浴加热;④冰浴

(3)搅拌器选用的材料是玻璃而不是铁质或铝质材料的原因是                

(4)从母液中分离出H2O2和尿素,采用的是减压蒸发、冷却结晶的方法,其原因是         

(5)活性氧含量的高低直接决定产品的质量,合格产品中活性氧的含量≥16%(相当于其中含H2O234%)。为了确定所得产品合格与否,质检员称取干燥样品2.000g,溶解于水,在250mL容量瓶中定容,准确量取其中25.00mL溶液于锥形瓶中,加入1mL 6mol/LH2SO4,然后用0.1000mol/L KMnO4标准溶液滴定样品中的H2O2(KMnO4溶液不与尿素反应),至滴入最后一滴时,溶液显浅红色且半分钟内不褪色,三次滴定平均消耗KMnO4溶液6.000mL:

完成并配平下列化学方程式:

    MnO4    H2O2    H+    Mn2+    H2O+    

②KMnO4溶液应盛放在          滴定管中,若滴定前滴定管尖嘴处有气泡,滴定后消失,会使测得的活性氧含量          (填“偏高”、“偏低”或“不变”);

③根据滴定结果确定产品质量       (填“合格”或“不合格”),活性氧的质量分数为
