4-苯基脲唑性质、用途与生产工艺
化学性质
无色柱状结晶。熔点209℃。易溶于乙醇，难溶于乙醚。遇氧化剂变深红色。
用途
稳定剂。该品是4-Phenyl-4H-1,2,4-tria-zoline-3,5-dione([4233-33-4])的前体，这是最活泼的亲二烯体。
用途
Diels-Alder 捕捉剂 4-苯基-1,2,4-三唑啉-3,5-二酮的前体。
用途
用作X光胶片稳定剂
生产方法
碳酸二乙酯与水合肼缩合得到肼基碳酸乙酯，然后与异氰酸苯酯加成，制得4-苯基-1-乙氧羰基氨基脲，使其与氢氧化钾溶液共热，得到的热溶液过滤后用浓盐酸使滤液酸化，冷却，滤出沉淀的4-苯基尿唑。原料消耗（kg/t）水合肼 700碳酸二乙酯 1300异氰酸苯酯 1100
