108-19-0缩二脲,AR,98%化合物描述
Biuret is a chemical compound with the chemical formula C2H5N3O2. It is also known as carbamylurea. It is the result of condensation of two molecules of urea and is an impurity in urea-based fertilizers. This white solid is soluble in hot water. Biuret was first prepared and studied by Gustav Heinrich Wiedemann (1826 - 1899) for his doctoral dissertation, which was submitted in 1847. His findings were reported in several articles.
The term "biuret" also describes a family of organic compounds with the functional group -(HN-CO-)2N-. Thus dimethyl biuret is CH3HN-CO-NR'-CO-NHCH3. A variety of organic derivatives are possible.

生产方法及用途
生产方法
1.将尿素、水、磷酸氢二钠混匀,加热溶解。升温至150-160℃,保温2h。反应毕,将反应物倾入水中,放置过夜,滤出结晶为粗品,经稀氨水重结晶,得成品缩二脲。在尿素生产中,以中间尿液为原料,经高温热缩、分离、干燥即为成品。
2.工业上用尿素联产法,以中间尿液为原料,经高温热缩、分离、干燥得成品。实验室里可将尿素、磷酸氢二钠溶于水,于150~160℃下反应2h,然后倾入冷水中过夜,分离出结晶,即为缩二脲。
用途
用作医药中间体、生长激素、发泡剂、制漆作为非蛋白氮源加于饲料,通过动物瘤胃中的微生物合成本蛋白,以满足动物对蛋白质的需要,比尿素安全。是优良的动物饲料添加剂。
