1.     Background

Oxalamide, also known as oxalic acid diamide, CAS login number: 471-46-5. Its molecular weight is 88.07, nitrogen content is 31.8%, slightly soluble in water, insoluble in ethanol and ethyl ether, does not absorb moisture, stable nature, easy to store, can be decomposed into ammonia and carbonic acid, is a good and efficient slow-release fertilizer. Oxamide compared with traditional fast effective nitrogen fertilizers (such as urea) in China: it‘s not volatile, insoluble in water, not easy to lose, the nitrogen utilization rate is high, and it can reduce economic losses and water pollution. 

Oxalamide, as an efficient slow-release fertilizer, will have a huge market and broad prospects in China.
