Abstract
Description
technical field
[0001] This invention relates to the synthesis method of percarbamide and the screening of novel stabilizer. The synthesis method has simple route, simple operation, high yield, no pollution, and the waste liquid can be recycled. Background technique
[0002] Percarbamide is a new fine chemical product. It is a crystal adduct of hydrogen peroxide and urea. It is a white crystalline powder with a theoretical active oxygen content of 17.02%. It is easily soluble in water. The aqueous solution contains both hydrogen peroxide and The properties of urea aqueous solution, good stability, slow release of oxygen, long effective time, has a wide range of uses (such as bleaching, sterilization, disinfection, etc.), and has a wide range of application prospects. However, this important fine chemical product is still in a blank in the industry and needs to be developed and applied urgently. At present, the production capacity of sodium percarbonate complete set has rea...
