过氧化尿素又称过碳酸酰胺,它是过氧化氢和尿素的加合物,分子式为CO(NH_2)_2·H_2O_2,相对分子质量为94.07,外观为白色结晶粉末,理论活性氧含量为17.02%,易溶于水,水溶液兼有过氧化氢和尿素的性质,溶液的pH=3～4,稳定性较好,在水中缓慢放出氧气。干燥的过氧化尿素在低温密封条件下保存相当稳定,几个月内不会变质,若遇热受潮,分解度显著增大,在65℃～75℃之间变软融化,其活性氧含量迅速下降,过氧化尿素受到有催化作用的物质如铁、铜、铅、锰等重金属离子影响时会迅速分解,与过氧化尿素
Peroxide urea, also known as percarbonate, is an adduct of hydrogen peroxide and urea. The molecular formula is CO (NH 2) 2 · H 2 O 2, the relative molecular mass is 94.07, and the appearance is white crystalline powder. The theoretical active oxygen content is 17.02% , Soluble in water, aqueous solution of both hydrogen peroxide and urea nature of the solution pH = 3 ~ 4, good stability, the slow release of oxygen in water. The dry urea peroxide is quite stable under low temperature sealing conditions and will not deteriorate within a few months. In case of heat dampness, the decomposition degree increases significantly and becomes soft and melted at 65 ° C to 75 ° C. The reactive oxygen species is rapidly Decline, urea peroxide by catalytic substances such as iron, copper, lead, manganese and other heavy metal ions will rapidly decompose, and urea peroxide
