<*n style="font-family:SimSun;">Ammonium persulfate
<*n style="font-family:SimSun;">Cas<*n style="font-family:SimSun;">号<*n>: 7727-54-0
<*n style="font-family:SimSun;">分子式<*n> H8N2O8S2；<*n> (NH4)2S2O8
<*n style="font-family:SimSun;">分子量<*n> 228.20
<*n style="font-family:SimSun;">别名<*n> ****<*n>,****<*n>
<*n style="font-family:SimSun;">Ammonium persulfate
<*n style="font-family:SimSun;">性状<*n> 白色结晶或粉末，无气味。在<*n>120°<*n>C 完全分解，完全干燥时可长期保存不分解，不易吸潮，但吸潮后逐渐分解放出氧和臭氧。加热则分解出氧气而成为<*n>(NH4)2S2O7。强氧化剂。易溶于水，水溶液呈酸性。在室温中逐渐分解，在较高温度时很快分解放出氧气，并生成**。<*n>
<*n style="font-family:SimSun;">密度<*n>1.98
