三丙酮胺性狀描述： 該品為白色或淡黃色粉末，熔點(diǎn)43℃，沸點(diǎn)205℃，比重0.92g/cm3，閃點(diǎn)92℃，能溶于丙酮，醇，醚和水。三丙酮胺本身的穩(wěn)定性不好，一般在有空氣存在下放置3~4天后，就會(huì)由原來的乳白色變?yōu)榈S色甚至棕紅色。放置時(shí)間越長，物料顏色越深。
三丙酮胺質(zhì)量標(biāo)準(zhǔn):
外觀 淺黃色至棕紅色熔融體
純度 ≥97.0%（GC）
灰分 ≤0.10%
水分 ≤1.20%
三丙酮胺用途： 主要作為合成受阻胺類光穩(wěn)定劑的母體。經(jīng)它還原制得的2,2,6,6-四甲基-r-哌啶醇是制取新型高效光穩(wěn)定劑770、GW-540(cas95733-09-8 [亞磷酸三(1,2,2,6,6-五甲基哌啶醇)酯])和HALS的重要原料，同時(shí)也是制取4-取代硫基-2,2,6,6-四甲基哌啶氨氧自由基化合物的重要中間體。
