描述

产品介绍 有愉快的气味。受光作用会变棕色成树脂状物。能与乙醇、苯、氯仿、乙醚、丙酮、冰乙酸混溶,1份约溶于8份水中。与许多金属生成能溶于有机溶剂和和有挥发性的盐。易燃。低毒,半数致死量(大鼠,经口)1000mg/kg。
别名 乙酰丙酮 ;二乙酰基甲烷,2,4-戊二酮 ;Diacetyl methane 2,4-Pentanedione
备注 产品 通常为烯醇式和酮式两种互变异构体的混合物,二者处于动态平衡中,烯醇式异构体在分子内形成氢键,混合物中,酮式约占18%,烯醇式占82%。将混合物的石油醚溶液冷却至-78℃,烯醇式就以固体形式析出,使二者分离;当烯醇式恢复室温,又自动处于上述平衡状态。
应用 有机合成,色层分析用试剂,过渡金属螯合剂。比色法测定铁和氟,在二硫化碳存在时测定铊。
