异丙叉丙酮是食品添加剂吗

不是，该物质对环境可能有危害，对水体应给予特别注意

常温常压下稳定。 能与乙醇、乙醚、丙酮、芳香烃、庚烷、四氯化碳等多种有机溶剂混溶。对纤维素酯、纤维素醚、聚苯乙烯、乙烯共聚物、油脂、烃、松香、合成橡胶等溶解能力强。可溶于水。 本品有毒，操作人员应带好防护用具。长时间与空气接触发生氧化和聚合而变色。氧化时生成的过氧化物在蒸馏时有爆炸的危险，常加入二异丙胺作稳定剂。对金属无明显的腐蚀作用。 化学性质：亚异丙基丙酮分子中含有羰基和与羰基共轭的双键，故富有反应性。除具有酮类的一般性质外，还容易发生氧化、聚合等反应。与酸作用时生成双丙酮醇和丙酮。与稀硝酸作用生成草酸和乙酸。与稀硫酸作用生成丙酮。亚异丙基丙酮能进行α-，β-不饱和酮的各种反应。2,4-二甲基苯腙的熔点为200℃。亚异丙基丙酮与异构体CH2C(CH3)-CH2COCH3之间存在着平衡，其平衡组成比为91：9。 毒性较高，在(250~500)*10-6下，除有麻醉作用外，还能引起蛋白尿、尿浑浊和浮肿等肾脏障碍。在50*10-6下，对人体无害，但对咽喉、眼有刺激作用，其不愉快的臭味能持续3~6小时，即使在25*10-6下，对眼也有刺激作用。要求设备密封，操作人员应配戴好防护用具。空气中最高容许浓度0.5*10-6。
