毒理性
鉴定和使用:乙酰基乙烯酮是一种无色液体,室温静置后会变成黄褐色。它用于生产乙酰芳酰胺、颜料和调色剂、农药、食品防腐剂、药物中间体。它还用作合成有机化学中的试剂。人体研究:无数据可用。动物研究:在小鼠经皮肤应用或皮下注射,以及在大鼠皮下注射后,它不具有致癌性。对小鼠、大鼠、豚鼠和家兔的长期毒性测试表明,即使接触到新鲜生成的乙酰基乙烯酮的浓度低至116 ppm,十分钟的暴露也是致命的。
IDENTIFICATION AND USE: Acetyl ketene is a colorless liquid, which turns brownish-yellow upon standing at room temperature. It is used in the production of acetoarylamides, pigments and toners, pesticides, food preservatives, pharmaceutical intermediates. It is also used as a reagent in synthetic organic chemistry. HUMAN STUDIES: There are no data available. ANIMAL STUDIES: it was not carcinogenic in mice following dermal application or sc injection, and in rats after sc injection. Extended toxicity testing on mice, rats, guinea pigs and rabbits showed that ten minute exposures to concentrations of freshly generated acetyl ketene as low as 116 ppm was lethal.
