补充资料：乙酰氯
| 乙酰氯 acetyl chloride 乙酸中的羟基被氯原子取代而生成的化合物 。分子式CH3COCl。无色液体，有刺激性气味。熔点－112℃，沸点50.9℃，相对密度1.1051（20／4℃）。能与乙醚、丙酮、苯和氯仿混溶。乙酰氯易水解成乙酸和氯代氢，在湿空气中发烟，对眼鼻有刺激性。乙酰氯具有酰卤的通性，例如，能进行水解、醇解和氨解反应，也能与芳香族化合物发生芳环上的酰基化反应。工业上，乙酰氯可由乙烯酮与氯化氢反应，或由乙酸钠、二氧化硫与氯气反应制得。实验室中可由乙酸、乙酸钠或乙酸酐与各种氯化剂反应制得。乙酰氯是重要的乙酰化试剂，酰化能力比乙酸酐强，广泛用于有机合成。乙酰氯也是羧酸发生氯化反应的催化剂，还可用于羟基或氨基的定量分析。乙酰氯有毒，因它能与蛋白质中的巯基（-SH）结合。 |
