摘　　要：利用热重技术考察了反应温度和MgO含量对癸酸与醋酸合成甲基壬基酮MgO/浮石催化剂积炭的影响。确证镁盐流失不是积炭的直接原因,而反应温度对积炭有明显影响,适当调整反应温度可减少积炭的生成。The influences of reaction temperature and amount of MgO inMgO/pumice catalyst on the coke deposits during the conversion of mixture ofdecanoic acid with acetic acid to methyl n-nonyl ketone have been examined bythemogravimetry. It is obvious that the reaction temperature, not the loss ofMgO in MgO/pumice has an influence on the coke deposits which can be decre-ased with proper reaction temperature,
