| 摘 要： | 利用公式△H=-0．1196n／A计算了乙醚和丙酮分别在氧气和空气中燃烧反应的温度，并推测了乙醚和丙酮燃烧反应的机理．乙醚在氧气中燃烧反应的火焰温度理论值为3272K，与测定温度3134K接近，误差为4．40％．丙酮在空气中燃烧反应的火焰温度理论值为1292K，与测定温度173K接近，误差为1．49％．根据乙醚和丙酮燃烧反应的火焰温度，推测乙醚和丙酮燃烧反应机理为：（1）O2＋hv→2O·；（2）（C2H5）2O→4C＋4H2＋H2O（乙醚），CH3COCH3→3C＋2H2＋H2O（丙酮）；（3）H2＋O·→H2O＋hv；（4）C＋O·→CO＋hv；（5）2CO＋O2→2CO2．

| Abstract: | The flame temperatures produced by ethyl ether and acetone burning in oxygen and air in order were calculated by the formula △H = -0. 1196nA, and the mechanisms of ethyl ether and acetone combustion reactions were deduced. The theoretical flame temperature of ethyl ether burning in oxygen was 3272K, near to its actual temperature 3134K, the error was 4.40%. The theoretical flame temperature of acetone burning in air was 1292K, near to its actual temperature 1273K, the error was 1.49%. According to the flame tempera- tures, the mechanisms of ethyl ether and acetone combustion reactions were deduced as follow： （ 1 ） O2 ＋ hv→ 2O ; （2） （ C2 H5 ） 2O→4C ＋ 4H2 ＋ H2O （ ethyl ether）, CH3 COCH3→3 C ＋ 2 H2 ＋ H2O （ acetone ） ; （ 3 ） H2 ＋O→H2O ＋ bv; （4）C ＋ O→CO ＋ hv; （5）2CO ＋ O2→2CO2. |
