摘　　要：为了快捷地对造纸原料的苯醇抽提物进行检测,实验用微波加热方法代替水浴加热。主要考察了功率和时间两个因素对苯醇抽提率的影响。结果表明,对2g稻草粉末做苯醇抽提物检测时,采用微波辐射15min,辐射功率中低火,可获得与传统的恒温水浴反应6h同样的检测效果。经重复实验,微波法大幅提高了检测效率,并且具有一定的稳定性。Microwave irradiation is used in paper making material test. In the experiment, the radiation heating is used to replace the water-bath heating. Two main factors are established as irradiation power and time. According to the experiment data, the best irradiation conditions that benzene-alcohol extraction ratio is at the same level as water-bath heating for 600min are as follows： irradiation power is 320W, irradiation time is 15min. After the testing experiments, it is concluded that the radiation heating raise the efficiency of detecting meanwhile it also has good stability.
