摘　　要：采用浸渍法制备了固体磷酸催化剂,用Hammett指示剂法研究了焙烧温度及浸渍时间对固体磷酸催化剂酸强度范围及不同酸强度下酸量的影响。结果表明,浸渍时间一定时,催化剂的总酸量及各酸强度下的酸量都随着焙烧温度的升高而降低,焙烧温度一定时,催化剂的总酸量随着浸渍时间的增加而增大。This paper prepares the solid phosphoric acid catalyst by using impregnation methods, studi of sintering temperature and maceration time on the acid strength scope of solid phosphoric acid catalyst under different acid strength. The results show that when the maceration time is fixed, the total acidity of the acidity under each acid strength will go down along with the going up of the sintering temperature, wh temperature is fixed, the total acidity will go up along with the increase of the maceration time. es the influence and the acidity the catalyst and ile the sintering
